The function that processes IPv6 headers does not check the lengths of extension header options, allowing attackers to put this function into an infinite loop with crafted length values."

La funci\u00f3n que procesa las cabeceras de IPv6 no comprueba las longitudes de las opciones de las cabeceras de extensi\u00f3n, lo que permite a los atacantes poner esta funci\u00f3n en un bucle infinito con valores de longitud manipulados"
