Descriptions
BlueZ OBEX Library Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device.
The specific flaw exists within the handling of OBEX protocol parameters. 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 root. Was ZDI-CAN-20937.
Vulnerabilidad de divulgación de información de lectura fuera de los límites de la librería BlueZ OBEX. Esta vulnerabilidad permite a atacantes adyacentes a la red revelar información confidencial sobre las instalaciones afectadas de BlueZ. Se requiere la interacción del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe conectarse a un dispositivo Bluetooth malicioso. La falla específica existe en el manejo de los parámetros del protocolo OBEX. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar una lectura más allá del final de un búfer asignado. Un atacante puede aprovechar esto junto con otras vulnerabilidades para ejecutar código arbitrario en el contexto de la raíz. Era ZDI-CAN-20937.
