Estado: ModificadaMedia (5.5)—

En la función onResume del archivo VoicemailSettingsFragment.java, se presenta una posible manera de recuperar un identificador rastreable sin permisos debido a una falta de comprobación de permisos. Esto podría conllevar a una divulgación de información local sin ser necesarios privilegios de ejecución adicionales. Es requerida una interacción del usuario para su explotación.
