+ TCPMUX services
+
+Originally reported to Debian in 2005 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=324678> and rediscovered <https://bugzilla.redhat.com/show_bug.cgi?id=1006100>, xinetd would execute TCPMUX services without dropping privilege to match the service configuration allowing the service to run with same privilege as the xinetd process (root).
