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. Verify Microsoft Word is installed
    Check for the presence of WINWORD.EXE in typical installation paths such as C:\Program Files\Microsoft Office\Office (for Office 2000/2002/2003) or C:\Program Files (x86)\Microsoft Office\Office, or open Word and look for the application.
    Affected if Microsoft Word is not installed on the system.
  2. Determine installed Word version via About dialog
    Open Microsoft Word, click Help menu, then select About Microsoft Office Word. Note the version number displayed (e.g., Word 2000 shows 9.0, Word 2002 shows 10.0, Word 2003 shows 11.0).
    Affected if The version displayed is 9.0 (Word 2000), 10.0 (Word 2002), or 11.0 (Word 2003).
  3. Determine installed Word version via registry
    Open Registry Editor (regedit.exe), navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\{version}\Word\InstallRoot (where {version} is 9.0, 10.0, or 11.0), and check the value to confirm the installation path.
    Affected if The registry contains version keys 9.0, 10.0, or 11.0 under the Office key, confirming Word 2000, 2002, or 2003 respectively.
  4. Check file version of WINWORD.EXE
    Locate WINWORD.EXE in the installation directory, right-click the file, select Properties, go to the Details tab, and note the File Version field.
    Affected if The file version corresponds to Word 2000 (version 9.0.x), Word 2002 (version 10.0.x), or Word 2003 (version 11.0.x).

The system is affected if Microsoft Word version 9.0 (2000), 10.0 (2002), or 11.0 (2003) is installed, as these specific versions contain the buffer overflow vulnerability.
