Descriptions
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.
Perfil de audio BlueZ AVRCP Validación inadecuada de la vulnerabilidad de ejecución remota de código del índice de matriz. 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 los datos proporcionados por el usuario, lo que puede provocar una escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Fue ZDI-CAN-19908.
A vulnerability was found in the BlueZ Audio Profile AVRCP, stemming from the improper validation of array indices. This flaw resides in the AVRCP protocol handling and arises due to inadequate validation of user-supplied data. Consequently, it may lead to writing beyond the bounds of an allocated buffer. This flaw possibly allows a network-adjacent attacker to execute code within the root context via Bluetooth.
