    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.
