Security Bulletin Release for March, 2011

Microsoft released three (3) security bulletins today addressing four vulnerabilities in Microsoft Windows and Microsoft Office. One bulletin is rated Critical and two are rated Important.

The two Important bulletins address the DLL-preloading issue described in Security Advisory 2269637.  As noted in the MSRC Blog that, while Microsoft continues to address DLL-preloading issues as they are discovered, Microsoft has not seen exploitation of these issues in the wild.

  • 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.

  • 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.


The following information is provided in the Security Bulletin:
  • The affected software listed have been tested to determine which versions are affected. Other versions are past their support life cycle. To determine the support life cycle for your software version, visit Microsoft Support Lifecycle.
  • Customers in the U.S. and Canada can receive technical support from Security Support or 1-866-PCSAFETY. There is no charge for support calls that are associated with security updates. For more information about available support options, see Microsoft Help and Support.
  • International customers can receive support from their local Microsoft subsidiaries. There is no charge for support that is associated with security updates. For more information about how to contact Microsoft for support issues, visit International Help and Support.
