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
Stack-based buffer overflow in Microsoft Office Excel 2002 SP3 allows remote attackers to execute arbitrary code via an Excel file with a malformed RTD (0x813) record, aka "Excel RTD Memory Corruption 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.

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. Confirm Excel 2002 is installed
    Open Excel, go to Help > About Microsoft Excel, or check Programs and Features for Microsoft Office Excel 2002
    Affected if Excel 2002 is listed as installed on the system
  2. Verify the exact Excel version and Service Pack
    Check the exact version by opening Excel, clicking Help > About, or running: excel.exe /? from command line, or checking registry key HKEY_CLASSES_ROOT\Excel.Application\CurVer
    Affected if The version shows Microsoft Excel 2002 without Service Pack 3 or an earlier version
  3. Check if the system receives regular Office security updates
    Run Windows Update or check the installed updates for any Microsoft security patches related to Excel
    Affected if No recent Office security updates are installed or the system is not configured for automatic updates
  4. Determine user behavior regarding opening Excel files
    Review how users typically handle Excel attachments or files from external sources
    Affected if Users routinely open Excel files from untrusted or unknown sources without prior scanning

The environment is affected if Excel 2002 SP3 or earlier is installed and users open Excel files from untrusted sources, as the vulnerability is triggered by parsing a malformed RTD (0x813) record in a maliciously crafted Excel file.

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

Apply Microsoft security patches for Office Excel 2002 SP3 and avoid opening untrusted Excel files from unknown sources to prevent exploitation.

Recommended fix Moderate confidence

Microsoft 365, Office 2019, or Office 2016 (all contain the security fix and are currently supported)

  1. 1. Microsoft Office Excel 2002 is no longer supported by Microsoft and no longer receives security updates.
  2. 2. Upgrade to a currently supported Microsoft Office version (such as Microsoft 365, Office 2019, or Office 2016) which includes the security fix for this vulnerability.
  3. 3. Verify that all Microsoft Office applications are updated to the latest version after migration.
  4. 4. Ensure antivirus/anti-malware solutions are active and up-to-date as an additional layer of protection.
  5. 5. Implement application whitelisting to prevent execution of unauthorized code or macros.
Caveat Upgrading from Office 2002 may require license purchase, and some legacy features or file formats may behave differently in newer versions; macro settings may need reconfiguration
