CVE-2017-14315

High
Published: Translated: NVD NIST

Summary

In Apple iOS 7 through 9, there is a vulnerability related to the LEAP protocol that allows a large audio command to be sent to a targeted device, leading to a heap overflow with attacker-controlled data. This vulnerability enables full control over the device due to the high privileges of the Bluetooth stack in iOS.

Risk Assessment

An attacker can gain full access to the device, posing a serious threat to user data security and system integrity. The Bluetooth must be enabled in settings, which increases the risk for devices with Bluetooth turned on.

Recommendation

It is recommended to disable Bluetooth on devices running iOS 7 to 9 if it is not necessary. Additionally, consider upgrading to a newer version of the operating system to minimize the risk associated with this vulnerability.

Original NVD description (English source)

In Apple iOS 7 through 9, due to a BlueBorne flaw in the implementation of LEAP (Low Energy Audio Protocol), a large audio command can be sent to a targeted device and lead to a heap overflow with attacker-controlled data. Since the audio commands sent via LEAP are not properly validated, an attacker can use this overflow to gain full control of the device through the relatively high privileges of the Bluetooth stack in iOS. The attack bypasses Bluetooth access control; however, the default "Bluetooth On" value must be present in Settings.
