Bulletin Identifier Microsoft Security Bulletin MS11-015
Bulletin Title Vulnerabilities in Windows Media Could Allow Remote Code Execution (2510030)
Executive Summary This security update resolves one publicly disclosed vulnerability in DirectShow and one privately reported vulnerability in Windows Media Player and Windows Media Center. The more severe of these vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Digital Video Recording (.dvr-ms) file.

 

The security update addresses the vulnerabilities by modifying the way library files and Windows media files are opened.

Severity Ratings and Affected Software This security update is rated Critical for affected editions of Windows XP (including Windows XP Media Center Edition 2005); all supported editions of Windows Vista and Windows 7; and Windows Media Center TV Pack for Windows Vista. This security update is also rated Important for all supported editions of Windows Server 2008 R2 for x64-based systems.
Attack Vectors
  • A specially crafted .dvr-ms file.
  • A legitimate WMP file that is located in the same directory as a specially crafted dynamic link library (DLL) file.
  • A maliciously crafted DLL.
Mitigating Factors
  • A user must visit a remote file system location or WebDAV share and open a WMP file.
  • SMB is commonly disabled on perimeter firewalls.
  • Users must be persuaded to visit a malicious site.
  • Exploit only gains the logged-on account user rights.
  • Cannot be exploited automatically through email, because a user must open an attachment that is sent in an email message.
Restart Requirement May require restart.
