Crucial patch release for Red Hat Enterprise Linux 6 addresses a severe vulnerability. Update immediately to ensure your systems' safety!
Updated bind packages that fix one security issue are now available for Red Hat Enterprise Linux 6

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 denial of service flaw was found in BIND. A remote attacker could use this flaw to send a specially-crafted DNS query to named that, when processed, would cause named to crash when rejecting the malformed query. (CVE-2013-4854)
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.
