Synopsis

The remote Rocky Linux host is missing a security update.

Description

The remote Rocky Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2022:6313 advisory.

 - 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)
