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
    Open any Office application (Word, Excel, PowerPoint), go to File > Account > About [App] or check Add/Remove Programs for Microsoft Office installation
    Affected if The version shown is Office 2007 Service Pack 3 or Office 2010 Service Pack 2
  2. Confirm Office service pack level
    Run 'winver' or check Windows Update history for installed updates. Look for updates labeled 'Service Pack 3' for Office 2007 or 'Service Pack 2' for Office 2010
    Affected if Office 2007 with SP3 or Office 2010 with SP2 is installed (no further service packs applied)
  3. Check SharePoint Server 2010 installation
    Open SharePoint Central Administration, go to Upgrade and Migration > Check product and patch installation status. Look for Microsoft SharePoint Server 2010 entry
    Affected if SharePoint Server 2010 with Service Pack 2 is installed and not patched beyond the CVE fix
  4. Check Office Web Apps 2010 installation
    On SharePoint server, open SharePoint Management Shell and run Get-SPWebApplication to list web applications, then check if Office Web Apps 2010 is configured via Get-OfficeWebAppsFarm
    Affected if Office Web Apps 2010 SP2 is deployed in the environment
  5. Verify if CVE patch is installed
    Check Windows Update history or open Control Panel > Programs > View installed updates. Search for security update KB3115109 (for Office 2007) or KB3115121 (for Office 2010)
    Affected if The specific KB update for CVE-2016-0140 is NOT listed as installed

Your environment is affected if you have Office 2007 SP3, Office 2010 SP2, SharePoint Server 2010 SP2, or Office Web Apps 2010 SP2 installed and the corresponding security update (KB3115109 or KB3115121) has not been applied.
