Just an update on this: It is patched in Ubuntu 14.04.1.

I have identified another bug in DiG which is yet to be patched in any versions of bind(I only just reported it now), which affects those that use ipv6.

megamansec@megamansec:~$ lsb_release -a

So, perhaps before pushing anything, wait for ISC to fix the most recent bug I identified.
