Title:	PowerDNS Authoritative Server Packet Cache Pollution DoS Vulnerability
Summary:	An issue has been found in PowerDNS Authoritative Server allowing a remote;user to craft a DNS query that will cause an answer without DNSSEC records to be inserted into the packet cache;and be returned to clients asking for DNSSEC records, thus hiding the presence of DNSSEC signatures for a specific;qname and qtype. For a DNSSEC-signed domain, this means that DNSSEC validating clients will consider the answer to;be bogus until it expires from the packet cache, leading to a denial of service.
