Debian DSA-5226-1 : pcs - security update

high Nessus Plugin ID 164812

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5226 advisory.

- A flaw was found in the Pacemaker configuration tool (pcs). The pcs daemon was allowing expired accounts, and accounts with expired passwords to login when using PAM authentication. Therefore, unprivileged expired accounts that have been denied access could still login. (CVE-2022-1049)

- A vulnerability was found in the PCS project. This issue occurs due to incorrect permissions on a Unix socket used for internal communication between PCS daemons. A privilege escalation could happen by obtaining an authentication token for a hacluster user. With the hacluster token, this flaw allows an attacker to have complete control over the cluster managed by PCS. (CVE-2022-2735)

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

Solution

Upgrade the pcs packages.

For the stable distribution (bullseye), these problems have been fixed in version 0.10.8-1+deb11u1.
