Original description

The description as published by the source.

BlueZ sdp-xml.c type confusion via RegisterProfile(ServiceRecord) can crash bluetoothd (local DoS): a crafted nested ServiceRecord can corrupt the SDP XML parser stack so scalar union data is treated as a sequence pointer, allowing a local caller to crash bluetoothd.
