Summary

bluez security update

Details

This package provides all utilities for use in Bluetooth applications. The BLUETOOTH trademarks are owned by Bluetooth SIG, Inc., U.S.A.

Security Fix(es):

bluetoothd from bluez incorrectly saves adapters' Discoverable status when a device is powered down, and restores it when powered up. If a device is powered down while discoverable, it will be discoverable when powered on again. This could lead to inadvertent exposure of the bluetooth stack to physically nearby attackers.(CVE-2021-3658)

Severity

7.5 (High)
