RE: Firewalls

So a TCP/IP buffer overflow won't crash Windows? Windows handles all TCP/IP
processing first so in essence it is still vulnerable.

While that is true, it may not be quite as bad as it sounds. Firewalls like
Winroute Pro actually preempt the OS and intercept all TCP/IP traffic to
apply
filters, NAT, port mapping, etc prior to Win 9x/NT/W2K/XP ever seeing the
traffic.

So with proper filtering you can create a black hole which blocks many
exploits
which may otherwise work under Windows.
