Summary of Microsoft’s Security Bulletin Release for December 2009

imageFrom the MSRC blog:

As noted in our Advance Notification (ANS) last Thursday, for the December bulletin release we issued six security bulletins addressing 12 vulnerabilities. Affected products include Windows, Internet Explorer (IE) and Microsoft Office products.

In the ANS, we also noted that the bulletin for IE (MS09-072) is at the top of our deployment priority list this month. As you can see from our Severity and Exploitability Index slide (also referred to as the Risk and Impact slide), MS09-072 is the only bulletin this month that has both a Critical severity rating and our maximum Exploitability Index rating of 1. Of note, each of the five vulnerabilities addressed in this bulletin are Critical and each also have an Exploitability Index rating of 1. One of the vulnerabilities was the subject of Security Advisory 977981 due to public disclosure and affects IE 6 and IE 7 so customers running those versions should install this update as soon as possible.
