The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

Security Fix(es) :

* A denial of service flaw was found in the way BIND handled responses containing a DNAME answer. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. (CVE-2016-8864)

Red Hat would like to thank ISC for reporting this issue. Upstream acknowledges Tony Finch (University of Cambridge) and Marco Davids (SIDN Labs) as the original reporters.
