Microsoft Security Bulletin MS08-054 - Critical
Vulnerability in Windows Media Player Could Allow Remote Code Execution (954154)
Published: | Updated:
This security update resolves a privately reported vulnerability in Windows Media Player that could allow remote code execution when a specially crafted audio file is streamed from a Windows Media server. 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 Windows Media Player 11. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerability by correcting the manner in which Windows Media Player 11 handles audio files streamed from a server-side playlist (SSPL). For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
