Microsoft Security Bulletin MS11-039 - Critical
Vulnerability in .NET Framework and Microsoft Silverlight Could Allow Remote Code Execution (2514842)
Published: June 14, 2011
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Microsoft .NET Framework and Microsoft Silverlight. The vulnerability could allow remote code execution on a client system if a user views a specially crafted Web page using a Web browser that can run XAML Browser Applications (XBAPs) or Silverlight applications. 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. The vulnerability could also allow remote code execution on a server system running IIS, if that server allows processing ASP.NET pages and an attacker succeeds in uploading a specially crafted ASP.NET page to that server and then executes the page, as could be the case in a Web hosting scenario. This vulnerability could also be used by Windows .NET applications to bypass Code Access Security (CAS) restrictions.
This security update is rated Critical for all affected releases of Microsoft .NET Framework for Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2; and Microsoft Silverlight 4. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerability by correcting the manner in which the .NET Framework validates values passed to trusted APIs. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Frequently Asked Questions (FAQ) Related to This Security Update
Where are the file information details?
Refer to the reference tables in the Security Update Deployment section for the location of the file information details.
Is this security update related to MS11-044, Vulnerability in .NET Framework Could Allow Remote Code Execution?
No. Although both of these updates affect the .NET Framework, the security updates affect different components within the .NET Framework and are not related. These updates may be applied in any order.
How do I determine which version of the Microsoft .NET Framework is installed?
You can install and run multiple versions of the .NET Framework on a system, and you can install the versions in any order. There are several ways to determine which versions of the .NET Framework are currently installed. For more information, please see Microsoft Knowledge Base Article 318785.
What is the difference between .NET Framework 4.0 and .NET Framework 4.0 Client Profile?
The .NET Framework version 4 redistributable packages are available in two profiles: .NET Framework 4.0 and .NET Framework 4.0 Client Profile. The .NET Framework 4.0 Client Profile is a subset of the .NET Framework 4.0 profile that is optimized for client applications. It provides functionality for most client applications, including Windows Presentation Foundation (WPF), Windows Forms, Windows Communication Foundation (WCF), and ClickOnce features. This enables faster deployment and a smaller install package for applications that target the .NET Framework 4.0 Client Profile. For more information, see .NET Framework Client Profile.
What is Microsoft Silverlight?
Microsoft Silverlight is a cross-browser, cross-platform implementation of the Microsoft .NET Framework for building media experiences and rich interactive applications for the Web. For more information, see the official site of Microsoft Silverlight.
Which Web browsers support Microsoft Silverlight applications?
In order to run Microsoft Silverlight applications, most Web browsers, including Microsoft Internet Explorer, require Microsoft Silverlight to be installed and the corresponding plug-in to be enabled. For more information about Microsoft Silverlight, see the official site, Microsoft Silverlight. Please refer to the documentation of your browser to learn more about how to disable or remove plug-ins.
What versions of Microsoft Silverlight 4 are affected by the vulnerability?
Microsoft Silverlight build 4.0.60531.0, which is the current build of Microsoft Silverlight as of when this bulletin was first released, addresses the vulnerability and is not affected. Builds of Microsoft Silverlight previous to 4.0.60531.0 are affected.
How do I know which version and build of Microsoft Silverlight is currently installed?
If Microsoft Silverlight is already installed on your computer, you can visit the Get Microsoft Silverlight page, which will indicate which version and build of Microsoft Silverlight are currently installed on your system. Alternatively, you can use the Manage Add-Ons feature of current versions of Microsoft Internet Explorer to determine the version and build information that is currently installed.
You can also manually check the version number of sllauncher.exe located in the "%ProgramFiles%\Microsoft Silverlight" directory (on x86 Microsoft Windows systems) or in the "%ProgramFiles(x86)%\Microsoft Silverlight" directory (on x64 Microsoft Windows systems).
In addition, on Microsoft Windows, the version and build information of the currently installed version of Microsoft Silverlight can be found in the registry at [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Silverlight]:Version on x86 Microsoft Windows systems, or [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Silverlight]:Version on x64 Microsoft Windows systems.
On Apple Mac OS, the version and build information of the currently installed version of Microsoft Silverlight can be found as follows:
1.
Open the Finder
2.
Select the system drive and go to the folder Internet Plug-ins - Library
3.
Right-click the file Silverlight.Plugin (if your mouse has only one button, press the Ctrl key while clicking on the file) to bring up the context menu, then click Show Package Contents
4.
Inside the contents folder, locate the file info.plist and open it with an editor. It will contain an entry like this, which shows you the version number:
SilverlightVersion
4.0.60531.0
The version installed with this security update is 4.0.60531.0. If your version number is higher than or equal to this version number, your system is not vulnerable.
How do I upgrade my version of Microsoft Silverlight?
The Microsoft Silverlight auto-update feature helps makes sure that your Microsoft Silverlight installation is kept up to date with the latest version of Microsoft Silverlight, Microsoft Silverlight functionality, and security features. For more information about the Microsoft Silverlight auto-update feature, see the Microsoft Silverlight Updater. Customers who have disabled the Microsoft Silverlight auto-update feature can enroll in Microsoft Update to obtain the latest version of Microsoft Silverlight, or download the latest version of Microsoft Silverlight manually using the download link in the Affected Software table in the earlier section, Affected and Non-Affected Software. For information about deploying Microsoft Silverlight in an enterprise environment, see the Silverlight Enterprise Deployment Guide.
I have .NET Framework 3.0 Service Pack 2 installed; this version is not listed among the affected software in this bulletin. Do I need to install an update?
This bulletin describes a vulnerability in the .NET Framework 2.0 and the .NET Framework 4.0 feature layers. The .NET Framework 3.0 Service Pack 2 installer chains in the .NET Framework 2.0 Service Pack 2 setup, so installing the former also installs the latter. Therefore, customers who have .NET Framework 3.0 Service Pack 2 installed need to install security updates for .NET Framework 2.0 Service Pack 2.
I have .NET Framework 3.5 Service Pack 1 installed. Do I need to install any additional updates?
This bulletin describes a vulnerability in the .NET Framework 2.0 and the .NET Framework 4.0 feature layers. The .NET Framework 3.5 Service Pack 1 installer chains in both the .NET Framework 2.0 Service Pack 2 setup and the .NET Framework 3.0 Service Pack 2 setup. Therefore, customers who have .NET Framework 3.5 Service Pack 1 installed also need to install security updates for .NET Framework 2.0 Service Pack 2.
I am using an older release of the software discussed in this security bulletin. What should I do?
The affected software listed in this bulletin have been tested to determine which releases are affected. Other releases are past their support life cycle. For more information about the product lifecycle, visit the Microsoft Support Lifecycle Web site.
It should be a priority for customers who have older releases of the software to migrate to supported releases to prevent potential exposure to vulnerabilities. To determine the support lifecycle for your software release, see Select a Product for Lifecycle Information. For more information about service packs for these software releases, see Lifecycle Supported Service Packs.
Customers who require custom support for older software must contact their Microsoft account team representative, their Technical Account Manager, or the appropriate Microsoft partner representative for custom support options. Customers without an Alliance, Premier, or Authorized Contract can contact their local Microsoft sales office. For contact information, visit the Microsoft Worldwide Information Web site, select the country in the Contact Information list, and then click Go to see a list of telephone numbers. When you call, ask to speak with the local Premier Support sales manager. For more information, see the Microsoft Support Lifecycle Policy FAQ.
