Description Hanno Böck gentoo-dev

There isn't much more info, but the changelog of unbound 1.8.3 says:
	- Fix dns64 allocation in wrong region for returned internal queries.
	- And 1.8.3 release with this dns64 crash fix included.

Crashing a DNS resolver seems bad enough to treat it as a security issue.

1.8.3 is already in the tree, can we stabilize it?

We will go with =net-dns/unbound-1.9.0 which also contains patches from DNS flag day.
