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 installed Chrome version
    Navigate to chrome://settings/help or run 'google-chrome --version' in terminal
    Affected if Version is lower than 64.0.3282.119
  2. Verify WebGL is enabled
    Visit chrome://gpu/ and look for WebGL under 'Graphics Feature Status', or inspect Chrome policy settings for Software Rendering List
    Affected if WebGL is enabled and Chrome version is below 64.0.3282.119
  3. Check Chrome package on Debian
    Run 'dpkg -l | grep google-chrome' or 'apt policy google-chrome-stable'
    Affected if Package version is below 64.0.3282.119 on Debian 8 or 9
  4. Check Chrome on RHEL
    Run 'rpm -q google-chrome-stable' or check installed package version
    Affected if Package version is below 64.0.3282.119 on RHEL 6

You are affected if Chrome version is below 64.0.3282.119 AND WebGL is enabled in the browser.
