Kerentanan Missing Release of Resource after Effective Lifetime pada netty. Skor CVSS 3.1 7.5 (High) menurut github.com.

Deskripsi (NVD)

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.
