GLSA 200903-29: BlueZ: Arbitrary code execution

http://security.gentoo.org/

Severity:	normal
Title:	BlueZ: Arbitrary code execution
Date:	03/16/2009
Bugs:	#230591
ID:	200903-29

Synopsis

Insufficient input validation in BlueZ may lead to arbitrary code execution or a Denial of Service.

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-wireless/bluez-utils	< 3.36	>= 3.36	All supported architectures
net-wireless/bluez-libs	< 3.36	>= 3.36	All supported architectures

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"
