BIND NXT Bug Vulnerability (fwd)

[Steven Pritchard <steve@silug.org>]

There's an exploit for this now, so if you are running bind 8.x, you
probably want to upgrade.  (For those of you running Red Hat 6.0, the
updates mirror on ftp.silug.org actually has the rpms, which amazes me
because mirror has been consistently failing for weeks now...)
