Microsoft Security Bulletin MS12-034 - Critical

Combined Security Update for Microsoft Office, Windows, .NET Framework, and Silverlight (2681578)

Published: May 08, 2012 | Updated: March 06, 2013

Version: 1.6

General Information

Executive Summary

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.

This security update is rated Critical for all supported releases of Microsoft Windows; for Microsoft .NET Framework 4, except when installed on Itanium-based editions of Microsoft Windows; and for Microsoft Silverlight 4 and Microsoft Silverlight 5. This security update is rated Important for Microsoft Office 2003, Microsoft Office 2007, and Microsoft Office 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the most severe of these vulnerabilities by correcting the manner in which affected components handle specially crafted TrueType font files and by correcting the manner in which GDI+ validates specially crafted EMF record types and specially crafted EMF images embedded within Microsoft Office files. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Added an update FAQ entry to explain why Windows Server 2008 customers may not be offered security update KB2658846.

I have a non-vulnerable version of software installed, why am I being offered security update KB2589337?
Some non-affected software, including Microsoft Visio Viewer 2010, contain the vulnerable shared component of Microsoft Office, but because they do not access the vulnerable code, they are not affected. However, since the vulnerable code is present, this update will be offered.

I am running Windows Server 2008. Why am I not being offered security update KB2660649?
Security update package KB2660649 is only applicable on Windows Server 2008 for 32-bit Systems Service Pack 2 and Windows Server 2008 for x64-based Systems Service Pack 2 systems when the optional Desktop Experience feature has been installed and enabled. Windows Server 2008 customers who have installed and enabled the Desktop Experience feature will have the vulnerable component addressed by KB2660649 and will therefore need to install this security update. Customers who have not installed the Desktop Experience feature or who have installed but not enabled the feature will not have the vulnerable component and will therefore not be offered security update package KB2660649.

I am running Windows Server 2008 R2. Why am I not being offered security update KB2660649?

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, see Microsoft Knowledge Base Article 318785.

What is the difference between .NET Framework 4 and .NET Framework 4 Client Profile?
The .NET Framework version 4 redistributable packages are available in two profiles: .NET Framework 4 and .NET Framework 4 Client Profile. The .NET Framework 4 Client Profile is a subset of the .NET Framework 4 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 Client Profile. For more information, see the MSDN article, .NET Framework Client Profile.

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:

Open the Finder
Select the system drive and go to the folder Internet Plug-ins - Library
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
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 4.1.10329 or SilverlightVersion 5.1.10411

The version installed with this security update for Microsoft Silverlight 4 is 4.1.10329. If your Microsoft Silverlight 4 version number is higher than or equal to this version number, your system is not vulnerable. The version installed with this security update for Microsoft Silverlight 5 is 5.1.10411. If your Microsoft Silverlight 5 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.

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.

TrueType Font Parsing Vulnerability - CVE-2011-3402

A remote code execution vulnerability exists in the way that affected components handle a specially crafted TrueType font file. The vulnerability could allow remote code execution if a user opens a specially crafted TrueType font file. 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 impacted than users who operate with administrative user rights.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2011-3402.

Mitigating Factors for TrueType Font Parsing Vulnerability - CVE-2011-3402

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

In a web browsing attack scenario, an attacker could host a website that contains a webpage that is used to exploit this vulnerability. In addition, compromised websites and websites 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 websites. 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 users to the attacker's website.
By default, all supported versions of Microsoft Outlook, Microsoft Outlook Express, and Windows Mail open HTML email messages in the Restricted sites zone, which disables font download by default. If a user clicks a link in an email message, the user could still be vulnerable to exploitation of this vulnerability through the web-based attack scenario. The vulnerability could also be exploited if a user opens an attachment that is sent in an email message.

Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:

Deny access to T2EMBED.DLL

Note Before applying this workaround, users should apply the latest Microsoft security updates. If you are not sure whether your software is up to date, visit Microsoft Update, scan your computer for available updates, and install any high-priority updates that are offered to you.

Note For this workaround, commands for Windows XP and Windows Server 2003 may only work in English language versions of these operating systems.

Note This workaround only mitigates the web-based and file sharing attack scenarios related to the Windows Kernel-Mode Drivers. The local Kernel-Mode Drivers attack scenario, and all other attack scenarios that leverage code in other affected Windows components, Microsoft Office and Microsoft Silverlight will not be mitigated by this workaround.

Note See Microsoft Knowledge Base Article 2639417 to use the automated Microsoft Fix it solution to enable or disable this workaround to deny access to t2embed.dll.

On Windows XP and Windows Server 2003:
- For 32-bit systems, enter the following command at an administrative command prompt:
  
  Echo y| cacls "%windir%\system32\t2embed.dll" /E /P everyone:N
- For 64-bit systems, enter the following commands from an administrative command prompt:
  
  Echo y| cacls "%windir%\system32\t2embed.dll" /E /P everyone:N
  
  Echo y| cacls "%windir%\syswow64\t2embed.dll" /E /P everyone:N
On Windows Vista, Windows 7, Windows Server 2008, and Windows Server 2008 R2:
- For 32-bit systems, enter the following commands at an administrative command prompt:
  
  Takeown.exe /f "%windir%\system32\t2embed.dll"

Workarounds for .NET Framework Buffer Allocation Vulnerability - CVE-2012-0162

Disable XAML browser applications in Internet Explorer

To help protect against this vulnerability, change your settings to prompt before running XAML browser applications (XBAPs) or to disable XBAPs in the Internet and Local intranet security zones as follows:
1. In Internet Explorer, click the Tools menu and then select Internet Options.
2. Click the Security tab, click Internet, and then click Custom level. Under Settings, for Loose XAML, click Prompt or Disable, and then click OK.
3. Click the Security tab, click Internet, and then click Custom level. Under Settings, for XAML browser applications, click Prompt or Disable, and then click OK.
4. Click the Security tab, click Internet, and then click Custom level. Under Settings, for XPS documents, click Prompt or Disable, and then click OK.
5. On the Security tab, click Custom level. Under .NET Framework-reliant components, set Run components not signed with Authenticode to either Prompt or Disable, and then click OK. Repeat this step for Run components signed with Authenticode, and then click OK.
6. Click Local intranet, and then click Custom Level. Repeat steps 3 and 4. If you are prompted to confirm that you want to change these settings, click Yes. Click OK to return to Internet Explorer.
Impact of workaround. Microsoft .NET code will not run in Internet Explorer or will not run without prompting. Disabling Microsoft .NET applications and components in the Internet and Local intranet security zones may cause some websites to work incorrectly. If you have difficulty using a website after you change this setting and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly.

Add sites that you trust to the Internet Explorer Trusted sites zone

After you set Internet Explorer to require a prompt before it runs ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted websites exactly as you do today, while helping to protect you from this attack on untrusted sites. We recommend that you add only sites that you trust to the Trusted sites zone.

To do this, perform the following steps:
1. In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
2. In the Select a Web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
3. If you want to add sites that do not require an encrypted channel, click to clear the Require server verification (https:) for all sites in this zone check box.
4. In the Add this Web site to the zone box, type the URL of a site that you trust, and then click Add.
5. Repeat these steps for each site that you want to add to the zone.
6. Click OK two times to accept the changes and return to Internet Explorer.
Note Add any sites that you trust not to take malicious action on your system. Two in particular that you may want to add are *.windowsupdate.microsoft.com and *.update.microsoft.com. These are the sites that will host the update, and it requires an ActiveX Control to install the update.

How to undo the workaround. Perform the following steps:
1. In Internet Explorer, click the Tools menu, and then select Internet Options.
2. Click the Security tab, click Reset all zones to default level, and then click OK.

FAQ for .NET Framework Buffer Allocation Vulnerability - CVE-2012-0162

What causes the vulnerability?
The vulnerability is caused when the Microsoft .NET Framework improperly allocates a buffer in memory.

What might an attacker use the vulnerability to do?
In the web browsing scenario, an attacker who successfully exploited this vulnerability could obtain the same permissions as the currently logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the 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 impacted than users who operate with administrative user rights.

How could an attacker exploit the vulnerability?
There are two attack scenarios possible for exploiting this vulnerability: a web browsing scenario and a Windows .NET application bypass of Code Access Security (CAS) restrictions. These scenarios are described as follows:

Web browsing attack scenario
An attacker could host a specially crafted website that contains a specially crafted XBAP (XAML browser application) that could exploit this vulnerability and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites 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 websites. 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 in an Instant Messenger message that takes users to the attacker's website. It could also be possible to display specially crafted web content by using banner advertisements or by using other methods to deliver web content to affected systems.
Windows .NET applications attack scenario
This vulnerability could also be used by Windows .NET applications to bypass Code Access Security (CAS) restrictions.

What is an XAML Browser Application (XBAP)?
An XAML browser application (XBAP) combines features of both a web application and a rich-client application. Like web applications, XBAPs can be published to a web server and launched from Internet Explorer. Like rich-client applications, XBAPs can take advantage of the capabilities of Windows Presentation Foundation (WPF). For more information about XBAPs, see MSDN article, Windows Presentation Foundation XAML Browser Applications Overview.

What are .NET Framework Code Access Security (CAS) Restrictions?
The .NET Framework provides a security mechanism called code access security to help protect computer systems from malicious mobile code, to allow code from unknown origins to run with protection, and to help prevent trusted code from intentionally or accidentally compromising security. Code access security (CAS) enables code to be trusted to varying degrees depending on where the code originates and on other aspects of the code's identity. Code access security also enforces the varying levels of trust on code, which minimizes the amount of code that must be fully trusted in order to run. Using code access security can reduce the likelihood that your code will be misused by malicious or error-filled code. For more information on CAS, see the MSDN article, Code Access Security.

What systems are primarily at risk from the vulnerability?
There are two types of systems at risk from this vulnerability, described as follows: systems that are using the web browsing scenario and systems that are using the Windows .NET applications scenario.

Web browsing scenario
Successful exploitation of this vulnerability requires that a user is logged on and is visiting websites using a web browser capable of instantiating XBAPs. Therefore, any systems where a web browser is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability. Servers could be at more risk if administrators allow users to browse and read email on servers. However, best practices strongly discourage allowing this.
Windows .NET applications
Workstations and server that run untrusted Windows .NET applications are also at risk from this vulnerability.

I am running Internet Explorer for Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2. Does this mitigate this vulnerability?
Yes. By default, Internet Explorer on Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2 runs in a restricted mode that is known as Enhanced Security Configuration. Enhanced Security Configuration is a group of preconfigured settings in Internet Explorer that can reduce the likelihood of a user or administrator downloading and running specially crafted web content on a server. This is a mitigating factor for websites that you have not added to the Internet Explorer Trusted sites zone.

What does the update do?
The update addresses the vulnerability by correcting the manner in which the Microsoft .NET Framework allocates buffer space in memory.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

FAQ for Silverlight Double-Free Vulnerability - CVE-2012-0176

What causes the vulnerability?
The vulnerability is caused by Microsoft Silverlight incorrectly freeing memory while rendering specially crafted XAML glyphs.

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.

What are XAML Glyphs?
Windows Presentation Foundation (WPF) provides advanced text support including glyph-level markup with direct access to Glyphs for customers who want to intercept and persist text after formatting. These features provide critical support for the different text rendering requirements in each of the following scenarios: screen display of fixed-format documents, print scenarios, and fixed-format document representation, including clients for previous versions of Windows and other computing devices. For more information, see the MSDN article, Introduction to the GlyphRun Object and Glyphs Element.

What is a "double free" condition?
A double free condition is a condition in which a program is caused to release or free allocated memory more than once. Releasing memory that has already been freed could lead to memory corruption. An attacker could add arbitrary code to memory that is then executed when the corruption occurs. This code could then be executed at a system level of privilege.

Typically, this vulnerability causes a denial of service to occur. However, in some circumstances, it could cause code execution to occur. Because of the unique layout of the memory on each affected system, exploiting this vulnerability on a mass scale could be difficult.

How could an attacker exploit the vulnerability?
An attacker could host a specially crafted website that contains a specially crafted Silverlight application that could exploit this vulnerability and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites 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 websites. 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 in an Instant Messenger message that takes users to the attacker's website. It could also be possible to display specially crafted web content by using banner advertisements or by using other methods to deliver web content to affected systems.

What systems are primarily at risk from the vulnerability?
Successful exploitation of this vulnerability requires that a user is logged on and is visiting websites using a web browser capable of instantiating Silverlight applications. Therefore, any systems where a web browser is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability. Servers could be at more risk if administrators allow users to browse and read email on servers. However, best practices strongly discourage allowing this.

What does the update do?
The update addresses this issue by correcting the manner in which Microsoft Silverlight resets pointers when freeing memory.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

Deployment Information

Installing the Update

When you install this security update, the installer checks whether one or more of the files that are being updated on your system have previously been updated by a Microsoft hotfix.

If you have previously installed a hotfix to update one of these files, the installer copies the RTMQFE, SP1QFE, or SP2QFE files to your system. Otherwise, the installer copies the RTMGDR, SP1GDR, or SP2GDR files to your system. Security updates may not contain all variations of these files. For more information about this behavior, see Microsoft Knowledge Base Article 824994.

For more information about the installer, see Microsoft Knowledge Base Article 832475.

For more information about the terminology that appears in this bulletin, such as hotfix, see Microsoft Knowledge Base Article 824684.

This security update for Windows XP supports the following setup switches.

Switch	Description
/help	Displays the command-line options.
Setup Modes
/passive	Unattended Setup mode. No user interaction is required, but installation status is displayed. If a restart is required at the end of Setup, a dialog box will be presented to the user with a timer warning that the computer will restart in 30 seconds.
/quiet	Quiet mode. This is the same as unattended mode, but no status or error messages are displayed.
Restart Options
/norestart	Does not restart when installation has completed.
/forcerestart	Restarts the computer after installation and force other applications to close at shutdown without saving open files first.
/warnrestart[:x]	Presents a dialog box with a timer warning the user that the computer will restart in x seconds. (The default setting is 30 seconds.) Intended for use with the /quiet switch or the /passive switch.
/promptrestart	Displays a dialog box prompting the local user to allow a restart.
Special Options
/overwriteoem	Overwrites OEM files without prompting.
/nobackup	Does not back up files needed for uninstall.
/forceappsclose	Forces other programs to close when the computer shuts down.
/log:path	Allows the redirection of installation log files.
/integrate:path	Integrates the update into the Windows source files. These files are located at the path that is specified in the switch.
/extract[:path]	Extracts files without starting the Setup program.
/ER	Enables extended error reporting.
/verbose	Enables verbose logging. During installation, creates %Windir%\CabBuild.log. This log details the files that are copied. Using this switch may cause the installation to proceed more slowly.

Note You can combine these switches into one command. For backward compatibility, the security update also supports the setup switches that the earlier version of the Setup program uses. For more information about the supported installation switches, see Microsoft Knowledge Base Article 262841.

This security update for Microsoft .NET Framework supports the following setup switches.

Verifying That the Update Has Been Applied

Microsoft Baseline Security Analyzer

To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the section, Detection and Deployment Tools and Guidance, earlier in this bulletin for more information.
File Version Verification

Because there are several editions of Microsoft Windows, the following steps may be different on your system. If they are, see your product documentation to complete these steps.
1. Click Start, and then click Search.
2. In the Search Results pane, click All files and folders under Search Companion.
3. In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
4. In the list of files, right-click a file name from the appropriate file information table, and then click Properties.
  Note Depending on the edition of the operating system, or the programs that are installed on your system, some of the files that are listed in the file information table may not be installed.
5. On the Version tab, determine the version of the file that is installed on your system by comparing it to the version that is documented in the appropriate file information table.
  Note Attributes other than the file version may change during installation. Comparing other file attributes to the information in the file information table is not a supported method of verifying that the update has been applied. Also, in certain cases, files may be renamed during installation. If the file or version information is not present, use one of the other available methods to verify update installation.
Registry Key Verification

You may also be able to verify the files that this security update has installed by reviewing the registry keys listed in the Reference Table in this section.

These registry keys may not contain a complete list of installed files. Also, these registry keys may not be created correctly when an administrator or an OEM integrates or slipstreams this security update into the Windows installation source files.

Verifying That the Update Has Been Applied

Microsoft Baseline Security Analyzer

To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the section, Detection and Deployment Tools and Guidance, earlier in this bulletin for more information.
File Version Verification

Because there are several editions of Microsoft Windows, the following steps may be different on your system. If they are, see your product documentation to complete these steps.
1. Click Start and then enter an update file name in the Start Search box.
2. When the file appears under Programs, right-click the file name and click Properties.
3. On the General tab, compare the file size with the file information tables provided in the bulletin KB article.
  Note Depending on the edition of the operating system, or the programs that are installed on your system, some of the files that are listed in the file information table may not be installed.
4. You can also click the Details tab and compare information, such as file version and date modified, with the file information tables provided in the bulletin KB article.
  Note Attributes other than the file version may change during installation. Comparing other file attributes to the information in the file information table is not a supported method of verifying that the update has been applied. Also, in certain cases, files may be renamed during installation. If the file or version information is not present, use one of the other available methods to verify update installation.
5. Finally, you can also click the Previous Versions tab and compare file information for the previous version of the file with the file information for the new, or updated, version of the file.
