Vulnerability from fkie_nvd - Published: 2024-05-03 03:16 - Updated: 2025-07-08 16:27
Severity ?
5.7 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Summary
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.

Esta vulnerabilidad permite a atacantes adyacentes a la red revelar informaci\u00f3n confidencial sobre las instalaciones afectadas de BlueZ. Se requiere la interacci\u00f3n del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe conectarse a un dispositivo Bluetooth malicioso. La falla espec\u00edfica existe en el manejo de los par\u00e1metros del protocolo OBEX. El problema se debe a la falta de una validaci\u00f3n adecuada de los datos proporcionados por el usuario, lo que puede provocar una lectura m\u00e1s all\u00e1 del final de un b\u00fafer asignado. Un atacante puede aprovechar esto junto con otras vulnerabilidades para ejecutar c\u00f3digo arbitrario en el contexto de la ra\u00edz. Era ZDI-CAN-20937."
