ISC BIND named contains a vulnerability where under certain situations it could incorrectly mark zone data as insecure.
According to ISC:
named, acting as a DNSSEC validator, was determining if an NS RRset is insecure based on a value that could mean either that the RRset is actually insecure or that there wasn't a matching key for the RRSIG in the DNSKEY RRset when resuming from validating the DNSKEY RRset.
Answers are marked incorrectly as insecure.
