Description From 2007-04-02 23:21:11
Some vulnerabilities have been reported in MadWifi, which can be exploited by
malicious people to gain knowledge of potentially sensitive information or cause
a DoS (Denial of Service).

1) An error within the "ieee80211_input()" function when handling AUTH frames
from IBSS nodes can be exploited to cause a kernel crash by sending specially
crafted AUTH frames.

Successful exploitation may require that the "Ad-Hoc" mode is used.

2) MadWifi does not correctly handle Channel Switch Announcements. This can be
exploited to force a channel switch thus interrupting the communication by
injecting a Channel Switch Announcement with "CS Count" set to 1 or less.

3) An error within ieee80211_output.c may cause unencrypted packets to be sent
before the WPA authentication is completed. This can be exploited to gain
knowledge of certain sensitive information, which may be leveraged for further

The vulnerabilities are reported in versions prior to 0.9.3.

Update to version 0.9.3.
