Descriptions

The http_request_split_value function in request.c in lighttpd before 1.4.32 allows remote attackers to cause a denial of service (infinite loop) via a request with a header containing an empty token, as demonstrated using the "Connection: TE,,Keep-Alive" header.

La función http_request_split_value en request.c en lighttpd en versiones anteriores a 1.4.32 permite a atacantes remotos provocar una denegación de servicio (bucle infinito) a través de una petición con una cabecera que contiene un token vacío, tal como se demuestra utilizando la cabecera "Connection: TE,,Keep-Alive".
