The remote FreeBSD host is missing a security-related update.


Unbound developer reports :

Unbound crashes when confronted with a non-standard response from a server for a domain. This domain produces duplicate RRs from a certain type and is DNSSEC signed. Unbound also crashes when confronted with a query that eventually, and under specific circumstances, resolves to a domain that misses expected NSEC3 records.
