Microsoft has been busy, with several patches expected to appear on Tuesday, according to this article on CNET.  There are bulletins posted at Microsoft detailing the patch, and there will be a broadcast on Wednesday as well.
“The Exchange e-mail server and at least one of the Windows alerts is deemed “critical,” Microsoft’s highest risk rating, the software maker said in a notice posted on its Web site on Thursday. Such flaws typically allow a full compromise of a vulnerable system without any, or minimal, user interaction.

Microsoft did not specify how many flaws the updates will tackle, or say which components of Windows and Exchange are being repaired. Security researchers over the past weeks have reported several unpatched flaws in Internet Explorer, the Web browser component of Windows.”
