[***** Start Microsoft Security Bulletin (MS07-047) *****] Microsoft Security Bulletin MS07-047 - Important Vulnerabilities in Windows Media Player Could Allow Remote Code Execution (936782) Published: August 14, 2007 | Updated: September 19, 2007 Version: 1.2 General Information Executive Summary This important security update resolves two privately reported vulnerabilities. These vulnerabilities could allow code execution if a user viewed a specially crafted file in Windows Media Player. 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 is an important security update for supported versions of Windows Media Player 7.1, 9, 10, and 11. For more information, see the subsection, Affected and Non-Affected Software, in this section. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Update Information Detection and Deployment Tools and Guidance Manage the software and security updates you need to deploy to the servers, desktop, and mobile computers in your organization. For more information see the TechNet Update Management Center. The Microsoft TechNet Security Web site provides additional information about security in Microsoft products. Security updates are available from Microsoft Update, Windows Update, and Office Update. Security updates are also available at the Microsoft Download Center. You can find them most easily by doing a keyword search for "security_patch." Finally, security updates can be downloaded from the Windows Update Catalog. For more information about the Windows Update Catalog, see Microsoft Knowledge Base Article 323166. Detection and Deployment Guidance Microsoft has provided detection and deployment guidance for this month’s security updates. This guidance will also help IT professionals understand how they can use various tools to help deploy the security update, such as Windows Update, Microsoft Update, Office Update, the Microsoft Baseline Security Analyzer (MBSA), the Office Detection Tool, Microsoft Systems Management Server (SMS), the Extended Security Update Inventory Tool, and the Enterprise Update Scan Tool (EST). For more information, see Microsoft Knowledge Base Article 910723. Microsoft Baseline Security Analyzer and Enterprise Update Scan Tool (EST) Microsoft Baseline Security Analyzer (MBSA) allows administrators to scan local and remote systems for missing security updates as well as common security misconfigurations. For more information about MBSA, visit Microsoft Baseline Security Analyzer. MBSA 1.2.1 does not support detection for this security update. The Enterprise Update Scan Tool does, and is what customers can use instead of MBSA 1.2.1. For download links and more information about the version of EST that is being released this month, see Microsoft Knowledge Base Article 894193. SMS customers should also see the heading, Systems Management Server, for more information about SMS and EST. The following table provides the MBSA and EST detection summary for this security update. Software MBSA 1.2.1 EST MBSA 2.0.1 Windows Media Player 7.1 Yes Not Applicable Yes Windows Media Player 9 Yes Not Applicable Yes Windows Media Player 10 No Yes Yes Windows Media Player 11 No No Yes Note for Windows Vista Microsoft does not support installing MBSA 2.0.1 on computers that run Windows Vista, but you may install MBSA 2.0.1 on a supported operating system and then scan the Windows Vista-based computer remotely. For additional information about MBSA support for Windows Vista, visit the MBSA Web site. See also Microsoft Knowledge Base Article 931943: Microsoft Baseline Security Analyzer (MBSA) support for Windows Vista. For more information about MBSA, visit the MBSA Web site. For more information about the software that Microsoft Update and MBSA 2.0 currently do not detect, see Microsoft Knowledge Base Article 895660. Windows Server Update Services By using Windows Server Update Services (WSUS), administrators can deploy the latest critical updates and security updates for Windows 2000 operating systems and later, Office XP and later, Exchange Server 2003, and SQL Server 2000 to Windows 2000 and later operating systems. For more information about how to deploy this security update using Windows Server Update Services, visit the Windows Server Update Services Web site. Systems Management Server The following table provides the SMS detection and deployment summary for this security update. Software SMS 2.0 EST SMS 2003 Windows Media Player 7.1 Yes Yes Yes Windows Media Player 9 Yes Yes Yes Windows Media Player 10 Yes (with EST) Yes Yes Windows Media Player 11 No No Yes SMS 2.0 and SMS 2003 Software Update Services (SUS) Feature Pack can use MBSA 1.2.1 for detection and therefore have the same limitation that is listed earlier in this bulletin related to programs that MBSA 1.2.1 does not detect. For SMS 2.0, the SMS SUS Feature Pack, which includes the Security Update Inventory Tool (SUIT), can be used by SMS to detect security updates. SMS SUIT uses the MBSA 1.2.1 engine for detection. For more information about SUIT, visit the following Microsoft Web site. For more information about the limitations of SUIT, see Microsoft Knowledge Base Article 306460. The SMS SUS Feature Pack also includes the Microsoft Office Inventory Tool to detect required updates for Microsoft Office applications. For SMS 2003, the SMS 2003 Inventory Tool for Microsoft Updates (ITMU) can be used by SMS to detect security updates that are offered by Microsoft Update and that are supported by Windows Server Update Services. For more information about the SMS 2003 ITMU, visit the following Microsoft Web site. SMS 2003 can also use the Microsoft Office Inventory Tool to detect required updates for Microsoft Office applications. Note for Windows Vista Microsoft Systems Management Server 2003 with Service Pack 3 includes support for Windows Vista manageability. For more information about SMS, visit the SMS Web site.
