NVD Description

Note: Versions mentioned in the description apply only to the upstream zipkin package and not the zipkin package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

Netty is an asynchronous, event-driven network application framework. From 4.2.0.Final to 4.2.13.Final , Netty's epoll transport fails to detect and close TCP connections that receive a RST after being half-closed, leading to stale channels that are never cleaned up and, in some code paths, a 100% CPU busy-loop in the event loop thread. This vulnerability is fixed in 4.2.13.Final.
