Descriptions

The watch implementation in the JavaScript engine in Mozilla Firefox before 46.0, Firefox ESR 38.x before 38.8, and Firefox ESR 45.x before 45.1 allows remote attackers to execute arbitrary code or cause a denial of service (generation-count overflow, out-of-bounds HashMap write access, and application crash) via a crafted web site.

La implementación de watch en el motor JavaScript en Mozilla Firefox en versiones anteriores a 46.0, Firefox ESR 38.x en versiones anteriores a 38.8 y Firefox ESR 45.x en versiones anteriores a 45.1 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (desbordamiento de generación de contador, acceso a escritura en HashMap fuera de límites y caída de aplicación) a través de un sitio web manipulado.
