"The remote NewStart CGSL host, running version MAIN 6.06, has bluez packages installed that are affected by a
vulnerability:

  - Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and
    establish an encrypted connection, and accept HID keyboard reports, potentially permitting injection of
    HID messages when no user interaction has occurred in the Central role to authorize such access. An
    example affected package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some cases, a CVE-2020-0556
    mitigation would have already addressed this Bluetooth HID Hosts issue. (CVE-2023-45866)

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