CVE-2008-2317

Estado: ModificadaAlta (9.3)—

WebCore en Safari de Apple no realiza apropiadamente garbage collection de elementos de documentos JavaScript, lo que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de pila y bloqueo de aplicación) por medio de una referencia a la propiedad ownerNode de un objeto CSSStyleSheet copiado de un elemento STYLE, tal y como es demostrado originalmente en el iPhone anterior a la versión 2.0 y en el iPod touch anterior a la versión 2.0, de Apple, una vulnerabilidad diferente de CVE-2008-1590.
