Please Install the Updated Packages.

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 the libdns library. A remote attacker could use this flaw to send a specially-crafted DNS query to named that, when processed, would cause named to use an excessive amount of memory, or possibly crash. (CVE-2013-2266) Note: This update disables the syntax checking of NAPTR (Naming Authority Pointer) resource records. All bind97 users are advised to upgrade to these updated packages, which contain a patch to correct this issue. After installing the update, the BIND daemon (named) will be restarted automatically.
