Description :

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.
