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
Microsoft Office 2007 SP3, Office 2010 SP2, Office 2013 SP1, Office for Mac 2011, and Office 2016 for Mac allow remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via a crafted document, aka "Microsoft Office Information Disclosure 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. Check installed Microsoft Office version on Windows
    Open Word/Excel/PowerPoint, go to File > Account > About [App] to see the version number, or check registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration or the Office install directory for version info
    Affected if Version is 2007, 2010, or 2013 (any sub-version)
  2. Check installed Microsoft Office for Mac version
    Open any Office app, go to [App] > About [App], or navigate to /Applications and right-click > Get Info on the Office app to view the version number
    Affected if Version is 2011 or 2016 (any sub-version)
  3. Verify if security update KB3204062 is applied
    Open Windows Update > View update history, or check Control Panel > Programs and Features > Installed Updates for KB3204062
    Affected if KB3204062 is NOT installed and Office version matches 2007, 2010, or 2013

You are affected if you have Microsoft Office 2007, 2010, 2013 (Windows) or Office 2011/2016 (Mac) and the corresponding security update KB3204062 has not been installed.
