Red Hat Security Advisory 2013-0550-01
Posted Feb 21, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-0550-01 - 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. DNS64 is used to automatically generate DNS records so IPv6 based clients can access IPv4 systems through a NAT64 server. A flaw was found in the DNS64 implementation in BIND when using Response Policy Zones. If a remote attacker sent a specially-crafted query to a named server that is using RPZ rewrite rules, named could exit unexpectedly with an assertion failure. Note that DNS64 support is not enabled by default.
