    Package        : dbus
    CVE ID         : CVE-2015-0245
    Debian Bug     : 777545
    
    Simon McVittie discovered a local denial of service flaw in dbus, an
    asynchronous inter-process communication system. On systems with
    systemd-style service activation, dbus-daemon does not prevent forged
    ActivationFailure messages from non-root processes. A malicious local
    user could use this flaw to trick dbus-daemon into thinking that systemd
    failed to activate a system service, resulting in an error reply back to
    the requester.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.6.8-1+deb7u6.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.8.16-1.
    
    We recommend that you upgrade your dbus packages.
