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 Windows version
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to see the installed Windows version
    Affected if The version is Windows 7 (any version), Windows 8.1 (any version), or Windows 10 (any version including 1511 and 1607)
  2. Check for affected Microsoft Office installations
    Open any Office application, go to File > Account > About [App] to see the version, or check Add/Remove Programs for Microsoft Office installations
    Affected if Office 2007 or Office 2010 is installed
  3. Check for affected Lync or Skype for Business installations
    Open Lync or Skype for Business, check Help > About, or look in Add/Remove Programs for Microsoft Lync 2010, Lync 2013, or Skype for Business 2016
    Affected if Lync 2010, Lync 2013, or Skype for Business 2016 is installed
  4. Check for Live Meeting 2007 or Word Viewer
    Look in Add/Remove Programs for Microsoft Office Live Meeting 2007 or Microsoft Word Viewer
    Affected if Either Microsoft Live Meeting 2007 or any version of Microsoft Word Viewer is installed
  5. Verify security update installation
    Run 'powershell Get-HotFix -Id KB3164033' or check Windows Update history for security update KB3164033 (part of MS16-074)
    Affected if The security update KB3164033 is NOT installed and the system matches any of the affected versions in steps 1-4

The system is affected if it runs any of the listed Windows or Office versions AND the MS16-074 security update (KB3164033) has not been applied.
