‘Vulnerability in Windows Media Encoder 9 Allows Code Execution (MS08-053)’

Summary

This security update resolves a privately reported vulnerability in Windows Media Encoder 9 Series. The vulnerability could allow remote code execution if a user viewed a specially crafted Web page. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update is rated Critical for all supported and affected editions of Microsoft Windows 2000, Windows XP, and Windows Vista, and Moderate for supported and affected versions of Windows Server 2003 and Windows Server 2008. For more information, see the subsection, Affected and Non-Affected Software, in this section.’
