    Package : das-watchdog
    CVE ID : CVE-2015-2831
    Debian Bug : 781806

    Adam Sampson discovered a buffer overflow in the handling of the
    XAUTHORITY environment variable in das-watchdog, a watchdog daemon to
    ensure a realtime process won't hang the machine. A local user can
    exploit this flaw to escalate his privileges and execute arbitrary
    code as root.

    For the stable distribution (wheezy), this problem has been fixed in
    version 0.9.0-2+deb7u1.

    For the unstable distribution (sid), this problem has been fixed in
    version 0.9.0-3.1.

    We recommend that you upgrade your das-watchdog packages.
