Description

With a specially crafted Python script, an attacker could send
continuous startMeasurement commands over an unencrypted Bluetooth
connection to the affected device. This would prevent the device from
connecting to a clinician's app to take patient readings and ostensibly
flood it with requests, resulting in a denial-of-service condition.
