Check if Firefox, Thunderbird, or SeaMonkey is installed on the system. On Windows, look in Program Files for Mozilla Firefox, Mozilla Thunderbird, or SeaMonkey. On Linux, check /usr/lib/firefox, /usr/lib/thunderbird, or /usr/lib/seamonkey. On macOS, check /Applications for Firefox, Thunderbird, or SeaMonkey.

Affected if Any of these three products are installed
Check Firefox version

If Firefox is installed, open Firefox and go to Help > About Firefox, or run 'firefox --version' from command line. The version will be displayed as 2.0.0.x

Affected if Version is 2.0.0.12 or earlier (any version <= 2.0.0.12)
Check Thunderbird version

If Thunderbird is installed, open Thunderbird and go to Help > About Thunderbird, or run 'thunderbird --version' from command line. The version will be displayed as 2.0.0.x

Affected if Version is 2.0.0.12 or earlier (any version <= 2.0.0.12)
Check SeaMonkey version

If SeaMonkey is installed, open SeaMonkey and go to Help > About SeaMonkey, or run 'seamonkey --version' from command line. The version will be displayed as 1.1.x

Affected if Version is 1.1.8 or earlier (any version <= 1.1.8)

The system is affected if any of Firefox version 2.0.0.12 or earlier, Thunderbird version 2.0.0.12 or earlier, or SeaMonkey version 1.1.8 or earlier is installed and actively used for web browsing or email.

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.

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.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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.

Check your environment

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.
