Descriptions

lighttpd before 1.4.26, and 1.5.x, allocates a buffer for each read operation that occurs for a request, which allows remote attackers to cause a denial of service (memory consumption) by breaking a request into small pieces that are sent at a slow rate.

lighttpd anterior a v1.4.26 y v1.5.x, reserva un búfer por cada operación de lectura para cada petición, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) rompiendo la petición en pequeños pedazos que son enviados a baja velocidad.
