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
Multiple integer overflows in the PDF functionality in Google Chrome before 20.0.1132.43 allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted document.

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.

dbcve analysis · high confidence

Integer overflow vulnerabilities in Google Chrome's PDF parsing functionality before version 20.0.1132.43 allow remote attackers to trigger heap corruption via crafted PDF documents, potentially causing denial of service (browser crash) or potentially enabling arbitrary code execution.

MitigationUpdate Google Chrome to version 20.0.1132.43 or later. Ensure auto-updates are enabled or deploy the update through enterprise patch management.

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 Chrome version number
    Open Chrome, click the menu icon (three dots), select Help, then About Google Chrome. The version number is displayed on that page. Alternatively, navigate to chrome://version/ in the address bar.
    Affected if The installed version is 20.0.1132.42 or earlier, or matches any of the specific affected versions (20.0.1132.0 through 20.0.1132.10).
  2. Verify PDF plugin or PDF viewer is enabled
    Navigate to chrome://settings/handlers in the address bar, or go to Settings > Privacy and security > Site Settings > Additional content settings > PDF documents. Check if the built-in PDF viewer is enabled.
    Affected if The PDF viewer is enabled (this is the component with the vulnerability).
