ms06-040 ETA?

Does Hardware DEP prevent it, or does it overflow in the code segment?

This is a plain old stack overflow actually, the tricky part is that
exploiting XP and 2003 requires you bypass /GS protection. What bothers
me the most about this bug is that I had a PoC for it six months ago,
but overlooked an NDR encoding issue and couldn't reproduce it...
