named in ISC BIND 9.7.2-P2 does not check all intended locations for allow-query ACLs, which might allow remote attackers to make successful requests for private DNS records via the standard DNS query mechanism.
ISC BIND before 9.7.2-P2, when DNSSEC validation is enabled, does not properly handle certain bad signatures if multiple trust anchors exist for a single zone, which allows remote attackers to cause a denial of service (daemon crash) via a DNS query.
ISC BIND 9.7.2 through 9.7.2-P1 uses an incorrect ACL to restrict the ability of Recursion Desired (RD) queries to access the cache, which allows remote attackers to obtain potentially sensitive information via a DNS query.
