GLSA-200711-09 : MadWifi: Denial of Service
Medium Nessus Plugin ID 27826
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200711-09 (MadWifi: Denial of Service)
Clemens Kolbitsch and Sylvester Keil reported an error when processing beacon frames with an overly large 'length' value in the 'xrates' element.
A remote attacker could act as an access point and send a specially crafted packet to an Atheros based wireless client, possibly resulting in a Denial of Service (kernel panic).
There is no known workaround at this time.
SolutionAll MadWifi users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-wireless/madwifi-ng-0.9.3.3'
