CentOS Errata and Security Advisory CESA-2016:1945

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 constructed a response to a
    query that met certain criteria. A remote attacker could use this flaw to make
    named exit unexpectedly with an assertion failure via a specially crafted DNS
    request packet. (CVE-2016-2776)

Red Hat would like to thank ISC for reporting this issue.
