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 ========== [ 1 ] CVE-2007-2057 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2057 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200704-16.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
