The function that processes the Hop-by-Hop extension header in IPv6 packets and its options lacks any checks against the length field of the header, allowing attackers to put the function into an infinite loop by supplying arbitrary length values."

La funci\u00f3n que procesa la cabecera de extensi\u00f3n Hop-by-Hop en los paquetes IPv6 y sus opciones carece de cualquier comprobaci\u00f3n contra el campo de longitud de la cabecera, lo que permite a los atacantes poner la funci\u00f3n en un bucle infinito suministrando valores de longitud arbitrarios"
