RHEL 6 / 7 : bluez (RHSA-2017:2685)

medium Nessus Plugin ID 103172

Language:

Synopsis

The remote Red Hat host is missing a security update for bluez.

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2685 advisory.

The bluez packages contain the following utilities for use in Bluetooth applications: hcitool, hciattach, hciconfig, bluetoothd, l2ping, start scripts (Red Hat), and pcmcia configuration files.

Security Fix(es):

* An information-disclosure flaw was found in the bluetoothd implementation of the Service Discovery Protocol (SDP). A specially crafted Bluetooth device could, without prior pairing or user interaction, retrieve portions of the bluetoothd process memory, including potentially sensitive information such as Bluetooth encryption keys. (CVE-2017-1000250)

Red Hat would like to thank Armis Labs for reporting this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL bluez package based on the guidance in RHSA-2017:2685.
