GLSA-200704-15 : MadWifi: Multiple vulnerabilities

high Nessus Plugin ID 25060

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200704-15 (MadWifi: Multiple vulnerabilities)

 The driver does not properly process Channel Switch Announcement Information Elements, allowing for an abnormal channel change. The ieee80211_input() function does not properly handle AUTH frames and the driver sends unencrypted packets before WPA authentication succeeds.
 Impact :

 A remote attacker could send specially crafted AUTH frames to the vulnerable host, resulting in a Denial of Service by crashing the kernel. A remote attacker could gain access to sensitive information about network architecture by sniffing unencrypted packets. A remote attacker could also send a Channel Switch Count less than or equal to one to trigger a channel change, resulting in a communication loss and a Denial of Service.
 Workaround :

 There is no known workaround at this time.

Solution

All MadWifi users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-wireless/madwifi-ng-0.9.3'
