This issue was patched in RHSA-2016:1420.

NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd24-mod_session package and not the httpd24-mod_session package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The Apache HTTP Server 2.4.18 through 2.4.20, when mod_http2 and mod_ssl are enabled, does not properly recognize the "SSLVerifyClient require" directive for HTTP/2 request authorization, which allows remote attackers to bypass intended access restrictions by leveraging the ability to send multiple requests over a single connection and aborting a renegotiation.
