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
Buffer overflow in the nsFloatManager::GetFlowArea function in Mozilla Firefox before 24.0, Firefox ESR 17.x before 17.0.9, Thunderbird before 24.0, Thunderbird ESR 17.x before 17.0.9, and SeaMonkey before 2.21 allows remote attackers to execute arbitrary code via crafted use of lists and floats within a multi-column layout.

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. Identify the Mozilla product installed
    Check which Mozilla application is installed: Firefox, SeaMonkey, or Thunderbird. On Windows check Programs and Features or the application executable properties. On Linux check the package manager or look for application binaries in /usr/bin or /opt.
    Affected if Any of Firefox, SeaMonkey, or Thunderbird is installed
  2. Determine the installed Firefox version
    For Firefox: Click menu > Help > About Firefox, or run 'firefox --version' from command line, or check the version in the executable properties.
    Affected if Version is 23.0.1 or lower, or any of 17.0 through 17.0.2, 19.0 through 20.0.1, 21.0, 22.0, or 23.0
  3. Determine the installed SeaMonkey version
    For SeaMonkey: Click menu > Help > About SeaMonkey, or run 'seamonkey --version' from command line.
    Affected if Version is 2.20 or lower, or any of 2.0 through 2.0.10
  4. Determine the installed Thunderbird version
    For Thunderbird: Click menu > Help > About Thunderbird, or run 'thunderbird --version' from command line. Identify if it is ESR or standard version.
    Affected if Standard version is 17.0.9 or lower, or any of 17.0 through 17.0.8. ESR version is any of 17.0 through 17.0.8.
  5. Check for multi-column layout usage
    Inspect web content or email content being rendered. Look for CSS 'column-count', 'column-width', or 'columns' properties in any HTML/CSS being processed, or check if the browser is visiting pages that use multi-column layouts.
    Affected if Multi-column CSS layouts are being rendered - this is the feature that must be enabled for the vulnerability to be triggerable

The user is affected if they have Firefox 23.0.1 or lower, SeaMonkey 2.20 or lower, or Thunderbird 17.0.9 or lower (or Thunderbird ESR 17.0.8 or lower) AND are processing multi-column layout content.
