  "title": "bluez: BlueZ Audio Profile AVRCP Improper Validation of Array Index Remote Code Execution Vulnerability",
  "description": "BlueZ Audio Profile AVRCP Improper Validation of Array Index Remote Code Execution Vulnerability. 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 user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-19908.",
