NVD Description

Note: Versions mentioned in the description apply only to the upstream eap8-netty-handler-proxy package and not the eap8-netty-handler-proxy package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.124.Final and 4.2.4.Final, Netty is vulnerable to MadeYouReset DDoS. This is a logical vulnerability in the HTTP/2 protocol, that uses malformed HTTP/2 control frames in order to break the max concurrent streams limit - which results in resource exhaustion and distributed denial of service. This issue has been patched in versions 4.1.124.Final and 4.2.4.Final.
