Ubuntu Security Notice USN-2753-3
October 05, 2015
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
USN-2753-1 introduced a regression in LXC.
- lxc: Linux Containers userspace tools
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 a path that contained a '/./' directory
specified as a bind mount target in their configuration file. This
update fixes the problem. We apologize for the inconvenience.
Original advisory details:
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.
The problem can be corrected by updating your system to the following
Ubuntu 14.04 LTS:
In general, a standard system update will make all the necessary changes.
