			Un pobrecito hablador nos cuenta: <EM>«[<A href="http://www.kriptopolis.org/el-pache-dns-no-resuelve-el-problema">Vía Kriptópolis</A>] Por lo visto el <A href="http://barrapunto.com/mainpage/08/08/07/0851246.shtml?tid=85">parche de seguridad</A> para la <A href="http://barrapunto.com/mainpage/08/07/09/0849236.shtml?tid=15">vulnerabilidad del DNS</A> no resuelve el problema del envenenamiento de la caché. El ruso Yevgueni Poliakov <A href="http://tservice.net.ru/~s0mbre/blog/devel/networking/dns/2008_08_08.html">ha demostrado que continúa siendo vulnerable</A>. Recordemos que no se trata de un bug exclusivo de BIND, sino del sistema DNS en general. <A href="http://www.dnssec.net/">DNSSEC</A> no es una solución definitiva pero funciona a juicio de Poliakov, aunque a DJ Bernstein no le gusta.  Pero incluso el DJBDNS de Bernstein, considerado el servidor DNS más seguro, <A href="http://tservice.net.ru/~s0mbre/blog/devel/networking/dns/2008_08_09.html">es igualmente vulnerable</A> según afirma Poliakov, pese a que el <A href="http://www.nytimes.com/2008/08/09/technology/09flaw.html">NYT diga que no lo es</A>.»</EM>
