Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. The `HttpPostRequestDecoder` can be tricked to accumulate data. While the decoder can store items on the disk if configured so, there are no limits to the number of fields the form can have, an attacher can send a chunked post consisting of many small fields that will be accumulated in the `bodyListHttpData` list. The decoder cumulates bytes in the `undecodedChunk` buffer until it can decode a field, this field can cumulate data without limits. This vulnerability is fixed in 4.1.108.Final.

Jonathan Leitschuh discovered that Netty did not correctly handle file
permissions when writing temporary files. An attacker could possibly use
this issue to leak sensitive information. (CVE-2022-24823)
It was discovered that Netty did not correctly handle limiting the number
of fields when decoding a HTTP request. An attacker could possibly use
issue to cause a denial of service. This issue only affected
Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and
Ubuntu 24.04 LTS. (CVE-2024-29025)

CVE-2024-29025 [MEDIUM] Netty's HttpPostRequestDecoder can OOM
Netty's HttpPostRequestDecoder can OOM
### Summary
The `HttpPostRequestDecoder` can be tricked to accumulate data. I have spotted currently two attack vectors
### Details
1. While the decoder can store items on the disk if configured so, there are no limits to the number of fields the form can have, an attacher can send a chunked post consisting of many small fields that will be accumulated in the `bodyListHttpData` list.
2. The decoder cumulates bytes in the `undecodedChunk` buffer until it can decode a field, this field can cumulate data without limits
### PoC
Here is a Netty branch that provides a fix + tests : https://github.com/vietj/netty/tree/post-request-decoder
Here is a reproducer with Vert.x (which uses this decoder) https://gist.github.com/vietj/f558b8ea81ec6505f1e9a6ca28
