Synopsis
========

Kismet is vulnerable to multiple issues potentially resulting in the
execution of arbitrary code.

Background
==========

Kismet is an 802.11 Layer 2 wireless network detector, sniffer, and
intrusion detection system.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /   Vulnerable   /                Unaffected
    -------------------------------------------------------------------
  1  net-wireless/kismet      < 2005.08.1                 >= 2005.08.1

Description
===========

Kismet is vulnerable to a heap overflow when handling pcap captures and
to an integer underflow in the CDP protocol dissector.

Impact
======

With a specially crafted packet an attacker could cause Kismet to
execute arbitrary code with the rights of the user running the program.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Kismet users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-wireless/kismet-2005.08.1"
