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.</p> <p>### For more information If you have any questions or comments about this advisory: * Open an issue in [netty](https://github.com/netty/netty)</p> <p><strong>Affected:</strong> Maven: io.netty:netty-codec-haproxy</p> <p>### Impact A StackOverflowError can be raised when parsing a malformed crafted message due to an infinite recursion.</p> <p>### Patches Users should upgrade to 4.1.86.Final.</p> <p>### Workarounds There is no workaround, except using a custom HaProxyMessageDecoder.</p> <p>### 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.
