bluez vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 23.10
- Ubuntu 23.04
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)

Summary:

BlueZ could be made to give a physically proximate attacker keyboard and
mouse control of a computer.

Software Description:
- bluez: Bluetooth tools and daemons

Details:

It was discovered that BlueZ did not properly restrict non-bonded devices
from injecting HID events into the input subsystem. This could allow a
physically proximate attacker to inject keystrokes and execute arbitrary
commands whilst the device is discoverable.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 23.10:
   bluez                           5.68-0ubuntu1.1
