BlueZ is a set of Bluetooth tools and system daemons for Linux.
It has been reported that the Bluetooth packet parser does not validate string length fields in SDP packets.
A physically proximate attacker using a Bluetooth device with an already established trust relationship could send specially crafted requests, possibly leading to arbitrary code execution or a crash. Exploitation may also be triggered by a local attacker registering a service record via a UNIX socket or D-Bus interface.
There is no known workaround at this time.
