This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of Sony XAV-9500ES devices. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability.\n\nThe specific flaw exists within the handling of Bluetooth L2CAP packets. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the device. Was ZDI-CAN-28990."

Esta vulnerabilidad permite a atacantes adyacentes a la red revelar información sensible en instalaciones afectadas de dispositivos Sony XAV-9500ES. Un atacante debe primero obtener la capacidad de emparejar un dispositivo Bluetooth malicioso con el sistema objetivo para explotar esta vulnerabilidad.\n\nEl fallo específico existe en el manejo de paquetes Bluetooth L2CAP. El problema se debe a la falta de validación adecuada de los datos proporcionados por el usuario, lo que puede resultar en una lectura más allá del final de un búfer asignado. Un atacante puede aprovechar esto en conjunto con otras vulnerabilidades para ejecutar código arbitrario en el contexto del dispositivo. Fue ZDI-CAN-28990."
