"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has bluez packages installed that are affected by
multiple vulnerabilities:

  - A bug in Bluez may allow for the Bluetooth Discoverable state being set to on when no Bluetooth agent is
    registered with the system. This situation could lead to the unauthorized pairing of certain Bluetooth
    devices without any form of authentication. Versions before bluez 5.51 are vulnerable. (CVE-2018-10910)

  - Improper access control in subsystem for BlueZ before version 5.54 may allow an unauthenticated user to
    potentially enable escalation of privilege and denial of service via adjacent access (CVE-2020-0556)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
