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.
