Descriptions
The Curl_input_negotiate function in http_negotiate.c in libcurl 7.10.6 through 7.21.6, as used in curl and other products, always performs credential delegation during GSSAPI authentication, which allows remote servers to impersonate clients via GSSAPI requests.
La función Curl_input_negotiate en http_negotiate.c en libcurl v7.10.6
a v7.21.6, tal y como se utiliza en curl y otras aplicaciones, siempre lleva a cabo
delegación de credenciales durante la autenticación GSSAPI, lo que permite a
hacerse pasar por clientes legitimos a servidores remotos a través de peticiones GSSAPI.
