CVE-2006-3946

Estado: ModificadaAlta (7.5)—

WebCore en Apple Mac OS X 10.3.9 y 10.4 hasta 10.4.7 permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código de su elección mediante HTML artesanal que provoca un "error de gestión de memoria" en WebKit, posiblemente debido a un desbordamiento de buffer, como fue originalmente reportado para la función KHTMLParser::popOneBlock en Apple Safari 2.0.4 usando Javascript que cambia document.body.innerHTML dentro de una etiqueta DIV.
