X.Org security advisory: root hole via rogue hostname
Quote:
By crafting hostnames with shell escape characters, arbitrary commands
can be executed in a root environment when a display manager reads in
the resource database via xrdb.
These specially crafted hostnames can occur in two environments:
* Hosts that set their hostname via DHCP
* Hosts that allow remote logins via xdmcp
