Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : Pacemaker vulnerability (USN-4623-1)

high Nessus Plugin ID 142729

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4623-1 advisory.

 Ken Gaillot discovered that Pacemaker incorrectly handled IPC communications permissions. A local attacker could possibly use this issue to bypass ACL restrictions and execute arbitrary code as root.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
