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 :

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.
