Descriptions

Bluetooth firmware or operating system software drivers in macOS versions before 10.13, High Sierra and iOS versions before 11.4, and Android versions before the 2018-06-05 patch may not sufficiently validate elliptic curve parameters used to generate public keys during a Diffie-Hellman key exchange, which may allow a remote attacker to obtain the encryption key used by the device.

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.
