Descripción
La función _gnutls_server_name_recv_params de lib/ext_server_name.c en libgnutls de gnutls-serv en GnuTLS versiones anteriores a la 2.2.4, no calcula correctamente el número de Nombre de Servidor en un mensaje Hello TLS 1.0 durante la gestión de extensiones, lo cual permite a atacantes remotos provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrariamente a través de un valor cero para la longitud de los Nombres de Servidores, lo que conlleva un desbordamiento de búfer en una sesión de reanudación de datos en la función pack_security_parameters, también conocida como GNUTLS-SA-2008-1-1.
