CVE-2014-7914

Estado: ModificadaAlta (8.1)—

En el archivo btif/src/btif_dm.c en Android versiones anteriores a 5.1, no aplica apropiadamente la naturaleza temporal de emparejar Bluetooth, lo que permite a atacantes remotos asistidos por el usuario omitir las restricciones de acceso previstas mediante paquetes Bluetooth diseñados luego del aprovechamiento de una etiqueta NFC diseñada
