So is this a paid Microsoft advertisment?

is added. 
ASLR in Vista solves this so remote exploitation of overflows has 
just got a 
lot harder. I've not done a thorough analysis yet but, all going 
well, this 
is a fantastic way for Microsoft to go and builds on the work done 

with 
NX/DEP and stack cookies/canaries.
