Description

A flaw was found in BlueZ. Insufficient validation of packet length fields in GetFolderItems responses within the Audio/Video Remote Control Profile (AVRCP) implementation allows a malicious Bluetooth device within range to cause an out-of-bounds memory read. This vulnerability, affecting the parse_media_element() and parse_media_folder() functions, can lead to a crash of the bluetoothd daemon, resulting in a Denial of Service (DoS). It could also potentially expose sensitive heap memory contents. Exploitation requires user interaction to pair with the malicious device.
