Microsoft Security RC Blog

Hello,

Today we published the January Security Bulletin Webcast Questions & Answers page. We fielded nine questions on various topics during the webcast, including bulletins released, deployment tools, and update detection tools. There were two questions during the webcast that we were unable to answer and we have included those questions and answers on the Q&A page.

We invite our customers to join us for the next public webcast on Wednesday, February 15 at 11am PST (UTC -8), when we will go into detail about the February bulletin release and answer questions live on the air.

Customers can register to attend at the link below:

Hello. As I previously mentioned in the Advance Notification Service blog post on Thursday, today we are releasing seven security bulletins, one of which is rated Critical in severity, with the remaining six classified as Important.

These bulletins will address eight vulnerabilities in Microsoft products. Customers should plan to install all of these updates as soon as possible. For those who must prioritize deployment, we recommend focusing first on the sole critical update:

• MS12-004 (Windows Media Player): Vulnerabilities in Windows Media Player Could Cause Remote Code Execution. This bulletin – the only one in January’s set to include multiple CVEs – addresses two issues that could arise if a would-be attacker sent a malicious MIDI or DirectShow file to a targeted user. Both of these issues were cooperatively disclosed to Microsoft, and we know of no active exploitation in the wild. Still, we recommend that customers read through the bulletin information concerning MS12-004 and apply it as soon as possible.

In the video at the bottom of this post, Pete Voss discusses this month's bulletins in further detail.

As always, we recommend that customers deploy all security updates as soon as possible. Below is our deployment priority guidance to further assist customers in their deployment planning (click for larger view).

Our risk and impact graph shows an aggregate view of this month's severity and exploitability index (click for larger view).

You can find more information about this month's security updates on the Microsoft Security Bulletin Summary web page.

As you may remember, last month we announced a bulletin addressing the SSL issue we described in Security Advisory 2588513. Days before release, we noted a compatibility problem that might have affected certain users of third-party products, and decided to hold that bulletin until we could complete further investigation. We’re-releasing that bulletin today as MS12-006; we’re also providing further information and guidance to customers with a Knowledge Base article and a Fix-it that will be useful in certain installation circumstances.

As usual, our colleagues in SRD have prepared blog posts that delve more deeply into technical details of this month’s releases. In addition to a discussion of this month’s deployment priorities, SRD has a post examining some of the finer points of MS12-001, which addresses an Important-class issue affecting the SafeSEH security mitigation, and an overview of the aforementioned MS12-004.

Per our usual process, we’ll offer the monthly technical webcast on Wednesday, hosted by Pete Voss and Dustin Childs. I invite you to tune in and learn more about the January security bulletins, as well as other announcements made today. The webcast is scheduled for tomorrow, January 11, 2012, at 11 A.M. PST.
