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 Google Chrome version on Windows or macOS
    Open Chrome and navigate to chrome://version, or run 'chrome --version' from command line
    Affected if The displayed version is earlier than 63.0.3239.108
  2. Check installed Chrome package version on Debian/Ubuntu
    Run 'dpkg -l | grep chrome' or 'apt-cache policy google-chrome-stable' in terminal
    Affected if The installed version is earlier than 63.0.3239.108-1
  3. Check installed Chrome package version on RHEL/CentOS
    Run 'rpm -qa | grep chrome' or 'yum info google-chrome-stable' in terminal
    Affected if The installed version is earlier than 63.0.3239.108-1
  4. Verify WebAssembly support is enabled
    In Chrome, navigate to chrome://flags/#enable-webassembly and confirm the flag is not set to Disabled
    Affected if WebAssembly is enabled (default state) AND the Chrome version is below 63.0.3239.108

A user is affected if their installed Google Chrome version is below 63.0.3239.108 and WebAssembly is enabled (the default state in vulnerable versions).
