Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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 Chrome executable: on Windows look in Program Files/Google/Chrome/Application/, on macOS in /Applications/, or on Linux check common paths like /usr/bin/google-chrome
    Affected if Google Chrome is not installed on the system
  2. Obtain the installed Chrome version
    Open Chrome and navigate to chrome://version, or run 'google-chrome --version' from command line on Linux/Mac, or check the properties of chrome.exe on Windows
    Affected if Cannot determine the version - version information is not accessible
  3. Compare version against the affected range
    Extract the full version number (e.g., 66.0.3882.126) and compare numerically to 67.0.3396.62
    Affected if Installed version is less than 67.0.3396.62 (for example, 66.x.x.x or any earlier version)
  4. Confirm the vulnerability trigger condition
    This vulnerability requires viewing a specially crafted HTML page with malicious JavaScript - the flaw is in V8's handling of certain JavaScript operations, not in a configuration setting
    Affected if User visits a malicious webpage while running a vulnerable Chrome version

User is affected if Google Chrome is installed and the running version is earlier than 67.0.3396.62.
