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
-------------------------------------------------------------------
1 net-wireless/bluez-utils lt; 3.36 gt;= 3.36
2 net-wireless/bluez-libs lt; 3.36 gt;= 3.36
-------------------------------------------------------------------
2 affected packages on all of their 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 "gt;=net-wireless/bluez-utils-3.36=
"

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

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