ISC BIND 9 DNSSEC Cache Poisoning Vulnerability
https://www.isc.org/node/504

A nameserver with DNSSEC validation enabled may incorrectly add records to its cache from the additional section of responses received during resolution of a recursive client query. This behavior only occurs when processing client queries with checking disabled (CD) at the same time as requesting DNSSEC records (DO).
