Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Google Chrome before 17.0.963.46 does not properly check signatures, which allows remote attackers to cause a denial of service (application crash) via unspecified vectors.

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. Check installed Google Chrome version
    Navigate to Chrome menu > Help > About Google Chrome, or visit chrome://settings/help, or run 'google-chrome --version' in terminal
    Affected if Version displayed is less than 17.0.963.46
  2. Verify version number format
    Note the full version string (e.g., 17.0.963.45) - ensure it includes all four version components
    Affected if Any version below 17.0.963.46 (e.g., 17.0.963.45, 16.x.x.x, 15.x.x.x)
  3. Confirm Chrome is the affected product
    Ensure the browser being checked is Google Chrome (not Chromium, Edge, or other Chromium-based browsers)
    Affected if The browser is Google Chrome and version is below 17.0.963.46

If the installed Google Chrome version is less than 17.0.963.46, the environment is affected by this signature verification vulnerability.
