NVD Description

Note: Versions mentioned in the description apply only to the upstream netty-tcnative package and not the netty-tcnative package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

Netty is a network application framework for development of protocol servers and clients. In netty-codec-redis prior to versions 4.1.135.Final and 4.2.15.Final, an attacker can cause DoS by sending crafted Redis payloads across multiple connections without \r\n. This exhausts the server's direct memory pool (OutOfDirectMemoryError), preventing legitimate connections from being processed. Versions 4.1.135.Final and 4.2.15.Final patch the issue.
