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. Verify Google Chrome is installed
    Check for Google Chrome installation on the system. On Windows, look for Chrome in Program Files or the registry. On macOS, check /Applications/Google Chrome. On Linux, check for chrome or google-chrome packages.
    Affected if Google Chrome is present on the system
  2. Obtain the installed Chrome version
    Open Google Chrome, click the three-dot menu, select Help, then About Google Chrome. The version number will be displayed on that page.
    Affected if Unable to determine version (Chrome not accessible or not installed)
  3. Compare version against the affected range
    Note the version number displayed in the About page and compare it to 77.0.3865.75. Any version prior to 77.0.3865.75 (such as 76.x.x.x or earlier) falls within the affected range.
    Affected if The installed version is less than 77.0.3865.75 (for example, 76.0.3809.100)

A user is affected if Google Chrome is installed and the installed version is below 77.0.3865.75, making the download manager vulnerable to domain spoofing.
