NVD Description

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

In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port.
