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
Double free vulnerability in Microsoft Word 2002 SP3 allows remote attackers to execute arbitrary code via a Word document with crafted List Format Override (LFO) records, aka "Word Pointer 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 · high confidence

A double-free vulnerability exists in Microsoft Word 2002 SP3 when parsing specially crafted Word documents containing malicious List Format Override (LFO) records. This memory corruption allows remote attackers to execute arbitrary code by tricking users into opening a malformed document.

MitigationApply the Microsoft security update (MS10-056) to patch the vulnerability, or upgrade to a supported Microsoft Office version. Until patched, disable Word's file opening in untrusted environments and warn users not to open documents from untrusted sources.

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 installed Microsoft Word version
    Open Word, go to Help > About Microsoft Office Word, or check registry key HKEY_CLASSES_ROOT\Word.Application\CurVer, or run 'wmic product where "name like '%Office%Word%'" get name,version'
    Affected if The version displayed is Microsoft Word 2002 (version 10.x)
  2. Confirm service pack level
    In Word, check Help > About, or check registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\10.0\Word\InstallRoot for SP3 indicator, or inspect the version string for '10.0.xxxx' where xxxx indicates SP3
    Affected if Word 2002 is at Service Pack 3 (SP3) level
  3. Verify .doc file association with Word
    Check file associations via Control Panel > Default Programs > Associate a file type or protocol with a program, looking for .doc extensions pointing to WINWORD.EXE from Office 10
    Affected if .doc files open with Microsoft Word 2002 as the default handler
  4. Inspect for recent Word document processing
    Review recent file access events in Windows Event Viewer under Security or Application logs, or check recent documents in Word's Recent Files list
    Affected if Users have recently opened .doc files from potentially untrusted sources

Environment is affected if Microsoft Word 2002 SP3 is installed and users open .doc files, as the double-free vulnerability triggers when parsing malicious LFO records in crafted documents.
