The March 2011 Microsoft Security Bulletin Release

The March 2011 Microsoft Security Bulletin Release

Today, as part of our monthly security bulletin release, we have three bulletins addressing four vulnerabilities in Microsoft Windows and Microsoft Office. One bulletin is rated Critical, and this is the bulletin we recommend for priority deployment:

  • MS11-015. This bulletin resolves one Critical-level and one Important-level vulnerability affecting certain media files in all versions of Microsoft Windows. It has an Exploitability Index rating of 1. Due to the nature of the affected software, this bulletin carries a Critical-level severity rating for all affected client systems, but only an Important-level rating for Windows Server 2008 R2 for x64. Other versions of Windows Server - 2003, 2008 and 2008 R2 - are unaffected. For both the Critical- and Important-level vulnerabilities, an attacker would have to convince a user to open a maliciously crafted file for an attack to work.

Our other two bulletins are somewhat similar in nature, both addressing the DLL-preloading issue described in Security Advisory 2269637, and both carrying an Important-level severity rating and an Exploitability Index rating of 1.

  • MS11-016 is a DLL-preloading issue affecting Microsoft Groove 2007 Service Pack 2, which makes this an Office bulletin. Versions 2007 and 2010 of Groove are unaffected, as is Microsoft SharePoint Workspace 2010.
  • MS11-017 is also a DLL-preloading issue, in this instance in Microsoft Windows Remote Client Desktop. This security update is rated Important for Remote Desktop Connection 5.2 Client, Remote Desktop Connection 6.0 Client, Remote Desktop Connection 6.1 Client, and Remote Desktop Connection 7.0 Client.

We continue to address DLL-preloading issues as they are discovered; however, it's important to note that we have not seen exploitation of these issues in the wild.
