FAQ for Win32k Race Condition Vulnerabilities

What is the scope of the vulnerability?
This is an elevation of privilege vulnerability.

What causes the vulnerability?
The vulnerability is caused when the Windows kernel-mode driver improperly handles objects in memory.

What is the Windows kernel-mode driver (win32k.sys)?
Win32k.sys is a kernel-mode device driver and is the kernel part of the Windows subsystem. It contains the window manager, which controls window displays; manages screen output; collects input from the keyboard, mouse, and other devices; and passes user messages to applications. It also contains the Graphics Device Interface (GDI), which is a library of functions for graphics output devices. Finally, it serves as a wrapper for DirectX support that is implemented in another driver (dxgkrnl.sys).

What is the Windows kernel?
The Windows kernel is the core of the operating system. It provides system-level services such as device management and memory management, allocates processor time to processes, and manages error handling.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could gain elevated privileges and read arbitrary amounts of kernel memory.

How could an attacker exploit the vulnerability?
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application designed to increase privileges.

What systems are primarily at risk from the vulnerability
Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What does the update do?
The update addresses the vulnerability by correcting the way that the Windows kernel-mode driver handles objects 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.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was beingexploited?
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security bulletin was originally issued.

Customers are encouraged to upgrade to System Center Configuration Manager. For customers remaining on SMS 2003 Service Pack 3, the Inventory Tool for Microsoft Updates (ITMU) is also an option.

For SMS 2003, the SMS 2003 Inventory Tool for Microsoft Updates (ITMU) can be used by SMS to detect security updates that are offered by Microsoft Update and that are supported by Windows Server Update Services. For more information about the SMS 2003 ITMU, see SMS 2003 Inventory Tool for Microsoft Updates. For more information about SMS scanning tools, see SMS 2003 Software Update Scanning Tools. See also Downloads for Systems Management Server 2003.

System Center Configuration Manager uses WSUS 3.0 for detection of updates. For more information, see System Center.

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.

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.

Supported Security Update Installation 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.

For more information about the terminology that appears in this bulletin, such as *hotfix*, see [Microsoft Knowledge Base Article 824684](http://support.microsoft.com/kb/824684). This security update supports the following setup switches. | Switch | Description | |--------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------| | **/?, /h,** **/help** | Displays help on supported switches. | | **/quiet** | Suppresses the display of status or error messages. | | **/norestart** | When combined with **/quiet**, the system will not be restarted after installation even if a restart is required to complete installation. | | **/warnrestart:<seconds>** | When combined with **/quiet**, the installer will warn the user before initiating restart. | | **/promptrestart** | When combined with **/quiet**, the installer will prompt before initiating restart. | | **/forcerestart** | When combined with **/quiet**, the installer will forcefully close applications and initiate restart. | | **/log:<file name>** | Enables logging to specified file. | | **/extract:<destination>** | Extracts the package contents to the destination folder. | | **/uninstall /kb:<KB Number>** | Uninstalls the security update. | **Note** For more information about the wusa.exe installer, see "Windows Update Stand-alone Installer" in the TechNet article, [Miscellaneous Changes in Windows 7](http://technet.microsoft.com/library/dd871148.aspx). **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 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. #### Windows 8 (all editions) **Reference Table** The following table contains the security update information for this software.
