A flaw was found in the bluetooth specification that would allow an attacker within bluetooth radio range to abuse a protocol flaw which could allow key-overwrite in services.

Mitigation

As the bluetooth module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions:

echo "install bluetooth /bin/true" >> /etc/modprobe.d/disable-bluetooth.conf

The system will need to be restarted if the bluetooth modules are loaded. In most circumstances, the bluetooth kernel modules will be unable to be unloaded while any bluetooth interfaces are active and the protocol is in use.

If the system requires this module to work correctly, this mitigation may not be suitable.
