[***** Start Microsoft Security Bulletin (MS08-015) *****] Microsoft Security Bulletin MS08-015 - Critical Vulnerability in Microsoft Outlook Could Allow Remote Code Execution (949031) Published: March 11, 2008 | Updated: June 4, 2008 Version: 1.5 General Information Executive Summary This security update resolves a privately reported vulnerability in Microsoft Office Outlook. The vulnerability could allow remote code execution if Outlook is passed a specially crafted mailto URI. 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 vulnerability is not exploitable by simply viewing an e-mail through the Outlook preview pane. This security update is rated Critical for supported editions of Microsoft Office Outlook 2000 Service Pack 3, Outlook 2002 Service Pack 3, Outlook 2003 Service Pack 2 and Service Pack 3, and Outlook 2007. For more information, see the subsection, Affected and Non-Affected Software, in this section. This security update addresses these vulnerabilities by modifying the way that Microsoft Outlook handles mailto URIs. For more information about the vulnerability, 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 update." Finally, security updates can be downloaded from the Microsoft Update Catalog. The Microsoft Update Catalog provides a searchable catalog of content made available through Windows Update and Microsoft Update, including security updates, drivers and service packs. By searching using the security bulletin number (such as, “MS07-036”), you can add all of the applicable updates to your basket (including different languages for an update), and download to the folder of your choosing. For more information about the Microsoft Update Catalog, see the Microsoft Update Catalog FAQ. 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 2.0.1 Microsoft Outlook 2000 Service Pack 3 No Microsoft Outlook XP Service Pack 3 Yes Microsoft Outlook 2003 Service Pack 2 and Service Pack 3 Yes Microsoft Outlook 2007 Yes For more information about MBSA 2.0.1, see MBSA 2.0 Frequently Asked Questions. Note For customers using legacy software not supported by MBSA 2.0.1, Microsoft Update, and Windows Server Update Services: please visit Microsoft Baseline Security Analyzer and reference the Legacy Product Support section on how to create comprehensive security update detection with legacy tools. 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 SMS 2003 with SUSFP SMS 2003 with ITMU SCCM 2007 Microsoft Outlook 2000 Service Pack 3 Yes Yes No No Microsoft Outlook XP Service Pack 3 Yes Yes Yes Yes Microsoft Outlook 2003 Service Pack 2 and Service Pack 3 Yes Yes Yes Yes Microsoft Outlook 2007 No No Yes Yes For SMS 2.0 and SMS 2003, the SMS SUS Feature Pack (SUSFP), 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. System Center Configuration Manager (SCCM) 2007 uses WSUS 3.0 for detection of updates. For more information about SCCM 2007 Software Update Management, visit System Center Configuration Manager 2007. For more information about SMS, visit the SMS Web site. For more detailed information, see Microsoft Knowledge Base Article 910723: Summary list of monthly detection and deployment guidance articles. Note If you have used an Administrative Installation Point (AIP) for deploying Office 2000, Office XP or Office 2003, you may not be able to deploy the update using SMS if you have updated the AIP from the original baseline. For more information, see the Office Administrative Installation Point heading in this section. Office Administrative Installation Point If you installed your application from a server location, the server administrator must update the server location with the administrative update and deploy that update to your system. • For supported versions of Microsoft Office 2000, see How to Create an Administrative Installation Point. For more information about how to change the source for a client system from an updated administrative installation point to an Office 2000 original baseline source or Service Pack 3 (SP3), see Microsoft Knowledge Base Article 932889. Note If you plan to manage software updates centrally from an updated administrative image, you can find more information in the article, Updating Office 2000 Clients from a Patched Administrative Image. • For supported versions of Microsoft Office XP, see Creating an Administrative Installation Point. For more information on how to change the source for a client system from an updated administrative installation point to an Office XP original baseline source or Service Pack 3 (SP3), see Microsoft Knowledge Base Article 922665. Note If you plan to manage software updates centrally from an updated administrative image, you can find more information in the article Updating Office XP Clients from a Patched Administrative Image. • For supported versions of Microsoft Office 2003, see Creating an Administrative Installation Point. If you have an Administrative Installation Point with a non- supported version of Microsoft Office 2003, see Microsoft Knowledge Base Article 902349. Note If you plan to manage software updates centrally from an updated administrative image, you can find more information in the article Distributing Office 2003 Product Updates. • For supported versions of the 2007 Microsoft Office system, see Create a network installation point for the 2007 Office system.
