CVE-2010-1121

Estado: ModificadaAlta (10)—
Firefox de Mozilla versiones 3.6.x anteriores a 3.6.3, no administra apropiadamente los ámbitos de los nodos DOM que son movidos de un documento a otro, lo que permite a los atacantes remotos conducir ataques de uso de memoria previamente liberada y ejecutar código arbitrario por medio de vectores no especificados que implican una interacción inapropiada con garbage collection, como es demostrado por Nils durante una competencia de Pwn2Own en CanSecWest 2010.
