Title: DSA-3099-1 -- dbus security update
Description: Simon McVittie discovered that the fix for <a href="https://security-tracker.debian.org/tracker/CVE-2014-3636">CVE-2014-3636</a> was incorrect, as it did not fully address the underlying denial-of-service vector. This update starts the D-Bus daemon as root initially, so that it can properly raise its file descriptor count.
