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
Integer overflow in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, and SeaMonkey before 2.0.6, allows remote attackers to execute arbitrary code via plugin content with many parameter elements.

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 if Firefox is installed and retrieve its version
    On Windows: Check Help > About Firefox or run 'firefox --version' from command line. On Linux: Run 'firefox --version' or check /usr/lib/firefox. On macOS: Check About Firefox from application menu or run '/Applications/Firefox.app/Contents/MacOS/firefox --version'
    Affected if Version is 3.5.1 through 3.5.10, 3.6.1 through 3.6.3, or any version between 3.5.0 and 3.6.7 that is not 3.5.11 or higher, or 3.6.7 or higher
  2. Identify if SeaMonkey is installed and retrieve its version
    On Windows: Check Help > About SeaMonkey or run 'seamonkey --version' from command line. On Linux: Run 'seamonkey --version' or check /usr/lib/seamonkey. On macOS: Check About SeaMonkey from application menu
    Affected if Version is 1.0.x, 1.1.x, or any 2.0.x version up to and including 2.0.5
  3. Confirm the vulnerability applies only when plugins are enabled
    This vulnerability is triggered through plugin content with many parameter elements. Check if any plugins (such as Adobe Flash, Java, Silverlight) are installed and enabled in the browser. On Firefox: Go to Add-ons > Plugins. On SeaMonkey: Go to Tools > Add-ons > Plugins
    Affected if Any vulnerable version (as identified in steps 1-2) with plugins installed and enabled in the browser

A user is affected if they are running Firefox 3.5.1 through 3.5.10, Firefox 3.6.1 through 3.6.3, or SeaMonkey 1.0.x through 2.0.5, and have plugins enabled in the browser.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 2.0.5
Interim mitigation

Upgrade to Firefox 3.5.11+, 3.6.7+, or later versions, or SeaMonkey 2.0.6+ to remediate this vulnerability.

Recommended fix High confidence

Firefox 3.5.11 or later (3.6.7+), or migrate to current supported Firefox release; SeaMonkey 2.0.6 or later

  1. 1. Check current Firefox version by navigating to Help > About Firefox
  2. 2. If running Firefox 3.5.x or 3.6.x, download and install the latest supported Firefox release from www.mozilla.org
  3. 3. If running SeaMonkey 1.x or 2.0.x through 2.0.5, download and install SeaMonkey 2.0.6 or later from www.mozilla.org
  4. 4. After upgrade, verify the new version is installed by checking Help > About
Caveat Firefox 3.5/3.6 and SeaMonkey 1.x/2.0.x are obsolete and unsupported - upgrading to current Firefox may require migration of bookmarks and settings
