A remote code execution vulnerability exists in the way that Windows Movie Maker handles specially crafted project files. 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.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-2564.

Mitigating Factors for Movie Maker Memory Corruption Vulnerability - CVE-2010-2564

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.
  • The specially crafted file could be sent as an e-mail attachment, but the attacker would have to convince the user to open the attachment in order to exploit the vulnerability.
  • 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 Movie Maker Memory Corruption Vulnerability - CVE-2010-2564

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:

  • Remove the Movie Maker .MSWMM file association

    Note See Microsoft Knowledge Base Article 981997 to use the automated Microsoft Fix it solution to enable or disable this workaround. This Fix it solution deploys the workaround, and thus has the same user impact. We recommend that administrators review the KB article closely prior to deploying this Fix it solution.

    Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use the 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.

    Note We recommend backing up the registry before you edit it.

    To remove the Movie Maker .MSWMM file association, follow these steps:

    Interactive Method

    1. Click Start, click Run, type regedit, and then click OK.
    2. Expand HKEY_CLASSES_ROOT, click on .MSWMM, and then click the File menu and select Export.
    3. In the Export Registry File dialog box, type MSWMM file association registry backup.reg and click Save. This will create a backup of this registry key in the 'My Documents' folder by default.
    4. Press the Delete key on the keyboard to delete the registry key. When prompted to delete the registry value, click Yes.

    Managed Deployment Script

    1. Make a backup copy of the registry key using the following command:

      Regedit.exe /e MSWMM_registry_backup.reg HKEY_CLASSES_ROOT\.MSWMM
    2. Save the following to a file with a .REG extension (i.e., Delete_MSWMM_file_association.reg):

      Windows Registry Editor Version 5.00

      [-HKEY_CLASSES_ROOT\.MSWMM]
    3. Run the registry script created in step 2 on the target machine with the following command:

      Regedit.exe /s Delete_MSWMM_file_association.reg

    Impact of workaround. This workaround removes the .MSWMM file association. Double-clicking an MSWMM file will no longer launch Windows Movie Maker.

    How to undo the workaround. Restore the registry key by using Regedit to restore the settings saved in the .REG file.
