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 12.0.742.112 does not properly handle Cascading Style Sheets (CSS) token sequences, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown 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. Determine installed Chrome version
    Open Google Chrome, click the wrench icon (top right), select 'About Google Chrome' or navigate to chrome://version to view the full version string
    Affected if The displayed version number is less than 12.0.742.112 (for example, 12.0.742.100, 11.x, or earlier)
  2. Verify Chrome is the primary browser
    Confirm that the Chrome installation being checked is the production browser used, not a parallel installation or older channel build
    Affected if The affected Chrome version is actively used for browsing web content

You are affected if the installed Google Chrome version is below 12.0.742.112, as the memory corruption vulnerability in CSS token parsing can be triggered by visiting malicious web pages.
