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
Use-after-free vulnerability in Microsoft Office 2007 SP3; 2010 SP2; 2013 Gold, SP1, and SP2; and 2013 RT Gold and SP1 allows remote attackers to execute arbitrary code via a crafted Office document, aka "Microsoft Office Component Use After Free 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

Use-after-free vulnerability in Microsoft Office components allows remote attackers to execute arbitrary code via crafted malicious Office documents. The vulnerability stems from improper memory management where memory is accessed after being freed, leading to potential code execution.

MitigationApply Microsoft security updates for the affected Office versions (2007 SP3, 2010 SP2, 2013 Gold/SP1/SP2, 2013 RT Gold/SP1). Implement email/attachment filtering and consider disabling OLE embedding and ActiveX controls in Office 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. Verify Office installation and version
    Open a command prompt and run: 'reg query "HKLM\Software\Microsoft\Office\ClickToRun\Configuration" /v VersionToReport' for Office 365/Click-to-Run, or check Program Files for Microsoft Office folders (Office12 for 2007, Office14 for 2010, Office15 for 2013). Alternatively, open any Office application, go to File > Account > About [App] to see the full version number.
    Affected if The installed version is Microsoft Office 2007, 2010, or 2013 (any sub-version within these product lines).
  2. Identify exact Office product version
    Open Word/Excel/PowerPoint, click File > Account > About [Product]. Note the full version number shown (e.g., 15.0.4569.1504 for Office 2013). Compare against Microsoft's official version listings for this CVE.
    Affected if The version matches Office 2007, 2010, or 2013 and has not had the specific security update for CVE-2014-6364 applied.
  3. Check for security update installation
    Open Windows Update, view update history, or run: 'reg query "HKLM\Software\Microsoft\Updates" /s' to search for update packages containing references to CVE-2014-6364 or MS14-082 (the security bulletin for this CVE).
    Affected if The security update MS14-082 is NOT installed for the detected Office version.
  4. Assess document handling exposure
    Review whether users regularly open Office documents from external sources, untrusted emails, or downloads. Check if Preview Pane is enabled in Outlook, as this can trigger parsing of malicious content.
    Affected if Users routinely open Office attachments from external or untrusted sources without additional sandboxing or scanning.

Your environment is affected if you have Microsoft Office 2007, 2010, or 2013 installed and the MS14-082 security update has not been applied, especially if users open Office documents from external sources.
