Package: unbound
Version: 1.0.2-1
Severity: normal

Unbound seems to trust (and pass on to clients) extra/glue data in
responses from authoritative servers, even when this extra data
contradicts that held locally for a transparent zone.

Example:

Authoritative server has records:
foo.example.com A 192.168.1.1
bar.example.com CNAME a.example.com.

Unbound has the following in a transparent zone:
foo.example.com A 10.1.1.1


A query to unbound, `dig -t a bar.example.com @<unbound ip>` receives
the answer given by the authoritative server:

bar.example.com CNAME a.example.com.
foo.example.com A     192.168.1.1

This is at the very least counter-intuitive, at worst - who knows?
