As expected, Microsoft today released its regular monthly batch of security bulletins and associated patches. This month there are six bulletins, addressing 17 identified vulnerabilities; four bulletins have a Critical severity rating, one is rated Important, and one Moderate. Five of the bulletins are for Windows and its components; every supported version of Windows — even the just-released Windows 8 and Windows RT — has at least one Critical bulletin. The remaining bulletin is for Microsoft Office (including Office for Mac) and is rated Important. (For a breakdown of bulletin severity by Windows version, please see this month’s preview post.) Full details, and download links, are in the Microsoft Security Bulletin Summary for November 2012.
Microsoft says that three of the bulletins will definitely require a system restart; the others may require one, depending on the system’s configuration.
The handlers at the SANS Internet Storm Center have posted their usual summary of the patch release, along with their severity assessments.
As usual, I recommend applying these patches to your systems as soon as you conveniently can.
