The remote Gentoo host is missing one or more security-related
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.
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.
There is no known workaround at this time.
