Debian DSA-3400-1 : lxc - security update

high Nessus Plugin ID 86954

Synopsis

The remote Debian host is missing a security-related update.

Description

Roman Fiedler discovered a directory traversal flaw in LXC, the Linux Containers userspace tools. A local attacker with access to a 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.

Solution

Upgrade the lxc packages.

For the stable distribution (jessie), this problem has been fixed in version 1:1.0.6-6+deb8u2.
