Debian DSA-5405-1 : libapache2-mod-auth-openidc - security update

high Nessus Plugin ID 176076

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 host has a package installed that is affected by a vulnerability as referenced in the dsa-5405 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

Upgrade the libapache2-mod-auth-openidc packages.

For the stable distribution (bullseye), this problem has been fixed in version 2.4.9.4-0+deb11u3.
