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.
