Description (partial)

The rpcbind process on the TED opens ports within the IANA well-known port range (0-1023).  This is in addition to the expected standard 111 rpcbind port. For security and network security appliance management purposes the rpcbind process on the TED should not have the wrong protocols running on well-known ports.

lsof +M -P | grep rpcbind | grep -v 111 | grep \:
Observe that the rpcbind process has ports open within the IANA well-known port range (0-1023).
