Description

The remote host is affected by the vulnerability described in GLSA-202309-09 (Pacemaker: Multiple Vulnerabilities)

 - A flaw was found in the way pacemaker's client-server authentication was implemented in versions up to and including 2.0.0. A local attacker could use this flaw, and combine it with other IPC weaknesses, to achieve local privilege escalation. (CVE-2018-16877)

 - A flaw was found in pacemaker up to and including version 2.0.1. An insufficient verification inflicted preference of uncontrolled processes can lead to DoS (CVE-2018-16878)

 - A use-after-free flaw was found in pacemaker up to and including version 2.0.1 which could result in certain sensitive information to be leaked via the system logs. (CVE-2019-3885)

 - An ACL bypass flaw was found in pacemaker. An attacker having a local account on the cluster and in the haclient group could use IPC communication with various daemons directly to perform certain tasks that they would be prevented by ACLs from doing if they went through the configuration. (CVE-2020-25654)

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