<description>
|
||
|
<p>It was discovered that the HID and HOGP profiles implementations in
|
||
|
BlueZ did not specifically require bonding between the device and the
|
||
|
host.

<impact type="high">
|
||
|
<p>A remote attacker with adjacent access could impersonate an existing HID
|
||
|
device, cause a Denial of Service condition or escalate privileges.
