AlmaLinux 9.2 [TuxCare] Security Update: mod_auth_openidc (ALMALINUX9.2:CLSA-2025:1745945082)

high Nessus Plugin ID 361947

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has a package installed that is affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2025:1745945082 advisory.

 - 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`. (CVE-2023-28625)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected mod_auth_openidc package based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2025:1745945082.
