Detail
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. For the oldstable distribution (stretch), this problem has been fixed in version 5.43-2+deb9u2. For the stable distribution (buster), this problem has been fixed in version 5.50-1.2~deb10u1. We recommend that you upgrade your bluez packages.
