Subject: Cox is blocking port 135 - off topic

You might want to drop Todd Sabin a note at Razor Bindview and ask him.
He's the one that apparently exposed the potential for other ports (137,
445, 539).  My expeirences with Todd over the years is that he rarely
discloses a potential for vulnerabilty unless there is a reason.  And, he
rarely plays games.

But, then - everyone gets bored now and again....

I don't think DCOM is used on any other port besides 135. When i disabled
dcom using dcomcnfg.exe, the only port that stopped listening was 135.

and for the specifics for how the buffer overflow
works(http://www.lsd-pl.net/special.html) - "In a result of implementation
error in a function responsible for instantiation of DCOM objects, remote
attackers can obtain remote access to vulnerable systems."

People claim that the same buffer overflow works on the SMB port(445) which
is an entirely different service, but can they prove it?
