MS08-037 : More entropy for the DNS resolver
Tuesday, July 08, 2008
We released security bulletin MS08-020 two months ago to improve the DNS transaction ID entropy. You can read more about the MS08-020 algorithm change in this blog entry. Increasing the entropy makes it more difficult for attackers to spoof DNS replies. Today, we released MS08-037 to further increase the difficulty of spoofing DNS transactions.
