+Subject: [PATCH] Missing signal sending permission check on failed query
+ messages
+
+When run as setuid root, one can send a query message to the
+privileged screen process via its unix socket in order to force
+it to send SIGHUP to a PID that can be freely specified in the
+query packet.
+Processes that do not explicitly handle SIGHUP will simply terminate
