Unspecified vulnerability in 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, with
DNSSEC validation enabled and checking disabled (CD), allows remote
attackers to conduct DNS cache poisoning attacks by receiving a recursive
client query and sending a response that contains (1) CNAME or (2) DNAME
records, which do not have the intended validation before caching, aka Bug
20737. NOTE: this vulnerability exists because of an incomplete fix for
CVE-2009-4022.
