How to fix?

There is no fixed version for RHEL:7 netty-codec-http.

NVD Description

Note: Versions mentioned in the description apply only to the upstream netty-codec-http package and not the netty-codec-http package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in Netty's HTTP/1 decoder. Incomplete validation of malformed Transfer-Encoding headers allows a remote attacker to perform HTTP request smuggling. By sending specially crafted HTTP requests, an attacker can inject arbitrary HTTP requests, potentially bypassing security controls or accessing unauthorized resources.
