A remote code execution vulnerability exists in the way Microsoft DirectShow handles supported format files. This vulnerability could allow code execution if a user opened a specially crafted MJPEG 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-2009-0084.

Mitigating Factors for MJPEG Decompression Vulnerability - CVE-2009-0084

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 would have to host a Web site that contains a Web page that is used to exploit this vulnerability. An attacker would have no way to force users to visit a malicious Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's Web site. After they click the link, they would be prompted to perform several actions. An attack could only occur after they performed these actions.
  • 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.

Workarounds for MJPEG Decompression Vulnerability - CVE-2009-0084

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:

  • Disable the decoding of MJPEG content in Quartz.dll

    To modify the registry key, follow these steps:

    Note Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.

    Using the Interactive Method

    1. Click Start, click Run, type Regedit in the Open box, and then click OK.
    2. Locate and then click the following registry subkey: HKEY_CLASSES_ROOT\CLSID\{301056D0-6DFF-11D2-9EEB-006008039E37}
    3. Click the File menu and select Export.
    4. In the Export Registry File dialog box, enter MJPEG_Decoder_Backup.reg and click Save.

      Note This will create a backup of this registry key in the My Documents folder by default.
    5. Press the Delete key on the keyboard to delete the registry key. When prompted to delete the registry key via the Confirm Key Delete dialog box, click Yes.

    Using a Managed Deployment Script

    1. Create a backup copy of the registry keys by using a managed deployment script that contains the following commands:
      Regedit.exe /e MJPEG_Decoder_Backup.reg HKEY_CLASSES_ROOT\CLSID\{301056D0-6DFF-11D2-9EEB-006008039E37}
    2. Next, save the following to a file with a .REG extension, such as Disable_MJPEG_Decoder.reg:
      Windows Registry Editor Version 5.00
      [-HKEY_CLASSES_ROOT\CLSID\{301056D0-6DFF-11D2-9EEB-006008039E37}]
    3. Run the above registry script on the target machine with the following command from an elevated command prompt:
      Regedit.exe /s Disable_MJPEG_Decoder.reg

    Impact of workaround. MJPEG content playback will be disabled.

    How to undo the workaround.

    Using the Interactive Method

    1. Click Start, click Run, type Regedit in the Open box, and then click OK.
    2. Click the File menu and select Import.
    3. In the Import Registry File dialog box, select MJPEG_Decoder_Backup.reg and click Open.

    Using a Managed Deployment Script

    Restore the original state by running the following command:
    Regedit.exe /s MJPEG_Decoder_Backup.reg

  • Unregister quartz.dll

    To unregister this DLL, run the following command from an elevated command prompt.

    For 32-bit Windows systems:

    Regsvr32.exe –u %WINDIR%\system32\quartz.dll

    For 64-bit Windows systems:

    Regsvr32.exe –u %WINDIR%\syswow64\quartz.dll

    Impact of workaround. Windows Media Player will not be able to play .AVI or .WAV files.

    How to undo the workaround.

    For 32-bit Windows systems:

    Regsvr32.exe %WINDIR%\system32\quartz.dll

    For 64-bit Windows systems:

    Regsvr32.exe %WINDIR%\syswow64\quartz.dll

FAQ for MJPEG Decompression Vulnerability - CVE-2009-0084

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? 
The Microsoft DirectShow component does not properly handle specially crafted compressed files.

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 is DirectShow? 
DirectX consists of a set of low-level Application Programming Interfaces (APIs) used by Windows programs for multimedia support. Within DirectX, the DirectShow technology performs client-side audio and video sourcing, manipulation and rendering.

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 an MJPEG file? 
An MJPEG file is a media file where a number of JPEG images are connected together to create a video stream. The MJPEG video stream can then be inserted into an AVI or other common video formatted file.

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? 
This vulnerability requires that a user open a specially crafted MJPEG file or receive specially crafted streaming content from a Web site or any application that delivers Web content.

In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a media file with a specially crafted MJPEG file embedded in it to the user and by convincing the user to open the file.

In a Web-based attack scenario, an attacker would have to host a Web site that contains specially crafted content that is used to attempt to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes them to the attacker's site.

What systems are primarily at risk from the vulnerability? 
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 addresses the issue by correcting the way that DirectShow decompresses media files.

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.

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, visit the Microsoft TechNet Web site.

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.

/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

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.
