Bulletin Information

Executive Summaries

The following table summarizes the security bulletins for this month in order of severity.

For details on affected software, see the next section, Affected Software and Download Locations.

Bulletin ID	Bulletin Title and Executive Summary	Maximum Severity Rating and Vulnerability Impact	Restart Requirement	Affected Software
MS12-029	Vulnerability in Microsoft Word Could Allow Remote Code Execution (2680352) This security update resolves a privately reported vulnerability in Microsoft Office. The vulnerability could allow remote code execution if a user opens a specially crafted RTF file. An attacker who successfully exploited the vulnerability could gain the same user rights as the current 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.	Critical Remote Code Execution	May require restart	Microsoft Office
MS12-034	Combined Security Update for Microsoft Office, Windows, .NET Framework, and Silverlight (2681578) This security update resolves three publicly disclosed vulnerabilities and seven privately reported vulnerabilities in Microsoft Office, Microsoft Windows, the Microsoft .NET Framework, and Microsoft Silverlight. The most severe of these vulnerabilities could allow remote code execution if a user opens a specially crafted document or visits a malicious webpage that embeds TrueType font files. An attacker would have no way to force users to visit a malicious website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website.	Critical Remote Code Execution	May require restart	Microsoft Windows, Microsoft .NET Framework, Microsoft Silverlight, Microsoft Office
MS12-035	Vulnerabilities in .NET Framework Could Allow Remote Code Execution (2693777) This security update resolves two privately reported vulnerabilities in the .NET Framework. The vulnerabilities could allow remote code execution on a client system if a user views a specially crafted webpage using a web browser that can run XAML Browser Applications (XBAPs). 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.	Critical Remote Code Execution	May require restart	Microsoft Windows, Microsoft .NET Framework
MS12-030	Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2663830) This security update resolves one publicly disclosed and five privately reported vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Office file. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the logged-on 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.	Important Remote Code Execution	May require restart	Microsoft Office
MS12-031	Vulnerability in Microsoft Visio Viewer 2010 Could Allow Remote Code Execution (2597981) This security update resolves a privately reported vulnerability in Microsoft Office. The vulnerability could allow remote code execution if a user opens a specially crafted Visio file. An attacker who successfully exploited the vulnerability could gain the same user rights as the current 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.	Important Remote Code Execution	May require restart	Microsoft Office
MS12-032	Vulnerability in TCP/IP Could Allow Elevation of Privilege (2688338) This security update resolves one privately reported and one publicly disclosed vulnerability in Microsoft Windows. The more severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to a system and runs a specially crafted application.	Important Elevation of Privilege	Requires restart	Microsoft Windows
MS12-033	Vulnerability in Windows Partition Manager Could Allow Elevation of Privilege (2690533) This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker logs on to a system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.	Important Elevation of Privilege	Requires restart	Microsoft Windows

Detection and Deployment Tools and Guidance

Security Central

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 TechNet Security Center provides additional information about security in Microsoft products. Consumers can visit Security At Home, where this information is also available by clicking "Latest Security Updates".

Security updates are available from Microsoft Update and Windows 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".

For customers of Microsoft Office for Mac, Microsoft AutoUpdate for Mac can help keep your Microsoft software up to date. For more information about using Microsoft AutoUpdate for Mac, see Check for software updates automatically.

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 provides detection and deployment guidance for security updates. This guidance contains recommendations and information that can help IT professionals understand how to use various tools for detection and deployment of security updates. For more information, see Microsoft Knowledge Base Article 961747.

Microsoft Baseline Security Analyzer

The 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.

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 Microsoft Windows 2000 operating systems and later, Office XP and later, Exchange Server 2003, and SQL Server 2000 to Microsoft Windows 2000 and later operating systems.

For more information about how to deploy this security update using Windows Server Update Services, visit Windows Server Update Services.

System Center Configuration Manager 2007

Configuration Manager 2007 Software Update Management simplifies the complex task of delivering and managing updates to IT systems across the enterprise. With Configuration Manager 2007, IT administrators can deliver updates of Microsoft products to a variety of devices including desktops, laptops, servers, and mobile devices.

The automated vulnerability assessment in Configuration Manager 2007 discovers needs for updates and reports on recommended actions. The Software Update Management in Configuration Manager 2007 is built on Microsoft Windows Software Update Services (WSUS), a time-tested update infrastructure that is familiar to IT administrators worldwide. For more information about how administrators can use Configuration Manager 2007 to deploy updates, see Software Update Management. For more information about Configuration Manager, visit System Center Configuration Manager.

Systems Management Server 2003

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 to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users.

Note System Management Server 2003 is out of mainstream support as of January 12, 2010. For more information on product lifecycles, visit Microsoft Support Lifecycle. The next release of SMS, System Center Configuration Manager 2007, is now available; see the earlier section, System Center Configuration Manager 2007.

For more information about how administrators can use SMS 2003 to deploy security updates, see Scenarios and Procedures for Microsoft Systems Management Server 2003: Software Distribution and Patch Management. For information about SMS, visit the Microsoft Systems Management Server TechCenter.

Note SMS uses the Microsoft Baseline Security Analyzer 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 SMS in these cases to target updates to specific systems. For more information about this procedure, see Deploying Software Updates Using the SMS Software Distribution Feature. 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) to install these updates.

Update Compatibility Evaluator and Application Compatibility Toolkit

Updates often write to the same files and registry settings required for your applications to run. This can trigger incompatibilities and increase the time it takes to deploy security updates. You can streamline testing and validating Windows updates against installed applications with the Update Compatibility Evaluator components included with Application Compatibility Toolkit.

The Application Compatibility Toolkit (ACT) contains the necessary tools and documentation to evaluate and mitigate application compatibility issues before deploying Windows Vista, a Windows Update, a Microsoft Security Update, or a new version of Windows Internet Explorer in your environment.
