Bluez vulnerabilities

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.

BlueZ HID over GATT Profile Improper Access Control Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the HID over GATT Profile. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-25177.
