GHSA-fx2c-96vj-985v: HAProxyMessageDecoder Stack Exhaustion DoS

### Impact A StackOverflowError can be raised when parsing a malformed crafted message due to an infinite recursion. ### Patches Users should upgrade to 4.1.86.Final ### Workarounds There is no workaround, except using a custom HaProxyMessageDecoder. ### References When parsing a TLV with type = PP2_TYPE_SSL, the value can be again a TLV with type = PP2_TYPE_SSL and so on. The only limitation of the recursion is that the TLV length cannot be bigger than 0xffff because it is encoded in an unsigned short type. Providing a TLV with a nesting level that is large enough will lead to raising of a StackOverflowError. The StackOverflowError will be caught if HAProxyMessageDecoder is used as part of Netty’s ChannelPipeline, but using it directly without the ChannelPipeline will lead to a thrown exception / crash. ### For more information If you have any questions or comments about this advisory: * Open an issue in [netty](https://github.com/netty/netty)

CVE-2022-41881: HAProxyMessageDecoder Stack Exhaustion DoS

Netty project is an event-driven asynchronous network application framework. In versions prior to 4.1.86.Final, a StackOverflowError can be raised when parsing a malformed crafted message due to an infinite recursion. This issue is patched in version 4.1.86.Final. There is no workaround, except using a custom HaProxyMessageDecoder.

CVE-2022-41854

Those using Snakeyaml to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stack overflow. This effect may support a denial of service attack.
