ZDI-23-1900: (0Day) BlueZ Audio Profile AVRCP Stack-based Buffer Overflow Remote Code Execution Vulnerability

First published: Thu Dec 21 2023(Updated: )

This vulnerability allows network-adjacent attackers to execute arbitrary code via Bluetooth on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious device. The specific flaw exists within the handling of the AVRCP protocol. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root.
