The Office component discussed in this bulletin is part of the Office Suite that I have installed on my system; however, I did not choose to install this specific component. Will I be offered this update? 
Yes, if the version of the Office Suite installed on your system shipped with the component discussed in this bulletin, the system will be offered updates for it whether the component is installed or not. The detection logic used to scan for affected systems is designed to check for updates for all components that shipped with the particular Office Suite and offer the updates to a system. Users who choose not to apply an update for a component that is not installed, but is included in the version of the Office Suite, will not increase the security risk of that system. However, users who do choose to install the update will not have a negative impact on the security or performance of a system. For more information on this issue, please see Microsoft Knowledge Base Article 830335.

I use Microsoft Office 2003 Service Pack 2. Are any additional security features included in this update? 
Yes, as part of the servicing model for Microsoft Office 2003, when users of Microsoft Office 2003 Service Pack 2 install this update, their systems will be upgraded to security functionality that was initially released with Microsoft Office 2003 Service Pack 3. All updates released after January 1, 2008 for Microsoft Office 2003 Service Pack 2 will include these security features, which were introduced in Microsoft Office 2003 Service Pack 3. We have thoroughly tested this update, but as with all updates, we recommend that users perform testing appropriate to the environment and configuration of their systems. For more information on this issue, please see Microsoft Knowledge Base Article 951646.

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 the following Microsoft Support Lifecycle. For more information about the extended security update support period for these software releases, visit the Microsoft Product Support Services Web site.

Customers who require custom support for older software 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 the Microsoft Worldwide Information Web site, 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.

Why is this update Critical for Word 2000 but only Important for all other affected versions of Word? 
Users who are running Office XP (Word 2002) and beyond have a built-in feature that will prompt a user to Open, Save, or Cancel before opening a document. This mitigating factor reduces the vulnerability from Critical to Important because the vulnerability requires more than a single user action to complete the exploit.

I use Microsoft Office 2003 Service Pack 3. Why am I still being offered this update? 
Microsoft Office 2003 Service Pack 3 is not impacted by the security vulnerabilities documented in this bulletin. However, users will still be offered this update because the updated files for Microsoft Office 2003 Service Pack 3 are newer (with higher version numbers) than the files that were delivered with Microsoft Office 2003 Service Pack 3. We have thoroughly tested this update, but as with all updates, we recommend that users perform testing appropriate to their environment and configurations of their systems.

Does the offer to update Microsoft Office 2003 Service Pack 3 constitute an issue in the Microsoft update mechanism? 
No, the update mechanism is functioning correctly in that the update package has a newer version and thus, offers the update.

What is included in the Microsoft Office Service Pack 3 update that causes the higher version of the update files? 
The update files include changes to support stability changes in Microsoft Office 2003 Service Pack 3 and additional changes to support corporate environment changes. We have thoroughly tested this update, but as with all updates, we recommend that users perform testing appropriate to their environment and configurations of their systems.

A remote code execution vulnerability exists in the way that Word handles specially crafted Word files. The vulnerability could allow remote code execution if a user opens a specially crafted Word file that includes a malformed value. 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-2008-0109.

Mitigating Factors for Word Memory Corruption Vulnerability – CVE-2008-0109

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:

  • The vulnerability cannot be exploited automatically through e-mail. For an attack to be successful, a user must open an attachment that is sent in an e-mail message.
  • 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.
  • 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.
  • Users who have installed and are using the Office Document Open Confirmation Tool for Office 2000 will be prompted with Open, Save, or Cancel before opening a document. The features of the Office Document Open Confirmation Tool are incorporated in Office XP and later editions of Office.

Workarounds for Word Memory Corruption Vulnerability – CVE-2008-0109

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:

  • Use the Microsoft Office Isolated Conversion Environment (MOICE) when opening files from unknown or un-trusted sources

    The Microsoft Office Isolated Conversion Environment (MOICE) when added to the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats is used to more securely open Word, Excel, and PowerPoint binary format files.

    To install MOICE, you must have Office 2003 or 2007 Office installed.

    To install MOICE, you must have the Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. The compatibility pack is available as a free download from the Microsoft Download Center:

    Download the FileFormatConverters.exe package now

    MOICE requires all updates that are recommended for all Office programs. Visit Microsoft Update to install all recommended updates:

    http://update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us

    To enable MOICE, change the registered handle for the .doc file format. The following table describes the command to enable or to disable MOICE for the .doc file format:

Command to use to enable MOICE to be the registered handlerCommand to use to disable MOICE as the registered handler
ASSOC .doc=oice.word.documentASSOC .doc=Word.Document.8

For more information on MOICE, see the following Microsoft Knowledge Base Article 935865.

Impact of Workaround: Office 2003 and earlier formatted documents that are converted to the 2007 Microsoft Office System Open XML format by MOICE will not retain macro functionality. Additionally, documents with passwords or that are protected with Digital Rights Management cannot be converted.

  • Use Microsoft Office File Block policy to prevent the opening of Office 2003 and earlier documents from unknown or untrusted sources and locations.

    The following registry scripts can be used to set the File Block policy.

    Note Modifying the Registry incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from incorrect modification of the Registry can be solved. Modify the Registry at your own risk.

    For Office 2003

    Windows Registry Editor Version 5.00

    [HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\FileOpenBlock]

    "BinaryFiles"=dword:00000001

    Note In order to use 'FileOpenBlock' with Office 2003, all of the latest Office 2003 security updates as of May 2007 must be applied.

    Impact of Workaround: Users who have configured the File Block policy and have not configured a special “exempt directory” as discussed in Microsoft Knowledge Base Article 922848 will be unable to open Office 2003 files or earlier versions in Office 2003 or 2007 Microsoft Office System.

    Rollback

    Windows Registry Editor Version 5.00

    [HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\FileOpenBlock]

    "BinaryFiles"=dword:00000000

  • Do not open or save Microsoft Office files that you receive from untrusted sources or that you receive unexpectedly from trusted sources. This vulnerability could be exploited when a user opens a specially crafted file.

FAQ for Word Memory Corruption Vulnerability – CVE-2008-0109

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 memory calculation error when parsing a specially crafted Word file. The error may corrupt system memory in such a way that an attacker could execute arbitrary code.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could take complete control of an affected system. If a user is logged on with administrative user rights, an attacker could take complete control of the 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.

How could an attacker exploit the vulnerability? 
This vulnerability requires that a user open a specially crafted Word file with an affected version of Microsoft Word.

In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially-crafted Word file 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 a Word 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.

This security update supports the following setup switches.

Supported Security Update Installation Switches
SwitchDescription
/q Specifies quiet mode, or suppresses prompts, when files are being extracted.
/q:u Specifies user-quiet mode, which presents some dialog boxes to the user.
/q:a Specifies administrator-quiet mode, which does not present any dialog boxes to the user.
/t:path Specifies the target folder for extracting files.
/c Extracts the files without installing them. If /t:path is not specified, you are prompted for a target folder.
/c:path Overrides the install command that is defined by author. Specifies the path and name of the Setup.inf or .exe file.
/r:n Never restarts the system after installation.
/r:I Prompts the user to restart the system if a restart is required, except when used with /q:a.
/r:a Always restarts the system after installation.
/r:s Restarts the system after installation without prompting the user.
/n:v No version checking - Install the program over any earlier version.

Note You can combine these switches into one command. For backward compatibility, the security update also supports the setup switches that the earlier version of the Setup program uses. For more information about the supported installation switches, see Microsoft Knowledge Base Article 262841.

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 “Microsoft baseline Security Analyzer” heading under the section, Microsoft Detection and Deployment Tools and Guidance.

  • File Version Verification

    Because there are several versions and 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 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 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.
