A remote code execution vulnerability exists in the way that GDI handles integer calculations. The vulnerability could allow remote code execution if a user opens a specially crafted EMF or WMF image file. 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.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2008-1083.

Mitigating Factors for GDI Heap Overflow Vulnerability - CVE-2008-1083

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.

  • 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 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 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.

Workarounds for GDI Heap Overflow Vulnerability - CVE-2008-1083

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.

  • Turn off metafile processing by modifying the registry

    Customers who have applied MS07-017 or customers using Windows Vista or Windows Server 2008 can disable metafile processing by modifying the registry. This setting will help protect the affected system from attempts to exploit this vulnerability.

    To modify the 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.
    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_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\GRE_Initialize
    3. On the Edit menu, point to New, and then click DWORD.
    4. Type DisableMetaFiles, and then press ENTER.
    5. On the Edit menu, click Modify to modify the DisableMetaFiles registry entry.
    6. In the Value data box, type 1, and then click OK.
    7. Exit Registry Editor.
    8. Reboot the computer.

    Impact of workaround.Turning off processing of metafiles may cause the appearance of software or system components to decrease in quality. Turning off processing of metafiles may also cause the software or system components to fail completely. It has been identified to have a potential significant functionality impact and should be evaluated and tested carefully to determine its applicability.

    Examples include the following:

    • You cannot print on the computer.
    • Some applications on the computer may be unable to display Clipart.
    • Some scenarios that involve OLE rendering may break. Especially, it occurs when the object server is not active.

    For more information on this setting please read Microsoft Knowledge Base Article 941835.

    Managed Deployment Script:

    1. Save the following to a file with a .REG extension (e.g. Disable_MetaFiles.reg):

      Windows Registry Editor Version 5.00

      [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\GRE_Initialize]
      "DisableMetaFiles"=dword:00000001
    2. Run the above registry script on the target machine with the following command from an administrator (on Vista, an elevated administrator) command prompt:

      Regedit.exe /s Disable_MetaFiles.reg
    3. Reboot the computer.

    How to undo the workaround:

    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_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\GRE_Initialize

FAQ for GDI Heap Overflow Vulnerability - CVE-2008-1083

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. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

What causes the vulnerability? 
The vulnerability is caused by a buffer overflow when GDI improperly processes a malformed header in a specially crafted EMF or WMF image file.

What is GDI? 
The Microsoft Windows graphics device interface (GDI) enables applications to use graphics and formatted text on both the video display and the printer. Windows-based applications do not access the graphics hardware directly. Instead, GDI interacts with device drivers on behalf of applications. For more information about GDI, visit the Windows GDI Start Page.

What are Windows Metafile (WMF) and Enhanced Metafile (EMF) image formats?
A WMF image is a 16-bit metafile format that can contain both vector information and bitmap information. It is optimized for the Windows operating system.

An EMF image is a 32-bit format that can contain both vector information and bitmap information. This format is an improvement over the Windows Metafile Format and contains extended features.

For more information about image types and formats, see Microsoft Knowledge Base Article 320314. Additional information about these file formats is also available at the MSDN Library Web Site.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could run arbitrary code. 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 image file.

In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially-crafted EMF or WMF image file or an Office document with a specially-crafted EMF or WMF image file embedded in it to the user and by convincing the user to open the document or view the email containing the specially crafted image file.

In a Web-based attack scenario, an attacker would have to host a Web site that contains an EMF or WMF image file 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? 
All currently supported Windows systems are at risk.

What does the update do? 
The update removes the vulnerability by modifying the way GDI performs integer calculations to prevent a heap overflow condition.

/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.
