Vulnerabilities in Microsoft Forefront Unified Access Gateway Could Cause Remote Code Execution (2544641)
Published: October 11, 2011
Version: 1.0
General Information
Executive Summary
This security update resolves five privately reported vulnerabilities in Microsoft Forefront Unified Access Gateway (UAG). The most severe of these vulnerabilities could allow remote code execution if a user visits an affected Web site using a specially crafted URL. However, an attacker would have no way to force users to visit such a Web site. 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.
This security update is rated Important for all supported versions of Microsoft Forefront Unified Access Gateway 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by modifying the way that UAG handles specially crafted requests, modifying the MicrosoftClient.JAR file, and adding exception handling around the null value of the UAG Web server. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

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 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. |

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.
- Click Start, and then click Search.
- In the Search Results pane, click All files and folders under Search Companion.
- In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
- 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. - 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.
