Name of the Vulnerable Software and Affected Versions mod auth openidc versions 2.0.0 through 2.4.13.1

Description The issue is related to the mod auth openidc module for the Apache 2.x HTTP server, which implements OpenID Connect Relying Party functionality. When OIDCStripCookies is set and a crafted cookie is supplied, a NULL pointer dereference occurs, resulting in a segmentation fault. This can be used in a Denial-of-Service attack, presenting an availability risk.

Recommendations For mod auth openidc versions 2.0.0 through 2.4.13.1, update to version 2.4.13.2 to resolve the issue. As a temporary workaround, avoid using OIDCStripCookies to minimize the risk of exploitation.
