Descriptions

hostapd 0.6.7 through 2.5 and wpa_supplicant 0.6.7 through 2.5 do not reject
and \r characters in passphrase parameters, which allows remote attackers to cause a denial of service (daemon outage) via a crafted WPS operation.

hostapd 0.6.7 hasta la versión 2.5 y wpa_supplicant 0.6.7 hasta la versión 2.5 no rechaza caracteres
y \r en parámetros passphrase, lo que permite a atacantes remotos provocar una denegación de servicio (corte de demonio) a través de una operación WPS manipulada.
