BIND includes a DNS server (named); a resolverlibrary (routines for applications to use when interfacing with DNS); andtools for verifying that the DNS server is operating correctly.A denial of service flaw was found in the way BIND parsed signature recordsfor DNAME records. By sending a specially crafted query, a remote attackercould use this flaw to cause named to crash. (CVE-2016-1286)A denial of service flaw was found in the way BIND processed certaincontrol channel input. A remote attacker able to send a malformed packet tothe 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.All bind97 users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues.
