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 if PowerPoint 2010 is installed
    Open PowerPoint, go to File > Account > About PowerPoint to view the exact version number, or check Programs and Features for Microsoft Office Professional Plus 2010
    Affected if PowerPoint version is 2010 (14.x) and the system is missing KB3191855 or subsequent security updates
  2. Verify PowerPoint Viewer installation
    Check for installation of Microsoft PowerPoint Viewer in Programs and Features, or search for file PPTVIEW.EXE in Program Files
    Affected if PowerPoint Viewer is installed on the system (any version)
  3. Confirm Office Web Apps 2010 presence
    Check server inventory or documentation for deployment of Office Web Apps 2010, or query SharePoint Central Administration for Office Web Apps version
    Affected if Office Web Apps 2010 is deployed in the environment

A system is affected if it runs PowerPoint 2010 without KB3191855, any version of PowerPoint Viewer, or Office Web Apps 2010 without corresponding security patches.
