NVD Description

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

Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow
