Top of sectionTop of section General Information Executive Summary This update resolves two newly discovered, privately reported and public vulnerabilities. Each vulnerability is documented in this bulletin in its own "Vulnerability Details" section. When using vulnerable versions of Office, if a user were logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of the client workstation. 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. We recommend that customers apply the update immediately. Severity Ratings and Vulnerability Identifiers: Vulnerability Identifiers Impact of Vulnerability Microsoft PowerPoint 2000 Microsoft PowerPoint XP Microsoft PowerPoint 2003 Microsoft PowerPoint 2004 for Mac or Microsoft PowerPoint v. X for Mac Microsoft PowerPoint Mso.dll Vulnerability - CVE-2006-3590 Remote Code Execution Critical Important Important Important Microsoft PowerPoint Malformed Records Vulnerability - CVE-2006-3449 Remote Code Execution Critical Important Important Important Aggregate Severity of All Vulnerabilities Critical Important Important Important This assessment is based on the types of systems that are affected by the vulnerability, their typical deployment patterns, and the effect that exploiting the vulnerability would have on them. Top of sectionTop of section Vulnerability Details Microsoft PowerPoint Mso.dll Vulnerability - CVE-2006-3590 A remote code execution vulnerability exists in PowerPoint and could be exploited when a file containing a malformed shape container is parsed by PowerPoint. Such a file might be included in an e-mail attachment or hosted on a malicious web site. An attacker could exploit the vulnerability by constructing a specially crafted PowerPoint file that could allow remote code execution. If a user were 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 affected than users who operate with administrative user rights. Mitigating Factors for Microsoft PowerPoint Mso.dll Vulnerability - CVE-2006-3590 • An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. 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. • In Outlook 2002 and Outlook 2003, the vulnerability could not be exploited automatically through e-mail. A user would have to click on an attachment and then acknowledge a warning and accept a prompt to Open before the vulnerability could be exploited. • In a Web-based attack scenario, an attacker could host a Web site that contains a Web page that is used to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or instant messenger message that takes users to the attacker's Web site. Note PowerPoint 2000 files do not prompt the user to Open, Save, or Cancel before opening a document. Top of sectionTop of section Microsoft PowerPoint Malformed Record Vulnerability - CVE-2006-3449 A remote code execution vulnerability exists in PowerPoint and could be exploited when a file containing a malformed record is parsed by PowerPoint. Such a file might be included in an e-mail attachment or hosted on a malicious web site. An attacker could exploit the vulnerability by constructing a specially crafted PowerPoint file that could allow remote code execution. If a user were 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 affected than users who operate with administrative user rights.

For more information about how to deploy security updates by using Software Update Services, visit the Software Update Services Web site. Windows Server Update Services: By using Windows Server Update Services (WSUS), administrators can quickly and reliably 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 onto Windows 2000 and later operating systems. For more information about how to deploy security updates using Windows Server Update Services, visit the Windows Server Update Services Web site. Systems Management Server: Microsoft Systems Management Server (SMS) delivers a highly configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and can perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. For more information about how administrators can use SMS 2003 to deploy security updates, visit the SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack to help deploy security updates. For information about SMS, visit the SMS Web site. Note SMS uses the Microsoft Baseline Security Analyzer, the Microsoft Office Detection Tool, and the Enterprise Update Scanning Tool to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to target updates to specific systems. For more information about this procedure, visit the following Web site. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
