A remote code execution vulnerability exists in the way that text converters in WordPad and Microsoft Office process memory when a user opens a specially crafted Word 6 file that includes malformed data.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2009-0087.

Mitigating Factors for WordPad and Office Text Converter Memory Corruption Vulnerability - CVE-2009-0087

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 site. After they click the link, they would be prompted to perform several actions. An attack could only occur after they performed these actions.
  • The vulnerability could not 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.
  • An attacker who successfully exploited this vulnerability could gain the same privileges as the user. Users whose accounts are configured to have fewer privileges on the system could be less impacted than users who operate with administrative privileges.
  • All supported editions of Windows XP and Windows Server 2003 are at a reduced risk to this vulnerability because the affected component is disabled by default. These operating systems are only vulnerable if an administrator has manually enabled the affected component. All supported editions of Windows Vista and Windows Server 2008 do not contain the affected component and are also unaffected.

    Microsoft Windows 2000 Service Pack 4 systems are more at risk because the converter is still active in a default installation. However, on Microsoft Windows 2000 Service Pack 4 systems that have applied the MS04-041 update, the Word for Windows 6.0 converter will be disabled by default.
  • Users who have installed and are using the Office Document Open Confirmation Tool for Office 2000 will be prompted with Open, Save, or Cancelbefore opening a document. The features of the Office Document Open Confirmation Tool are incorporated in Office XP and later editions of Office.

Workarounds for WordPad and Office Text Converter Memory Corruption Vulnerability - CVE-2009-0087

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:

  • Do not open or save Microsoft Office files that you receive from untrusted sources or that you receive unexpectedly from trusted sources with affected versions of WordPad or Microsoft Office.

    Do not open Office, RTF or Write files from untrusted sources using any software listed as affected in this bulletin on systems that are not updated with the security updates that accompany this bulletin. This vulnerability could be exploited when a user opens a specially crafted file.

    This includes files that have .wri, .rtf, and .doc file associations. WordPad and Office could also be used to manually open documents. This includes all files that have .wri, .rtf, and .doc file extensions as well files with other extensions. Be aware that WordPad could also be used to open specially crafted documents regardless of the file name extension.

  • Disable the Word 6 converter by restricting access

    An administrator can apply an access control list to affected converters to ensure that the converter is no longer loaded by WordPad and Office. This effectively prevents exploitation of the issue using this attack vector.

    Warning Undo this workaround before installing this security update.

    In order to apply the access list, run the following commands from the command prompt. Note that some of these may result in an error message, this is expected.

    echo y| cacls "%ProgramFiles%\Windows NT\Accessories\mswrd6.wpc" /E /P everyone:N
    echo y| cacls "%ProgramFiles%\Common Files\Microsoft Shared\TextConv\mswrd632.wpc" /E /P everyone:N

    echo y| cacls "%ProgramFiles%\Common Files\Microsoft Shared\TextConv\mswrd632.cnv" /E /P everyone:N
    echo y| cacls "%ProgramFiles(x86)%\Common Files\Microsoft Shared\TextConv\mswrd632.wpc" /E /P everyone:N
    echo y| cacls "%ProgramFiles(x86)%\Common Files\Microsoft Shared\TextConv\mswrd632.cnv" /E /P everyone:N
    echo y| cacls "%ProgramFiles%\Windows NT\Accessories\mswrd664.wpc" /E /P everyone:N
    echo y| cacls "%ProgramFiles(x86)%\Windows NT\Accessories\mswrd6.wpc" /E /P everyone:N

    Impact of workaround. Upon implementing the workaround, the user will no longer be able to convert Word 6 documents to WordPad RTF or Word 2003 documents. Microsoft Office Word will return an error saying, "The file appears to be corrupted."

    How to undo the workaround.

    echo y| cacls "%ProgramFiles%\Windows NT\Accessories\mswrd6.wpc" /E /R everyone
    echo y| cacls "%ProgramFiles%\Common Files\Microsoft Shared\TextConv\mswrd632.wpc" /E /R everyone

These converters and filters allow Office to use additional document formats that were not natively supported. The Microsoft Office Converter Pack is available as a Web download.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. 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? 
In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially crafted WordPerfect 6.x 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 WordPerfect 6.x document 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 that takes them to the attacker's web site.

What systems are primarily at risk from the vulnerability? 
All systems where WordPad is used to open up Word documents from untrusted sources, such as workstations or terminal servers, are primarily at risk of this vulnerability. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this..

What does the update do? 
The update removes the vulnerability by modifying the way that Word validates the length of a string when parsing a WordPerfect document.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No, Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued.

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.

A remote code execution vulnerability exists in WordPad as a result of memory corruption when a user opens a specially crafted Word file.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2009-0235.

Mitigating Factors for WordPad Word 97 Text Converter Stack Overflow Vulnerability - CVE-2009-0235

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. After they click the link, they would be prompted to perform several actions. An attack could only occur after they performed these actions.
  • The vulnerability could not 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.
  • An attacker who successfully exploited this vulnerability could gain the same privileges as the user. Users whose accounts are configured to have fewer privileges on the system could be less impacted than users who operate with administrative privileges.
  • A website attempting to exploit the vulnerability would cause a dialog box to appear. The user would be prompted to decide if they wanted to open the file or not, unless the user had previously unchecked the option "Always ask before opening this type of file."

Workarounds for WordPad Word 97 Text Converter Stack Overflow Vulnerability - CVE-2009-0235

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:

  • Do not open or save Microsoft Office, RTF or Write 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. This includes all files that have .wri, .rtf, and .doc file extensions as well files with other extensions. Be aware that WordPad could also be used to open specially crafted documents regardless of the file name extension.
  • Disable the Word 6 converter by restricting access to mswrd8.wpc

    An administrator can apply an access control list to the affected converter to ensure it is no longer loaded by WordPad. This effectively prevents exploitation of the issue.

    Warning Undo this workaround before installing this security update.

    In order to apply the access list, run the following commands from the command prompt. Note that some of these may result in an error message, this is expected.

    echo y| cacls "%ProgramFiles%\Common Files\Microsoft Shared\TextConv\mswrd832.cnv" /E /P everyone:N
    echo y| cacls "%ProgramFiles(x86)%\Common Files\Microsoft Shared\TextConv\mswrd832.cnv" /E /P everyone:N
    echo y| cacls "%ProgramFiles%\Windows NT\Accessories\mswrd8.wpc" /E /P everyone:N
    echo y| cacls "%ProgramFiles%\Windows NT\Accessories\mswrd864.wpc" /E /P everyone:N
    echo y| cacls "%ProgramFiles(x86)%\Windows NT\Accessories\mswrd8.wpc" /E /P everyone:N

    Impact of workaround. Upon implementing the workaround, the user will no longer be able to convert Word 6 documents to WordPad RTF or Word 2003 documents. Microsoft Office Word will return an error saying, "The file appears to be corrupted."

    How to undo the workaround.

    echo y| cacls "%ProgramFiles%\Common Files\Microsoft Shared\TextConv\mswrd832.cnv" /E /R everyone
    echo y| cacls "%ProgramFiles(x86)%\Common Files\Microsoft Shared\TextConv\mswrd832.cnv" /E /R everyone
    echo y| cacls "%ProgramFiles%\Windows NT\Accessories\mswrd8.wpc" /E /R everyone
    echo y| cacls "%ProgramFiles%\Windows NT\Accessories\mswrd864.wpc" /E /R everyone
    echo y| cacls "%ProgramFiles(x86)%\Windows NT\Accessories\mswrd8.wpc" /E /R everyone

Deployment Information

Installing the Update

When you install this security update, the installer checks to see if one or more of the files that are being updated on your system have previously been updated by a Microsoft hotfix.

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.

/quietQuiet mode. This is the same as unattended mode, but no status or error messages are displayed.
Restart Options
/norestartDoes not restart when installation has completed.
/forcerestartRestarts 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.
/promptrestartDisplays a dialog box prompting the local user to allow a restart.
Special Options
/overwriteoemOverwrites OEM files without prompting.
/nobackupDoes not back up files needed for uninstall.
/forceappscloseForces other programs to close when the computer shuts down.

/integrate:pathIntegrates the update into the Windows source files. These files are located at the path that is specified in the switch.
/extract[:path]Extracts files without starting the Setup program.
/EREnables extended error reporting.
/verboseEnables verbose logging. During installation, creates %Windir%\CabBuild.log. This log details the files that are copied. Using this switch may cause the installation to proceed more slowly.

Note You can combine these switches into one command. For backward compatibility, the security update also supports many of 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 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.
