+Subject: [PATCH] chan_sip.c: Prevent address change on unauthenticated SIP request.
+
+If the name of a peer is known and a SIP request is sent using that
+peer's name, the address of the peer will change even if the request
+fails the authentication challenge. This means that an endpoint can
+be altered and even rendered unusuable, even if it was in a working
+state previously. This can only occur when the nat option is set to the
+default, or auto_force_rport.
+
+This change checks the result of authentication first to ensure it is
+successful before setting the address and the nat option.

+Subject: [PATCH] manager.c: Prevent the Originate action from running the Originate app
+
+If an AMI user without the "system" authorization calls the
+Originate AMI command with the Originate application,
+the second Originate could run the "System" command.
+
+Action: Originate
+Channel: Local/1111
+Application: Originate
+Data: Local/2222,app,System,touch /tmp/owned
+
+If the "system" authorization isn't set, we now block the
+Originate app as well as the System, Exec, etc. apps.
