If your firewall blocks smb (port 139 and 445) from remote unknown IP's
then this isn't much of a concern. Think of it as a blockable version of
winnuke. Winnuke was actually much worse as it was the tcp/ip stack, this
requires access to smb which most firewalls and all NAT devices block by
default. Anyone running the XP firewall is already protected.
