A remote code execution vulnerability exists in Microsoft Office Excel that could allow remote code execution if a user opens a specially crafted Excel file that includes a malformed record object. 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-2009-0549.

Mitigating Factors for Record Pointer Corruption Vulnerability - CVE-2009-0549

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.
  • 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 Record Pointer Corruption Vulnerability - CVE-2009-0549

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 untrusted sources

    The Microsoft Office Isolated Conversion Environment (MOICE) will protect Office 2003 installations by more securely opening Word, Excel, and PowerPoint binary format files.

    To install MOICE, you must have Office 2003 or 2007 Office system 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 handler for the .xls, .xlt, and .xla file formats. The following table describes the command to enable or to disable MOICE for the .xls, .xlt, and .xla file formats:

Command to enable MOICE to be the registered handlerCommand to disable MOICE as the registered handler
ASSOC .XLS=oice.excel.sheetASSOC .xls=Excel.Sheet.8
ASSOC .XLT=oice.excel.templateASSOC .xlt=Excel.Template
ASSOC .XLA=oice.excel.addinASSOC .xla=Excel.Addin

Note On Windows Vista and Windows Server 2008, the commands above will need to be run from an elevated command prompt.

For more information on MOICE, see 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 block 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\Excel\Security\FileOpenBlock]
      "BinaryFiles"=dword:00000001

      Note In order to use 'FileOpenBlock' with Office 2003, all of the latest Office 2003 security updates 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.

    How to undo the workaround:

    • For Office 2003

      Windows Registry Editor Version 5.00
      [HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\FileOpenBlock]
      "BinaryFiles"=dword:00000000
  • Do not open or save Excel 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 Record Pointer Corruption Vulnerability - CVE-2009-0549

Workarounds for Field Sanitization Memory Corruption Vulnerability - CVE-2009-0560

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 untrusted sources

    The Microsoft Office Isolated Conversion Environment (MOICE) will protect Office 2003 installations by more securely opening Word, Excel, and PowerPoint binary format files.

    To install MOICE, you must have Office 2003 or 2007 Office system 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 handler for the .xls, .xlt, and .xla file formats. The following table describes the command to enable or to disable MOICE for the .xls, .xlt, and .xla file formats:

Command to enable MOICE to be the registered handlerCommand to disable MOICE as the registered handler
ASSOC .XLS=oice.excel.sheetASSOC .xls=Excel.Sheet.8
ASSOC .XLT=oice.excel.templateASSOC .xlt=Excel.Template
ASSOC .XLA=oice.excel.addinASSOC .xla=Excel.Addin

Note On Windows Vista and Windows Server 2008, the commands above will need to be run from an elevated command prompt.

For more information on MOICE, see 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 block 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.

Note for Microsoft Office SharePoint Server 2007 The detection table described above is based on single-server Microsoft Office SharePoint Server 2007 deployments. The detection tools do not detect the applicability of the update on systems configured as part of a multiple-system SharePoint server farms. For more information about deploying updates on both stand-alone and multi server configurations, see Deploy software updates for Office SharePoint Server 2007.

Note If you have used an Administrative Installation Point (AIP) for deploying Office 2000, Office XP or Office 2003, you may not be able to deploy the update using SMS if you have updated the AIP from the original baseline. For more information, see the Office Administrative Installation Point heading in this section.

Office Administrative Installation Point

If you installed your application from a server location, the server administrator must update the server location with the administrative update and deploy that update to your system.

Update Compatibility Evaluator and Application Compatibility Toolkit

Updates often write to the same files and registry settings required for your applications to run. This can trigger incompatibilities and increase the time it takes to deploy security updates. You can streamline testing and validating Windows updates against installed applications with the Update Compatibility Evaluator components included with Application Compatibility Toolkit 5.0.

The Application Compatibility Toolkit (ACT) contains the necessary tools and documentation to evaluate and mitigate application compatibility issues before deploying Microsoft Windows Vista, a Windows Update, a Microsoft Security Update, or a new version of Windows Internet Explorer in your environment.
