| ISC BIND 9.0.x through 9.3.x, 9.4 before 9.4.3-P5, 9.5 before
9.5.2-P2, 9.6 before 9.6.1-P3, and 9.7.0 beta does not properly
validate DNSSEC (1) NSEC and (2) NSEC3 records, which allows remote
attackers to add the Authenticated Data (AD) flag to a forged NXDOMAIN
response for an existing domain.
