Ubuntu 14.04 LTS : lxc regression (USN-2753-2)

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 :

USN-2753-1 fixed a vulnerability in LXC. The update caused a
regression that prevented some containers from starting. This
regression only affected containers that had an absolute path
specified as a bind mount target in their configuration file. This
update fixes the problem.

We apologize for the inconvenience.

Roman Fiedler discovered a directory traversal flaw in lxc-start. A
local attacker with access to an LXC container could exploit this flaw
to run programs inside the container that are not confined by AppArmor
or expose unintended files in the host to the container.

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 lxc package.
