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.\n\nThe 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.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar c\u00f3digo arbitrario en instalaciones afectadas de BlueZ.

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.
