Security Fix(es) :
* An information-disclosure flaw was found in the bluetoothd
implementation of the Service Discovery Protocol (SDP). A specially
crafted Bluetooth device could, without prior pairing or user
interaction, retrieve portions of the bluetoothd process memory,
including potentially sensitive information such as Bluetooth
encryption keys. (CVE-2017-1000250)
