Description

Background

BlueZ is a set of Bluetooth tools and system daemons for Linux.

Description

It has been reported that the Bluetooth packet parser does not validate string length fields in SDP packets.

Impact

A physically proximate attacker using a Bluetooth device with an already established trust relationship could send specially crafted requests, possibly leading to arbitrary code execution or a crash. Exploitation may also be triggered by a local attacker registering a service record via a UNIX socket or D-Bus interface.

Workaround

There is no known workaround at this time.

Resolution

All bluez-utils users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-wireless/bluez-utils-3.36"

All bluez-libs users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-wireless/bluez-libs-3.36"
