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.
