CVE-2020-25187

Medtronic MyCareLink Smart 25000 is vulnerable when an authenticated attacker runs a debug command, which can be sent to the patient reader and cause a heap overflow event within the MCL Smart Patient Reader software stack. The heap overflow could allow an attacker to remotely execute code on the MCL Smart Patient Reader, potentially leading to control of the device
