Descriptions
BlueZ Audio Profile AVRCP Stack-based Buffer Overflow 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 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-19909.
Vulnerabilidad de ejecución remota de código de desbordamiento de búfer en la región stack de la memoria AVRCP de perfil de audio BlueZ. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario a través de Bluetooth en instalaciones afectadas de BlueZ. Se requiere la interacción del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe conectarse a un dispositivo malicioso. La falla específica existe en el manejo del protocolo AVRCP. El problema se debe a la falta de una validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en pila de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Fue ZDI-CAN-19909.
A flaw was found within the handling of the AVRCP protocol in BlueZ. This vulnerability allows network-adjacent attackers to execute arbitrary code via Bluetooth on affected installations of BlueZ.
