PowerDNS Security Advisory reports:
An issue has been found in the DNSSEC validation component of PowerDNS
Recursor, allowing an ancestor delegation NSEC or NSEC3 record to be used to
wrongfully prove the non-existence of a RR below the owner name of that
record. This would allow an attacker in position of man-in-the-middle to send
a NXDOMAIN answer for a name that does exist.
