    Sebastian Krahmer discovered that the xrdb utility of x11-xserver-utils,
    a X server resource database utility, is not properly filtering crafted
    hostnames.  This allows a remote attacker to execute arbitrary code with
    root privileges given that either remote logins via xdmcp are allowed or
    the attacker is able to place a rogue DHCP server into the victims network.
