Microsoft Update, Windows Update, the Microsoft Baseline Security Analyzer (MBSA), and Microsoft Systems Management Server (SMS) already correctly offer KB941568 to customers that have DirectX 9.0a installed. Customers with DirectX 9.0a installed should apply the update to remain secure.

Why was this bulletin revised on January 23, 2008? 
This bulletin was revised to add DirectX 9.0 and 9.0b as affected products. Microsoft Update, Windows Update, the Microsoft Baseline Security Analyzer (MBSA), and Microsoft Systems Management Server (SMS) already correctly offer KB941568 to customers that have DirectX 9.0 and 9.0b installed. Customers with DirectX 9.0 and 9.0b installed should apply the update to remain secure.

Why does this update address several reported security vulnerabilities? 
This update contains support for several vulnerabilities because the modifications that are required to address these issues are located in related files. Instead of having to install several updates that are almost the same, customers need to install this update only.

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. To determine the support life cycle for your software release, visit Microsoft Support Lifecycle.

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. For more information about the Windows Product Lifecycle, visit Microsoft Support Lifecycle. For more information about the extended security update support period for these software versions or editions, visit Microsoft Product Support Services.

Customers who require custom support for older releases 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 Microsoft Worldwide Information, select the country, 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 Windows Operating System Product Support Lifecycle FAQ.

Does this update contain any security-related changes to functionality? 
Yes. Besides the changes that are listed in the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the bulletin section, Vulnerability Information, this update includes defense-in-depth changes to DirectX.

* The update for DirectX 9.0 also applies to DirectX 9.0a, DirectX 9.0b, and DirectX 9.0c.

A remote code execution vulnerability exists in the way DirectX handles supported format files. This vulnerability could allow code execution if a user opened a specially crafted file. If a user is logged on with administrative user rights, 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-2007-3901.

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

•	The vulnerability cannot be exploited automatically through e-mail when a user views or previews e-mail messages. For an attack to be successful, a user must open an attachment that is sent in an e-mail message.

Top of section

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:

•

Modify the Access Control List for quartz.dll On Windows XP (all editions), run the following command from a command prompt: Echo y| Cacls.exe %WINDIR%\SYSTEM32\QUARTZ.DLL /E /P everyone:N On Windows Vista (all editions), run the following command from an elevated command prompt: Takeown.exe /f %WINDIR%\SYSTEM32\QUARTZ.DLL Icacls.exe %WINDIR%\SYSTEM32\QUARTZ.DLL /save %TEMP%\QUARTZ_ACL.TXT Icacls.exe %WINDIR%\SYSTEM32\QUARTZ.DLL /deny everyone:(F) Impact of workaround: WAV and AVI files will fail to play in DirectX-enabled applications on Windows Vista. All files will fail to play in DirectX-enabled applications on Windows XP. How to undo the workaround: On Windows XP (all editions), run the following command from a command prompt: Cacls.exe %WINDIR%\SYSTEM32\QUARTZ.DLL /E /R everyone On Windows Vista (all editions), run the following command from an elevated command prompt: Icacls.exe %WINDIR%\SYSTEM32\QUARTZ.DLL /grant everyone:(F) Icacls.exe %WINDIR%\SYSTEM32 /restore %TEMP%\QUARTZ_ACL.TXT

•

Unregister the quartz.dll Regsvr32.exe –u %WINDIR%\SYSTEM32\QUARTZ.DLL Impact of workaround: WAV and AVI files will fail to play in DirectX-enabled applications on Windows Vista. All files will fail to play in DirectX-enabled applications on Windows XP. How to undo the workaround: Run the following command from an elevated command prompt: Regsvr32.exe %WINDIR%\SYSTEM32\QUARTZ.DLL

What is the scope of the vulnerability? 
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

What causes the vulnerability? 
Microsoft DirectShow, an intergraded technology of DirectX, does not perform sufficient parsing of the parameters of Synchronized Accessible Media Interchange (SAMI) file types.

What is DirectShow? 
Microsoft DirectShow is used for streaming media on Microsoft Windows operating systems. DirectShow is used for high-quality capture and playback of multimedia streams. It automatically detects and uses video and audio acceleration hardware when available, but also supports systems without acceleration hardware. DirectShow is also integrated with other DirectX technologies. Some examples of applications that you can create using DirectShow include DVD players, video editing applications, AVI to ASF converters, MP3 players, and digital video capture applications.

What is DirectX? 
Microsoft DirectX is a feature of the Windows operating system. It is used for streaming media on Microsoft Windows operating systems to enable graphics and sound when playing games or watching video.

What might an attacker use the vulnerability to do? 
If a user is logged on with administrative user rights, 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.

How could an attacker exploit the vulnerability? 
Exploitation of this vulnerability would require a user to open a specially crafted format file. However, since the vulnerability is in the streaming component of Microsoft Windows, attacks can be launched from a specially crafted Web site or any application that delivers Web content.

What systems are primarily at risk from the vulnerability? 
This vulnerability requires that a user is logged on and opens the specially crafted file. Workstations and terminal servers are primarily at risk. Servers could be at more risk if users who should not have sufficient administrative permissions are given the ability to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What does the update do?
The update removes the vulnerability by increasing the validation that the DirectX parser performs on supported file types.

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

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.

A remote code execution vulnerability exists in the way DirectX handles WAV and AVI format files. This vulnerability could allow code execution if a user visits a specially crafted Web site or opens an e-mail message with specially crafted content. If a user is logged on with administrative user rights, 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-2007-3895.

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-based attack scenario, an attacker could host a Web site that contains a Web page that is used to exploit this vulnerability. In addition, compromised Web sites and Web sites 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 Web sites. Instead, an attacker would have to convince 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.
•	An attacker who successfully exploited this vulnerability could gain the same user rights as the local 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.
•	In an e-mail-based attack of this exploit, customers who read e-mail in plain text are at less risk from this vulnerability.

/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	Display 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

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 versions of Microsoft Windows, the following steps may be different on your computer. 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 version of the operating system or programs installed, 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 computer 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.
