Detail

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
