CyberRota Analysis
AI-GeneratedNetty's SPDY SETTINGS decoder is vulnerable to a denial-of-service attack due to excessive heap growth caused by processing a large number of unique SETTINGS entries from a remote peer. This can lead to significant resource consumption and potential service disruption. Organizations using affected versions of Netty should prioritize upgrading to versions 4.1.136.Final or 4.2.16.Final to mitigate this risk.

Original NVD Description
Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final and 4.2.16.Final, Netty's SPDY SETTINGS decoder accepts a peer-declared SETTINGS entry count up to the 24-bit frame-length limit and materializes every unique setting ID in `DefaultSpdySettingsFrame`, allowing a remote SPDY/3.1 peer to send a syntactically valid roughly 2 MiB SETTINGS frame that creates 262144 map entries and amplifies network input into heap growth and ordered-map insertion work. This issue is fixed in versions 4.1.136.Final and 4.2.16.Final.
