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 Word 2003 SP3 allows remote attackers to execute arbitrary code via a crafted document, aka "Microsoft Word Stack Overflow 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 stack-based buffer overflow vulnerability exists in Microsoft Word 2003 SP3 that allows remote attackers to execute arbitrary code through a specially crafted document file. The vulnerability exploits how Word handles malformed data in documents, overflowing a stack buffer and allowing code execution in the context of the current user.

MitigationSince Microsoft Word 2003 is end-of-life with no official security updates, organizations should migrate to supported Office versions or implement compensating controls such as restricting document opening from untrusted sources and deploying the Microsoft Office Isolated Conversion Environment (MOICE).

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. Identify Microsoft Word installation
    Check Add/Remove Programs in Control Panel, or look for Microsoft Office 2003 entries. The typical install path is C:\Program Files\Microsoft Office\OFFICE11\
    Affected if Microsoft Word 2003 is listed as installed software
  2. Confirm the exact Word version
    Launch Word and navigate to Help > About Microsoft Office Word, or right-click WINWORD.EXE and select Properties > Details to view the version number
    Affected if The installed version is Microsoft Word 2003 (any build)
  3. Determine if documents can be opened
    This vulnerability is triggered when Word opens a specially crafted .doc file. By default, Word 2003 allows opening documents from any location
    Affected if Word can open document files (this is the default state)

If Microsoft Word 2003 is installed and document opening is enabled, the environment is affected by this vulnerability

Mitigation

Since Microsoft Word 2003 is end-of-life with no official security updates, organizations should migrate to supported Office versions or implement compensating controls such as restricting document opening from untrusted sources and deploying the Microsoft Office Isolated Conversion Environment (MOICE).

Recommended fix High confidence

Microsoft 365, Office 2021, or Office 2019

  1. 1. Backup all important Microsoft Word documents and any custom templates or add-ins.
  2. 2. Uninstall Microsoft Office 2003 (including Word 2003) from the system.
  3. 3. Install a supported version of Microsoft Office (such as Microsoft 365, Office 2021, or Office 2019) which includes Word.
  4. 4. After installation, open Microsoft Word and verify all documents, macros, and customizations function correctly.
  5. 5. Ensure Windows Update is enabled and configure automatic updates for Office to receive future security patches.
Caveat Upgrading from Office 2003 may require purchase of a newer Office license; some legacy file formats, macros, and third-party add-ins may require migration or replacement; the user interface has changed significantly in newer versions
