How to fix?

Upgrade SLES:15.2 apache2-mod_auth_openidc to version 2.3.8-150100.3.25.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream apache2-mod_auth_openidc package and not the apache2-mod_auth_openidc package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when OIDCStripCookies is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using OIDCStripCookies.
