CVE-2024-29025 affects multiple packages. This issue is resolved in later releases. See references for individual vulnerability details.

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.

Affected: Maven: io.netty:netty-codec-http

### 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/f558b8ea81ec6505f1e9a6ca283c9ae3

### Impact Any Netty based HTTP server that uses the `HttpPostRequestDecoder` to decode a form.

Affected: openEuler:24.03-LTS: netty3, openEuler:22.03-LTS-SP4: netty3, openEuler:22.03-LTS-SP3: netty3, openEuler:20.03-LTS-SP4: netty3, openEuler:22.03-LTS-SP1: netty3

Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server.
