Mac OS X & Darwin/BSD vulnerable to telnetd overflow

telnet> close
Connection closed.

Note that by default telnet is disabled in /etc/inetd.conf (as are 
most things, except for portmapper/NFS, ugh) so the impact should be 
minimal. If you're not using the OpenSSH included with OS X, you're 
mad.

This was tested successfully on Mac OS X 10.0.4 from both the local 
machine, and from a remote Sparc Solaris 2.7 host.

I'd notify Apply, only I have no idea what address to use, and it's 
6am and I've not slept yet (catching up to bugtraq from a 2 week 
holiday, wow, that Code Red thing was bad, glad I wasn't around when 
THAT baby hit, ho ho ho)
