========================================================================== 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.
