Ubuntu 14.04 LTS : cgmanager vulnerability (USN-2451-1)

high Nessus Plugin ID 80392

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2451-1 advisory.

 Serge Hallyn discovered that cgmanager did not consistently enforce proper nesting when modifying cgroup properties. A local attacker in a privileged container could use this to set cgroup values for all cgroups.

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.
