Description
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.
