-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
