Patch bind to pluig Kaminsky DNS vulnerability for FC7?

[Mike C]

Does anyone know if there is an easy way to fix bind (bind-chroot) running 
in an old machine running FC7 so that it offers the same protection as
bind-chroot-9.5.0-28.P1.fc8
and
bind-9.5.0-33.P1.fc9.i386
??

Can one use the src rpm for F8 and re-configure it for FC7?

I guess there are still quite a lot of servers in use that are running
EOLed Fedoras.
