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.");
