Microsoft says that it will fix seven flaws in  Windows, Office, Exchange and BizTalk, next week.

Microsoft's 'bug Tuesday' will fix two holes in Windows, three affect Microsoft Office, and one each impact Microsoft Exchange and the cryptography API within BizTalk Server. Five of the flaws are critical.

It is fairly likely that one of the bugs fixed will be for the DNS (Domain Name System) zero-day bug found in all editions of Microsoft's server line.
