NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd:2.4/mod_session package and not the httpd:2.4/mod_session package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL.
