New! Plugin Severity Now Using CVSS v3

Synopsis

The remote CentOS host is missing one or more security updates.

Description

An update for bluez is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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.

Solution

Update the affected bluez packages.
