Severity: High 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"
