Microsoft March 2011 Security Bulletin Release

Angela Gunn: 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.
