Description Adam Mariš 2017-11-07 16:54:24 UTC 
A vulnerability in DNSSEC implementation of PowerDNS was found. Processing of wildcard synthesized NSEC records may result in improper validation for non-existance in some implementations of DNSSEC. While synthesis of NSEC records is allowed by RFC4592, the synthesized owner names should not be used in the NSEC processing.
