Microsoft Security Bulletin MS08-076 - Important

Vulnerabilities in Windows Media Components Could Allow Remote Code Execution (959807)

Published: | Updated:

Version: 5.0

General Information

Executive Summary

This security update resolves two privately reported vulnerabilities in the following Windows Media components: Windows Media Player, Windows Media Format Runtime, and Windows Media Services. The most severe vulnerability could allow remote code execution. 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 Important for Windows Media Player 6.4, Windows Media Format Runtime 7.1, Windows Media Format Runtime 9.0, Windows Media Format Runtime 9.5, Windows Media Format Runtime 11, Windows Media Services 4.1, Windows Media Services 9 Series, and Windows Media Services 2008. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the first vulnerability by modifying the way that Windows Media authentication replies are validated. The security update addresses the second vulnerability by ensuring that Windows Media clients treat servers using ISATAP addresses as external. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Recommendation. Microsoft recommends that customers apply the update at the earliest opportunity.
