The Berkeley Internet Name Domain is an implementation of the Domain Name System protocols. BIND includes a DNS server ; a resolver library ; and tools for verifying that the DNS server is operating correctly. Security Fix: * A denial of service flaw was found in the way BIND handled a query response containing CNAME or DNAME resource records in an unusual order. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. * A denial of service flaw was found in the way BIND handled query requests when using DNS64 with "break-dnssec yes" option. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS request. Red Hat would like to thank ISC for reporting these issues. Upstream acknowledges Oleg Gorokhov as the original reporter of CVE-2017-3136.
