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 unspecified vulnerabilities in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via unknown vectors related to the layout engine.

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

Multiple critical vulnerabilities in the Mozilla layout engine affecting Firefox before 2.0.0.15, Thunderbird before 2.0.0.14, and SeaMonkey before 1.1.10 allow remote attackers to potentially execute arbitrary code or cause application crashes via unspecified vectors.

MitigationUpdate affected Mozilla products to the patched versions (Firefox 2.0.0.15+, Thunderbird 2.0.0.14+, SeaMonkey 1.1.10+) or migrate to current supported versions of these applications.

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 installed Mozilla product
    Check for presence of Firefox, Thunderbird, or SeaMonkey in your system. On Windows, look in Program Files for Mozilla Firefox, Mozilla Thunderbird, or SeaMonkey folders. On Linux, check /usr/bin for firefox, thunderbird, or seamonkey commands. On macOS, check /Applications for these applications.
    Affected if Any of Firefox, Thunderbird, or SeaMonkey is installed
  2. Determine Firefox version
    For Firefox: Open browser, go to Help > About Firefox, or enter 'about:Firefox' in the address bar, or run 'firefox --version' from command line.
    Affected if Version is 2.0, or 2.0.0.1 through 2.0.0.14, or any version <= 2.0.0.14
  3. Determine Thunderbird version
    For Thunderbird: Open application, go to Help > About Thunderbird, or run 'thunderbird --version' from command line.
    Affected if Version is 2.0.0.0 through 2.0.0.14, or any version <= 2.0.0.14 (excluding 2.0.0.13 and 2.0.0.14 based on the list)
  4. Determine SeaMonkey version
    For SeaMonkey: Open application, go to Help > About SeaMonkey, or run 'seamonkey --version' from command line.
    Affected if Version is 1.1, 1.1.2 through 1.1.9, or any version <= 1.1.9

If any of these Mozilla products are installed and the detected version matches the affected ranges listed (Firefox <= 2.0.0.14, Thunderbird <= 2.0.0.14, SeaMonkey <= 1.1.9), the environment is vulnerable to CVE-2008-2798.

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 2.0.0.14
Interim mitigation

Update affected Mozilla products to the patched versions (Firefox 2.0.0.15+, Thunderbird 2.0.0.14+, SeaMonkey 1.1.10+) or migrate to current supported versions of these applications.

Recommended fix High confidence

Firefox 2.0.0.15+ | Thunderbird 2.0.0.15+ | SeaMonkey 1.1.10+

  1. Identify the installed Mozilla product (Firefox, Thunderbird, or SeaMonkey) and current version
  2. Backup any necessary data and bookmarks
  3. Uninstall the current vulnerable version
  4. Download the fixed version: Firefox 2.0.0.15 or later, Thunderbird 2.0.0.15 or later, or SeaMonkey 1.1.10 or later
  5. Install the fixed version
  6. Restart the application and verify it runs without errors
Caveat These are very old versions of Mozilla products; upgrading may require migration to a modern browser/email client as these legacy versions are no longer supported
