I guess this will become a FAQ rather quickly.
There's a DoS with the X server listening to TCP connections. The
Debian packages use sources where the impact of this has been
minimized. In some people's opinion, having the X sever listen to TCP
ports as default (DoS or not) is a bad idea, allegedly there could be
other, more serious problems. The Debian packages default to disabling
listening on TCP ports. Look in /etc/X11/xinit/xserverrc or (sorry,
the name escapes mei atm) /etc/X11/xdm/Xserver. (which, BTW, is the
wrong solution IMO, there are more applications calling the X server
besides xdm or xinit. At any rate, the place to fix this is
/etc/X11/XF86Config*)
