bluez: memory leak in the SDP protocol

BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in sdpcstateallocbuf which allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object...
