The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-4951 advisory.

    Several vulnerabilities were discovered in Bluez, the Linux Bluetooth protocol stack. CVE-2020-26558 /     CVE-2021-0129 It was discovered that Bluez does not properly check permissions during pairing operation,     which could allow an attacker to impersonate the initiating device.

The remote host is affected by the vulnerability described in GLSA-202011-01 (BlueZ: Arbitrary code execution)

    It was discovered that there was a double-free vulnerability in Bluez       after the service discovery which occurs after a Bluetoth Low Energy       (BLE) connection has been established to a device.
  Impact :

    A remote attacker, by enticing a user to connect to a malicious GATT       server or device, could cause the execution of arbitrary code with the       privileges of the user running gatttool client or cause a Denial of       Service condition.
  Workaround :

    There is no known workaround at this time.

An update of the bluez package has been released.
