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.");
