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 < 3.36 >= 3.36

2 net-wireless/bluez-libs < 3.36 >= 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 ">=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"
