30th September, 2015

lxc regression

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

  • Ubuntu 14.04 LTS

Summary

USN-2753-1 introduced a regression in LXC.

Software description

  • lxc
    – Linux Containers userspace tools

Details

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 an absolute path 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
package version:

Ubuntu 14.04 LTS:
lxc

1.0.7-0ubuntu0.6
