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 versions:
