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 the nsGenericDOMDataNode::SetTextInternal function in Mozilla Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, Thunderbird before 3.0.5, and SeaMonkey before 2.0.5 allows remote attackers to execute arbitrary code via a DOM node with a long text value that triggers a heap-based buffer overflow.

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

Integer overflow in nsGenericDOMDataNode::SetTextInternal allows remote attackers to cause a heap-based buffer overflow via a DOM node containing an excessively long text value, enabling arbitrary code execution.

MitigationUpgrade to Firefox 3.5.10+/3.6.4+, Thunderbird 3.0.5+, or SeaMonkey 2.0.5+; consider disabling JavaScript or restricting untrusted content until patches are deployed.

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. Check Firefox version
    Run 'firefox --version' or look in Help > About Firefox
    Affected if Version is 3.5.0 through 3.5.9, 3.6.0 through 3.6.3, or any 3.5.x build listed in the affected versions
  2. Check SeaMonkey version
    Run 'seamonkey --version' or look in Help > About SeaMonkey
    Affected if Version is 1.0.x through 1.1, or 2.0.4 or earlier
  3. Check Thunderbird version
    Run 'thunderbird --version' or look in Help > About Thunderbird
    Affected if Version is 3.0.4 or earlier, or 0.1 through 1.0.2 inclusive

You are affected if any installed Mozilla product (Firefox, SeaMonkey, Thunderbird) matches one of the specific version numbers or ranges listed in the affected products list.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

Upgrade available Upgrade to a release after 3.0.4
Interim mitigation

Upgrade to Firefox 3.5.10+/3.6.4+, Thunderbird 3.0.5+, or SeaMonkey 2.0.5+; consider disabling JavaScript or restricting untrusted content until patches are deployed.

Recommended fix High confidence

Firefox 3.5.10+/3.6.4+, Thunderbird 3.0.5+, or SeaMonkey 2.0.5+ depending on product

  1. 1. Identify the exact Mozilla product and version currently installed (Firefox, Thunderbird, or SeaMonkey)
  2. 2. For Firefox 3.5.x users: Upgrade to Firefox 3.5.10 or later, or migrate to Firefox 3.6.4 or later
  3. 3. For Firefox 3.6.x users: Upgrade to Firefox 3.6.4 or later
  4. 4. For Thunderbird users: Upgrade to Thunderbird 3.0.5 or later
  5. 5. For SeaMonkey users: Upgrade to SeaMonkey 2.0.5 or later
  6. 6. After upgrade, verify the installed version matches the fixed release
Caveat Older extensions or add-ons may be incompatible with newer major versions; test in non-production environment first
