Note: Versions mentioned in the description apply only to the upstream mod_ssl package and not the mod_ssl package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

A NULL pointer dereference in the mod_authn_socache in Apache HTTP Server 2.4.66 and earlier allows an unauthenticated remote user to crash a child process in a caching forward proxy configuration.

Users are recommended to upgrade to version 2.4.67, which fixes this issue.
