CVE-2015-2712

Estado: ModificadaAlta (7.5)—

La implementación asm.js en Mozilla Firefox anterior a 38.0 no determina correctamente las longitudes de la memoria dinámica durante la identificación de casos en que la comprobación de límites puede saltarse con seguridad, lo que permite a atacantes remotos provocar operaciones de escritura fuera de rango y posiblemente obtener información sensible de la memoria de procesos a través de JavaScript manipulado.
