NVD Description

Note: Versions mentioned in the description apply only to the upstream mod_auth_openidc:2.3/cjose-devel package and not the mod_auth_openidc:2.3/cjose-devel package as distributed by RHEL. See How to fix? for RHEL:8 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.
