More information:

Multiple security issues in systemd have been discovered by Sebastian Krahmer and Florian Weimer: Insecure interaction with DBUS could lead to the bypass of Policykit restrictions and privilege escalation or denial of service through an integer overflow in journald and missing input sanitising in the processing of X keyboard extension (XKB) files.

For the stable distribution (wheezy), these problems have been fixed in version 44-11+deb7u4.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your systemd packages.
