(RHSA-2016:0562) Important: bind security update

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 parsed signature records
  for DNAME records. By sending a specially crafted query, a remote attacker could
  use this flaw to cause named to crash. (CVE-2016-1286)

• A denial of service flaw was found in the way BIND processed certain control
  channel input. A remote attacker able to send a malformed packet to the control
  channel could use this flaw to cause named to crash. (CVE-2016-1285)

Red Hat would like to thank ISC for reporting these issues.
