Vulnerability from fkie_nvd - Published: 2024-05-03 03:16 - Updated: 2025-11-04 17:15
Severity ?
8.0 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
BlueZ Phone Book Access Profile Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code 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 the Phone Book Access profile. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20936.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar c\u00f3digo arbitrario en 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 del perfil de acceso a la agenda telef\u00f3nica. El problema se debe a la falta de una validaci\u00f3n adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un b\u00fafer basado en mont\u00f3n de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto de la ra\u00edz. Era ZDI-CAN-20936."
