Some of you might remember the mess caused by unfixed vulnerability in the old Widcomm bluetooth stack.

This caused quite a few vendors to switch to other bluetooth stacks. Unfortunately it seems that just switching to another vendor does not always help.

In the past month there has been two announcements of serious vulnerabilities in commonly used bluetooth stacks. Both the Toshiba stack and BlueNeighbors stack used by Ambicom were found vulnerable.

For Toshiba there is a patch available in aps.toshiba-tro.de but this may not work with OEM devices, and some vedors have not yet provided an update to their customers.

Ambicom updates are available at Ambicom.com but we do not have information whether they are already providing updated drivers or not.
