    Package : lxc
    CVE ID : CVE-2015-1331 CVE-2015-1334
    Debian Bug : 793298

    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.
