CVE-2018-5383

El firmware bluetooth o los controladores de software del sistema operativo en versiones de macOS anteriores a la 10.13, versiones High Sierra e iOS anteriores a la 11.4 y versiones de Android anteriores al parche del 05/06/2018, podrían no validar lo suficiente parámetros de curva elíptica empleados para generar claves públicas durante un intercambio de claves Diffie-Hellman, lo que podría permitir que un atacante remoto obtenga la clave de cifrado empleada por el dispositivo.

A vulnerability in Bluetooth pairing potentially allows an attacker with physical proximity (within 30 meters) to gain unauthorized access via an adjacent network, intercept traffic and send forged pairing messages between two vulnerable Bluetooth devices. This may result in information disclosure, elevation of privilege and/or denial of service.

Eli Biham and Lior Neumann discovered that the Bluetooth implementation in the Linux kernel did not properly validate elliptic curve parameters during Diffie-Hellman key exchange in some situations. An attacker could use this to expose sensitive information. It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. An attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
