Why was this bulletin revised on December 9, 2008?
This bulletin was revised to communicate the removal of the Windows Server 2003 package due to issues unrelated to the stability of the update or the security of the intended target systems. Customers who have already successfully applied this update need not take any action. Windows Server 2003 customers who have not applied this update and are concerned with this issue should apply the latest service pack. The applicability of this bulletin on other Windows operating systems has not changed.

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 can install only this update.

What updates does this release replace?
This security update replaces several prior security bulletins. The security bulletin IDs and operating systems that are affected are listed in the following table.

I am still using Windows XP, but extended security update support ended on September 30th, 2004. However, this bulletin has a security update for this operating system version. Why is that?

The original version of Windows XP, commonly known as Windows XP Gold or Windows XP Release to Manufacturing (RTM) version, reached the end of its extended security update support life cycle on September 30, 2004. However, the end-of-life occurred very recently. In this case, the majority of the steps that are required to address this vulnerability were completed before this date. Therefore, we have decided to release a security update for this operating system version as part of this security bulletin.

We do not anticipate doing this for future vulnerabilities that may affect this operating system version, but we reserve the right to produce updates and to make these updates available when necessary. It should be a priority for customers who have this operating system version to migrate to supported operating system versions to prevent potential exposure to vulnerabilities. For more information about the Windows Service Pack Product Life Cycle, visit the Microsoft Support Lifecycle Web site. For more information about the Windows Product Life Cycle, visit the Microsoft Support Lifecycle Web site.

For more information, see the Windows Operating System FAQ.

I am still using Microsoft Windows NT 4.0 Workstation Service Pack 6a or Windows 2000 Service Pack 2, but extended security update support ended on June 30, 2004. What should I do?
Windows NT 4.0 Workstation Service Pack 6a and Windows 2000 Service Pack 2 have reached the end of their life cycles as previously documented, and Microsoft extended this support to June 30, 2004.

It should be a priority for customers who have these operating system versions to migrate to supported versions to prevent potential exposure to vulnerabilities. For more information about the Windows Product Life Cycle, visit the following Microsoft Support Lifecycle Web site. For more information about the extended security update support period for these operating system versions, visit the following Microsoft Product Support Services Web site.

Workarounds for Window Management Vulnerability - CAN-2004-0207:

None.

FAQ for Window Management Vulnerability - CAN-2004-0207:

What is the scope of the vulnerability?
This is a local privilege elevation vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system, including installing programs; viewing, changing, or deleting data; or creating new accounts that have full privileges.

What causes the vulnerability?
Several Window Management API functions allow programs to change the properties of other programs that are running at a higher level of privilege. Programs should be limited to changing the properties of other programs that are running at the same level of privilege. The properties of the program that is running at a higher level of privilege could be changed in such a way that the change could cause an elevation of privilege for the locally logged on user.

What are the Window Management application programming interface functions?
The Windows graphical user interface (GUI) allows programs to change various properties that define that program such as the size of the window or the name of the program. The Window Management API functions are the components of the operating system that programs use to change these properties. For more information about the components that are used to build Windows programs, visit the MSDN Web site.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could take complete control of the affected system.

Who could exploit the vulnerability?
To exploit the vulnerability, an attacker must be able to log on locally to a system and run a program.

MS04-011 helps protect against the vulnerability that is discussed in that bulletin, but does not address this new vulnerability. This update does not replace MS04-011. You must install this update and the update that is provided as part of the MS04-011 security bulletin to help protect your system against both vulnerabilities.

Graphics Rendering Engine Vulnerability - CAN-2004-0209:

A remote code execution vulnerability in the rendering of Windows Metafile (WMF) and Enhanced Metafile (EMF) image formats that could allow remote code execution on an affected system. Any program that renders WMF or EMF images on the affected systems could be vulnerable to this attack. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Mitigating Factors for Graphics Rendering Engine Vulnerability - CAN-2004-0209:

  • The vulnerability could be exploited by an attacker who persuaded a user to open a specially crafted file or to view a folder that contains the specially crafted image. There is no way for an attacker to force a user to open a malicious file, except potentially through previewing an email message.
  • 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 persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site.
  • Windows XP Service Pack 2 is not affected by this vulnerability.

Workarounds for Graphics Rendering Engine Vulnerability - CAN-2004-0209:

Microsoft has tested the following workarounds. While these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified below.

  • Read e-mail messages in plain text format if you are using Outlook 2002 or later, or Outlook Express 6 SP1 or later, to help protect yourself from the HTML e-mail attack vector.

    Microsoft Outlook 2002 users who have applied Office XP Service Pack 1 or later and Microsoft Outlook Express 6 users who have applied Internet Explorer 6 Service Pack 1 can enable this setting and view e-mail messages that are not digitally signed or e-mail messages that are not encrypted in plain text only.

    Digitally signed e-mail messages or encrypted e-mail messages are not affected by the setting and may be read in their original formats. For more information about enabling this setting in Outlook 2002, see Microsoft Knowledge Base Article 307594.

    For information about this setting in Outlook Express 6, see Microsoft Knowledge Base Article 291387.

    Impact of Workaround: E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. In addition:

    • The changes are applied to the preview pane and to open messages.
    • Pictures become attachments so that they are not lost.
      Note Manually viewing these pictures could allow remote code execution if you are using a vulnerable application or operating system.
    • Because the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.

FAQ for Graphics Rendering Engine Vulnerability - CAN-2004-0209:

What is the scope of the vulnerability?
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could remotely take complete control of an affected system, including installing programs; viewing, changing, or deleting data; or creating new accounts that have full privileges. This vulnerability could also be used to attempt to perform a local elevation of privilege or a remote denial of service.

What causes the vulnerability?
An unchecked buffer in the way that the Graphics Rendering Engine processes Windows Metafile (WMF) and Enhanced Metafile (EMF) image formats.

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 take complete control of an affected system, including installing programs; viewing, changing, or deleting data; or creating new accounts that have full privileges.

How could an attacker exploit this vulnerability?
Any program that renders the affected image types could be vulnerable to this attack. Here are some examples:

  • An attacker could host a malicious Web site that is designed to exploit this vulnerability through Internet Explorer and then persuade a user to view the Web site.
  • An attacker could create an HTML e-mail message that has a specially crafted image attached. The specially crafted image could be designed to exploit this vulnerability through Microsoft Outlook or through Outlook Express 6. An attacker could persuade the user to view the HTML e-mail message.
  • An attacker could embed a specially crafted image in an Office document and then persuade the user to view the document.
  • An attacker could add a specially crafted image to the local file system or onto a network share and then persuade the user to preview the folder.
  • An attacker could locally log on to the system. An attacker could then run a specially-designed program that could exploit the vulnerability, and thereby gain complete control over the affected system.

An attacker could also access the affected component through another vector. For example, an attacker could log on to the system interactively or by using another program that passes parameters to the vulnerable component (locally or remotely). To locally exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially-designed application that could exploit the vulnerability, and thereby gain complete control over the affected system.

What systems are primarily at risk from the vulnerability?
The vulnerability could be exploited on the affected systems by an attacker who persuaded a user to open a specially crafted file or to view a folder that contains the specially crafted image. There is no way for an attacker to force a user to open a specially crafted file, except potentially through previewing an email message.

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 persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site.

Could the vulnerability be exploited over the Internet?
Yes. An attacker could attempt to exploit this vulnerability over the Internet.

What does the update do?
The update removes the vulnerability by modifying the way that the Graphics Rendering Engine processes Windows Metafile (WMF) and Enhanced Metafile (EMF) image formats.

  • Microsoft Baseline Security Analyzer

    To verify that a security update is installed on an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. This tool allows administrators to scan local and remote systems for missing security updates and for common security misconfigurations. For more information about MBSA, visit the Microsoft Baseline Security Analyzer Web site.

  • File Version Verification

    Note 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 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 the update installation. 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 following registry keys.

Verifying Update Installation

  • Microsoft Baseline Security Analyzer

    To verify that a security update is installed on an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. This tool allows administrators to scan local and remote systems for missing security updates and for common security misconfigurations. For more information about MBSA, visit the Microsoft Baseline Security Analyzer Web site.

  • File Version Verification

    Note 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 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 the update installation. 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 following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Hotfix\KB840987\File 1

    Note This registry key may not contain a complete list of installed files. Also, this registry key may not be created correctly when an administrator or an OEM integrates or slipstreams the 840987 security update into the Windows installation source files.

Security Resources:

Software Update Services:

By using Microsoft Software Update Services (SUS), administrators can quickly and reliably deploy the latest critical updates and security updates to Windows 2000 and Windows Server 2003-based servers, and to desktop systems that are running Windows 2000 Professional or Windows XP Professional.

For more information about how to deploy this security update with Software Update Services, visit the Software Update Services Web site.

Systems Management Server:

Microsoft Systems Management Server (SMS) delivers a highly-configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. For more information about how administrators can use SMS 2003 to deploy security updates, see the SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack to help deploy security updates. For information about SMS, visit the SMS Web site.

Note SMS uses the Microsoft Baseline Security Analyzer and the Microsoft Office Detection Tool to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to target updates to specific systems. For more information about this procedure, see the following Web site. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
