There's not much of a difference between this and them getting a telnet prompt. Sure they can look at your front door, but they don't get anywhere unless they have a key. If this is still a big problem, look into /etc/host.deny, or see what port it is on and try /etc/services.
Found it in /etc/services, comment these out and restart inetd (killall -HUP inetd): xdmcp 177/tcp # X Display Mgr.
