These vulnerabilities could allow an anonymous remote attacker to run code with the privileges of the logged on user. If a user subscribed to a malicious RSS feed in the Feed Headlines Gadget or added a malicious contacts file in the Contacts Gadget or a user clicked on a malicious link in the Weather Gadget an attacker could potentially run code on the system. In all attack vectors, 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 all supported editions of Windows Vista. For more information, see the subsection, Affected and Non-Affected Software, in this section. This security update addresses the vulnerability by improving validation code within the Feed Headlines and Contacts Gadgets. The Inspect Your Gadget document outlines secure programming best practices that should be followed when building Gadgets. 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 security update. Known Issues: Microsoft Knowledge Base Article 938123 documents any currently known issues that customers may experience when they install this security update. The article also documents recommended solutions for these issues.

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 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. The following table provides the MBSA detection summary for this security update. Software MBSA 1.2.1 MBSA 2.0.1 Windows Vista No See Note for Windows Vista below Windows Vista x64 Edition No See Note for Windows Vista below 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. 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.
