Microsoft Security Bulletin MS10-027 - Critical
Vulnerability in Windows Media Player Could Allow Remote Code Execution (979402)

The security update addresses the vulnerability by modifying the way the Windows Media Player ActiveX control handles specially crafted media content hosted on a malicious Web site.
