The Ubuntu security team deemed this advisory irrelevant for Ubuntu:15.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pdns-recursor package and not the pdns-recursor package as distributed by Ubuntu.
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.
