Ubuntu 14.04 LTS / 14.10 : cgmanager vulnerability (USN-2451-1)

Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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.

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

Solution :

Update the affected cgmanager package.

Risk factor :

Low / CVSS Base Score : 2.1
(CVSS2#AV:L/AC:L/Au:N/C:N/I:P/A:N)
