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

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

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

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