Doc Text:
A flaw was found in the Netty netty-codec-http component. A remote attacker can send HTTP requests containing highly compressed data. The HTTP decoder in netty-codec-http fails to properly limit the decompression of this content, causing the system to consume excessive memory. This can lead to memory exhaustion and a denial of service (DoS), making the service unavailable to legitimate users.

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.
