While this may seem perfectly obvious to you and I, not all sysadmins
are intimately familiar with the internals of TCP/IP and inetd.conf.
If your suggestion would indeed have prevented security from being
breached then it should DEFINITELY have been explained in that same
warning about the hole.

IMHO, if there is no readily available workaround, then full disclosure
is bad. But there must be plenty of experts available for private
consultation on these matters so that the announcements could be
delayed for a few hours while a workaround is prepared and documented.
