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 the installed browser
    Check whether Microsoft Internet Explorer or Microsoft Edge is in use on the system. Open the browser and navigate to 'Help' > 'About Internet Explorer' or check the Microsoft Edge 'Settings' > 'About' section to confirm the browser name.
    Affected if The system uses Microsoft Edge (any version) or Microsoft Internet Explorer versions 7, 8, 9, 10, or 11.
  2. Check Internet Explorer version
    Open Internet Explorer, click 'Help' in the menu bar, and select 'About Internet Explorer'. Record the version number displayed.
    Affected if The version listed is 7, 8, 9, 10, or 11.
  3. Verify security update MS15-106 installation
    Open Windows Control Panel, navigate to 'Programs and Features', then click 'View installed updates' in the left panel. Search for security update KB3096443 (the update for MS15-106) in the list of installed updates.
    Affected if Security update KB3096443 or a subsequent Internet Explorer cumulative security update is NOT installed.
  4. Confirm Windows update status
    Open Windows Settings, go to 'Update & Security' > 'Windows Update', and click 'Check for updates'. Review the update history to verify if cumulative security updates released after October 2015 have been applied.
    Affected if No security updates for Internet Explorer or Edge have been installed since October 2015.

The system is affected if it runs Microsoft Internet Explorer versions 7-11 or Microsoft Edge of any version AND lacks security update MS15-106 (KB3096443) or subsequent cumulative updates.
