MadWifi xrates denial of service
|madwifi-xrates-dos (37182)||Medium Risk|
MadWifi is vulnerable to a denial of service, caused by an error in the handling of beacon frames. By sending a specially-crafted beacon frame containing an overly large length value in the xrates, a remote attacker could cause the driver to exit resulting in a kernel panic.
