Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

Summary

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.
A flaw was found in the way BIND handled trust anchor management. A remote attacker could use this flaw to cause the BIND daemon (named) to crash under certain conditions. (CVE-2015-1349)
Red Hat would like to thank ISC for reporting this issue.
All bind users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, the BIND daemon (named) will be restarted automatically.
