Ok, is there an exploit for this to test?

I had a look at

ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/tcpfix.patch and
ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/tcpfix.patch

which where referenced in the CERT as solution for the exploit. And I
*think* this is already in

$NetBSD: ip_input.c,v 1.76 1998/12/19 02:46:12 thorpej Exp $

which is NetBSD-current and

$NetBSD: ip_input.c,v 1.53.2.4 1998/11/15 19:18:13 cgd Exp $

which is NetBSD-1.3.3.

But then I am no expert or guru, so someone with a better clue might
care to speak.
