The browser engine in Mozilla Firefox 3 before 3.0.11, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.17 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) nsEventStateManager::GetContentState and nsNativeTheme::CheckBooleanAttr; (2) UnhookTextRunFromFrames and ClearAllTextRunReferences; (3) nsTextFrame::ClearTextRun; (4) IsPercentageAware; (5) PL_DHashTableFinish; (6) nsListBoxBodyFrame::GetNextItemBox; (7) AtomTableClearEntry, related to the atom table, DOM mutation events, and Unicode surrogates; (8) nsHTMLEditor::HideResizers; and (9) nsWindow::SetCursor, related to changing the cursor; and other vectors.

Glexia's TakeAutomated analysis

Security readout for executives and security teams

This is an old Mozilla browser-engine memory corruption issue. A malicious web page or browser-rendered content could crash affected applications and may allow code execution. It matters mainly where legacy Firefox, Thunderbird, or SeaMonkey versions are still present. Exposure is most likely in unmanaged legacy desktops, embedded systems, old Linux distributions, or archived virtual machines running the affected Mozilla versions. Modern supported browser and mail clients are unlikely to be exposed. Prioritize as a legacy technology risk. It is not currently supported by KEV evidence, but any remaining affected installations should be removed or isolated because the impact includes possible code execution. Mitigation focus: Upgrade to versions at or beyond the fixed releases named in the CVE.; Replace unsupported legacy Mozilla applications with currently supported browsers and mail clients.; Use vendor distribution advisories for package-specific update paths..
