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. Determine installed Chrome version
    Run 'google-chrome --version' in terminal, or on Linux systems check the package manager: 'rpm -q google-chrome' or 'dpkg -l | grep google-chrome'
    Affected if The command fails (Chrome not installed) or returns a version lower than 73.0.3683.75
  2. Verify Chrome browser presence on OpenSUSE systems
    On OpenSUSE Leap or Backports, run 'rpm -qa | grep -i chrome' or check Yast Software Management for installed Chrome packages
    Affected if Google Chrome is installed on OpenSUSE Leap 15.0, 15.1, 42.3, or from sle-15 backports repo regardless of version
  3. Confirm browser is actual Chrome (not Chromium)
    Navigate to chrome://version in the browser address bar and check the 'Browser' and 'Profile Path' lines, or run 'google-chrome --product-version'
    Affected if The browser reports itself as Google Chrome with version < 73.0.3683.75, as Chromium may have different patch timelines

A system is affected if Google Chrome (not Chromium) is installed with version less than 73.0.3683.75, or any Google Chrome package from the listed OpenSUSE versions/repos is present.
