CVE-2015-2720

Estado: ModificadaMedia (4.4)—

La implementación de actualización en Mozilla Firefox anterior a 38.0 en Windows no asegura que el nombre de ruta para updater.exe corresponda con el directorio de la aplicación, lo que podría permitir a usuarios locales ganar privilegios a través de un fichero troyano.
