Ubuntu Security Notice USN-3224-1
March 09, 2017

lxc vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

LXC could be made to create arbitrary virtual network interfaces as an
administrator.

Software Description:
- lxc: Linux Containers userspace tools

Details:

Jann Horn discovered that LXC incorrectly verified permissions when creating
virtual network interfaces. A local attacker could possibly use this issue to
create virtual network interfaces in network namespaces that they do not own.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.10:
lxc-common 2.0.7-0ubuntu1~16.10.2

Ubuntu 16.04 LTS:
lxc-common 2.0.7-0ubuntu1~16.04.2

Ubuntu 14.04 LTS:
lxc 1.0.9-0ubuntu3

In general, a standard system update will make all the necessary changes.
