NVD Description

Note: Versions mentioned in the description apply only to the upstream bluez package and not the bluez package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

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.
