The resolver in PowerDNS Recursor (aka pdns_recursor) 3.3 overwrites cached
server names and TTL values in NS records during the processing of a
response to an A record query, which allows remote attackers to trigger
continued resolvability of revoked domain names via a “ghost domain names”
attack.
