"It was reported that the BlueZ's HID and HOGP profile implementations
don't specifically require bonding between the device and the host.
Malicious devices can take advantage of this flaw to connect to a
target host and impersonate an existing HID device without security or
to cause an SDP or GATT service discovery to take place which would
allow HID reports to be injected to the input subsystem from a
non-bonded source.

For the HID profile an new configuration option (ClassicBondedOnly) is
introduced to make sure that input connections only come from bonded
device connections. The options defaults to 'false' to maximize device
compatibility.

Note that as a result of the significant changes between the previous
version in Jessie (based on upstream release 5.23) and the available
patches to address this vulnerability, it was decided that a backport
of the bluez package from Debian 9 'Stretch' was the only viable way
to address the referenced vulnerability.

For Debian 8 'Jessie', this problem has been fixed in version
5.43-2+deb9u2~deb8u1.

We recommend that you upgrade your bluez packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."

    It was discovered that the HID and HOGP profiles implementations in
      BlueZ did not specifically require bonding between the device and the
      host.
  
Impact :

    A remote attacker with adjacent access could impersonate an existing HID
      device, cause a Denial of Service condition or escalate privileges.
  
Workaround :

    There is no known workaround at this time."
