Netty versions prior to 4.1.135.Final and 4.2.15.Final have a vulnerability in HTTP/2 max header size handling that can cause an attack similar to HTTP/2 Rapid Reset. When a client sends the SETTINGS_MAX_HEADER_LIST_SIZE setting, Netty processes the request but throws an exception while writing response headers. This behavior can disrupt service availability. The issue is patched in versions 4.1.135.Final and 4.2.15.Final.

Netty, a network application framework, has a vulnerability in its HTTP/2 max header size handling prior to versions 4.1.135.Final and 4.2.15.Final. Specifically, when a client sends the SETTINGS_MAX_HEADER_LIST_SIZE setting, Netty reads and proxies the request, attempts to produce a response, but then throws an exception during response header writing. This results in behavior similar to the HTTP/2 Rapid Reset attack but with a different network signature. The vulnerability can lead to denial of service conditions. The issue is fixed in versions 4.1.135.Final and 4.2.15.Final.
