Title: Aircrack-ng: Remote execution of arbitrary code
Date: April 22, 2007
Bugs: #174340
ID: 200704-16

Synopsis
========
Aircrack-ng contains a buffer overflow that could lead to the remote
execution of arbitrary code with root privileges.
Background
==========
Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can
recover keys once enough data packets have been captured.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-wireless/aircrack-ng < 0.7-r2 >= 0.7-r2
Description
===========
Jonathan So reported that the airodump-ng module does not correctly
check the size of 802.11 authentication packets before copying them
into a buffer.
Impact
======
A remote attacker could trigger a stack-based buffer overflow by
sending a specially crafted 802.11 authentication packet to a user
running airodump-ng with the -w (--write) option. This could lead to
the remote execution of arbitrary code with the permissions of the user
running airodump-ng, which is typically the root user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Aircrack-ng users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-wireless/aircrack-ng-0.7-r2"
References
==========
