CVE-2015-6771

Estado: ModificadaAlta (7.5)—

js/array.js en Google V8, como se utiliza en Google Chrome en versiones anteriores a 47.0.2526.73, no implementa correctamente ciertas operaciones de mapeo y filtro para arrays, lo que permite a atacantes remotos causar una denegación de servicio (acceso a memoria fuera de rango) o posiblemente tener otro impacto no especificado a través de código JavaScript manipulado.
