The browser engine in Mozilla Firefox before 2.0.0.12, Thunderbird before 2.0.0.12, and SeaMonkey before 1.1.8 allows remote attackers to cause a denial of service (crash) and possibly trigger memory corruption via vectors related to the (1) nsTableFrame::GetFrameAtOrBefore, (2) nsAccessibilityService::GetAccessible, (3) nsBindingManager::GetNestedInsertionPoint, (4) nsXBLPrototypeBinding::AttributeChanged, (5) nsColumnSetFrame::GetContentInsertionFrame, and (6) nsLineLayout::TrimTrailingWhiteSpaceIn methods, and other vectors.

Technical summary

dbcve analysis · high confidence

Memory corruption vulnerability in the Mozilla browser engine affecting Firefox <2.0.0.12, Thunderbird <2.0.0.12, and SeaMonkey <1.1.8. Multiple frame and service methods (nsTableFrame::GetFrameAtOrBefore, nsAccessibilityService::GetAccessible, nsBindingManager::GetNestedInsertionPoint, nsXBLPrototypeBinding::AttributeChanged, nsColumnSetFrame::GetContentInsertionFrame, and nsLineLayout::TrimTrailingWhiteSpaceIn) allow remote attackers to cause denial of service via crash and potentially achieve memory corruption.

MitigationUpgrade to Firefox 2.0.0.12, Thunderbird 2.0.0.12, SeaMonkey 1.1.8 or later. This is a patch-upgrade scenario with no configuration changes required.

dbcve checks

Work through these to decide whether this CVE applies to you.

Identify installed Mozilla product

Check for presence of Firefox, Thunderbird, or SeaMonkey executables. On Linux: which firefox thunderbird seamonkey. On Windows: check Program Files directories. On macOS: check /Applications folder.

Affected if Any of Firefox, Thunderbird, or SeaMonkey is installed
Check Firefox version

Run 'firefox --version' or open Firefox, go to Help > About Firefox. Record the full version number displayed (e.g., 2.0.0.11).

Affected if Version is 2.0.0.11 or earlier (any 2.0.0.x version below 2.0.0.12)
Check Thunderbird version

Run 'thunderbird --version' or open Thunderbird, go to Help > About Thunderbird. Record the full version number displayed (e.g., 2.0.0.11).

Affected if Version is 2.0.0.11 or earlier (any 2.0.0.x version below 2.0.0.12)
Check SeaMonkey version

Run 'seamonkey --version' or open SeaMonkey, go to Help > About SeaMonkey. Record the full version number displayed (e.g., 1.1.7).

Affected if Version is 1.1.7 or earlier (any 1.1.x version below 1.1.8)

The environment is affected if any installed Mozilla product (Firefox <=2.0.0.11, Thunderbird <=2.0.0.11, or SeaMonkey <=1.1.7) matches the vulnerable version range.

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

Remediation

dbcve · scoped

Upgrade available Upgrade to a release after 2.0.0.11

Interim mitigation

Upgrade to Firefox 2.0.0.12, Thunderbird 2.0.0.12, SeaMonkey 1.1.8 or later. This is a patch-upgrade scenario with no configuration changes required.

Recommended fix High confidence

Firefox 2.0.0.12, Thunderbird 2.0.0.12, or SeaMonkey 1.1.8 (depending on product)

Upgrade Firefox to version 2.0.0.12
Upgrade Thunderbird to version 2.0.0.12
Upgrade SeaMonkey to version 1.1.8

Caveat These are legacy, unsupported product versions from 2008. The entire Firefox 2.x and Thunderbird 2.x product lines are obsolete and no longer receive security updates. Users should migrate to modern supported versions.

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.
