BlueZ A2DP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability. The specific flaw exists within the handling of the stream endpoints. 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. Was ZDI-CAN-29429.

Improper buffer restrictions in BlueZ may allow an unauthenticated user to potentially enable denial of service via adjacent access. This affects all Linux kernel versions that support BlueZ.

Improper access control in BlueZ may allow an unauthenticated user to potentially enable information disclosure via adjacent access.

Improper input validation in BlueZ may allow an unauthenticated user to potentially enable escalation of privilege via adjacent access.
