Red Hat Security Advisory 2013-0690-01 - The Berkeley Internet Name Domain is an implementation of the Domain Name System protocols. BIND includes a DNS server ; a resolver library ; 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. Note: This update disables the syntax checking of NAPTR resource records.
