Vulnerability from fkie_nvd - Published: 2024-05-03 02:15 - 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 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.

La falla espec\u00edfica existe en el manejo del protocolo AVRCP. El problema se debe a la falta de una validaci\u00f3n adecuada de los datos proporcionados por el usuario, lo que puede provocar una escritura m\u00e1s all\u00e1 del final de un b\u00fafer asignado.
