Vulnerability in Windows Media Encoder 9 Could Allow Remote Code Execution
Description: 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. The security update addresses the vulnerability by performing additional parameter validation and modifying the way that controls in Windows Media Encoder interact with Internet Explorer.
