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 11.0.696.57 does not properly handle PDF documents with multipart encoding, which allows remote attackers to cause a denial of service (out-of-bounds read) 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

Google Chrome before 11.0.696.57 contains an out-of-bounds read vulnerability in its PDF parsing logic when handling PDF documents with multipart encoding, allowing remote attackers to cause denial of service via crafted documents.

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 Chrome and navigate to chrome://chrome, or run 'chrome --version' from command line
    Affected if Version shown is earlier than 11.0.696.57
  2. Confirm PDF functionality is accessible
    Attempt to open a PDF file in Chrome or navigate to chrome://plugins to verify the PDF viewer is present
    Affected if PDF viewer plugin is enabled and functional (this is the default state)
  3. Verify the vulnerability context applies
    Determine if the system handles or displays untrusted PDF documents, as the flaw triggers when processing PDFs with multipart encoding
    Affected if Users open or preview PDF files from external or untrusted sources within Chrome

You are affected if your Chrome version is below 11.0.696.57 and you use the built-in PDF viewer to open documents.
