Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Microsoft Works 6 File Converter, as used in Office 2003 SP2 and SP3, Works 8.0, and Works Suite 2005, allows remote attackers to execute arbitrary code via a .wps file with crafted section header index table information, aka "Microsoft Works File Converter Index Table Vulnerability."

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A buffer overflow vulnerability in Microsoft Works 6 File Converter allows remote code execution when parsing specially crafted .wps files. The vulnerability stems from improper validation of section header index table information in the file parser, which can be exploited to overwrite memory and execute arbitrary code.

MitigationApply the Microsoft security update (MS08-011) to patch the Works File Converter, and avoid opening untrusted .wps files from unknown sources until patches are deployed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check for Microsoft Works installation
    Open Control Panel > Programs and Features, look for Microsoft Works 8.0 or Microsoft Works 2005 in the installed programs list
    Affected if Microsoft Works 8.0 or Microsoft Works 2005 is listed as installed
  2. Check for Microsoft Office 2003 installation
    Open Control Panel > Programs and Features, look for Microsoft Office 2003 in the installed programs list
    Affected if Microsoft Office 2003 is installed (it included the Works File Converter component)
  3. Locate the Works File Converter component
    Search for files named wkcvx1.dll or wksconverter.exe in the Microsoft Office or Windows system directories
    Affected if The Works File Converter DLL or executable is present on the system
  4. Verify converter version
    Right-click the converter DLL file, select Properties, and check the File Version field against affected version ranges
    Affected if The converter version matches the unpatched version from 2003-2008 era

The system is affected if Microsoft Works 8.0, Works 2005, or Office 2003 is installed AND the Works File Converter component is present, and the converter has not been patched via MS08-011.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the Microsoft security update (MS08-011) to patch the Works File Converter, and avoid opening untrusted .wps files from unknown sources until patches are deployed.

Recommended fix High confidence

Migrate from Office 2003/Works Suite 2005 to Microsoft 365, Office 2019, or Office 2021

  1. Apply Microsoft Security Bulletin MS08-011 patch (KB955428) which addresses this vulnerability in Microsoft Works File Converter
  2. If MS08-011 is no longer available from Microsoft Update, the affected products (Office 2003 SP2/SP3, Works 8.0, Works Suite 2005) have reached end of support
  3. Migrate to a currently supported Microsoft Office version (such as Microsoft 365, Office 2019, or Office 2021) to receive ongoing security updates
  4. Ensure Microsoft Defender or an up-to-date antivirus solution is running to provide behavioral detection for suspicious .wps file handling
  5. Implement network-level filtering to block .wps file attachments from untrusted sources via email or web downloads
Caveat Migrating from Office 2003 to modern Office versions may require workflow adjustments, and legacy .wps files from Works 6 may need conversion; ensure compatibility checking before full deployment
