This vulnerability could allow remote code execution if a user viewed a specially crafted Web page. The vulnerability could be exploited through attacks on Object Linking and Embedding (OLE). 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 a critical security update for all supported editions of Windows 2000, Windows XP, Office 2004 for Mac, and Visual Basic 6. For other affected editions of Windows, this update is rated moderate. For more information, see the subsection, Affected and Non-Affected Software, in this section. This security update addresses the vulnerability by adding a check on memory requests within OLE Automation. For more information about the vulnerability, 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 immediately. Known Issues: Microsoft Knowledge Base Article 921503 documents the currently known issues that customers may experience when they install this security update. The article also documents recommended solutions for these issues.

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 Analyzerand 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 Web site. MBSA 1.2.1 does not support detection for some platforms affected by 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 2000 Service Pack 4 Yes No Yes Windows XP Service Pack 1 and Windows XP Service Pack 2 Yes No Yes Windows XP Professional x64 Edition and Windows XP Professional x64 Edition Service Pack 2 No No Yes Windows Server 2003 Service Pack 1 and Windows Server 2003 Service Pack 2 Yes No Yes Windows Server 2003 x64 Edition and Windows Server 2003 x64 Edition Service Pack 2 No No Yes Windows Server 2003 with SP1 for Itanium-based Systems and Windows Server 2003 with SP2 for Itanium-based Systems No No Yes Microsoft Office 2004 for Mac No No No Microsoft Visual Basic 6.0 Service Pack 6 No Yes No Note MBSA does not support Microsoft Visual Basic 6.0 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.

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. For more information about SMS, visit the SMS Web site.
