CVE-2016-2120

An issue has been found in PowerDNS Authoritative Server versions up to and
including 3.4.10, 4.0.1 allowing an authorized user to crash the server by
inserting a specially crafted record in a zone under their control then
sending a DNS query for that record. The issue is due to an integer
overflow when checking if the content of the record matches the expected
size, allowing an attacker to cause a read past the buffer boundary.
