Descriptions

An issue was discovered in Squid 3.x and 4.x through 4.8 when the append_domain setting is used (because the appended characters do not properly interact with hostname length restrictions). Due to incorrect message processing, it can inappropriately redirect traffic to origins it should not be delivered to.

Se descubrió un problema en Squid versiones 2.x, 3.x y versiones 4.x hasta 4.8 cuando la configuración append_domain es usada (porque los caracteres añadidos no interactúan apropiadamente con las restricciones de longitud del nombre de host). Debido a un procesamiento incorrecto del mensaje, puede redireccionar inapropiadamente el tráfico a los orígenes a los que no debe ser enviado.
