Description OSIDB Bzimport 2026-07-27 14:37:32 UTC 
Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final, the HTTP decoder in netty-codec-http fails to properly limit decompression of HTTP body content encoded with gzip or other compression algorithms. An attacker can send HTTP requests with highly compressed payloads that decompress to enormous sizes, causing memory exhaustion and denial of service. This issue is fixed in versions 4.1.136.Final and later.
