lxc - security update

Several vulnerabilities have been discovered in LXC, the Linux
Containers userspace tools. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2015-1331
  Roman Fiedler discovered a directory traversal flaw in LXC when
  creating lock files. A local attacker could exploit this flaw to
  create an arbitrary file as the root user.
• CVE-2015-1334
  Roman Fiedler discovered that LXC incorrectly trusted the
  container’s proc filesystem to set up AppArmor profile changes and
  SELinux domain transitions. A malicious container could create a
  fake proc filesystem and use this flaw to run programs inside the
  container that are not confined by AppArmor or SELinux.

For the stable distribution (jessie), these problems have been fixed in
version 1:1.0.6-6+deb8u1.

For the testing distribution (stretch), these problems have been fixed
in version 1:1.0.7-4.

For the unstable distribution (sid), these problems have been fixed in
version 1:1.0.7-4.

We recommend that you upgrade your lxc packages.
