Debian DLA-2519-1 : pacemaker security update

high Nessus Plugin ID 144814

Synopsis

The remote Debian host is missing a security update.

Description

Several security vulnerabilities were addressed in pacemaker, a cluster resource manager.

CVE-2018-16877

A flaw was found in the way pacemaker's client-server authentication was implemented. A local attacker could use this flaw, and combine it with other IPC weaknesses, to achieve local privilege escalation.

CVE-2018-16878

An insufficient verification inflicted preference of uncontrolled processes can lead to denial of service.

CVE-2020-25654

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.

For Debian 9 stretch, these problems have been fixed in version 1.1.24-0+deb9u1.

We recommend that you upgrade your pacemaker packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
