Microsoft Patch Tuesday, May 2012

Today is the second Tuesday of May, so, in keeping with its usual schedule, Microsoft has released this month’s batch of security bulletins and patches for Windows and related software.  This month, there are seven bulletins, for 22 identified vulnerabilities.    Three are for Windows and its components, three are for Microsoft Office (including Office for Mac), and one affects Windows, Office, and Silverlight.  Three of the bulletins have a maximum severity rating of Critical, and four are rated Important.  All  supported versions of Windows are affected, with two Critical vulnerabilities.   For a breakdown of patches by version and severity, check this month’s preview post.

Further details, and download links, are in the Security Bulletin Summary for May  2012.  Microsoft says that two of the patch installations will definitely require a system restart, and the others may require one, depending on the configuration of your system.

The folks at the SANS Internet Storm Center have posted their usual analysis of this month’s patches, along with their severity ratings for client and server systems.

As always, I recommend that you update your systems as soon as you conveniently can.
