A flaw was found in the DNS64 implementation in BIND when using Response Policy Zones (RPZ). 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. (CVE-2012-5689)
This update also adds the following enhancement :
After installing the update, the BIND daemon (named) will be restarted automatically.

This update also adds the following enhancement :
- Previously, it was impossible to configure the the
maximum number of responses sent per second to one
client. This allowed remote attackers to conduct traffic
amplification attacks using DNS queries with spoofed
source IP addresses. With this update, it is possible to
use the new 'rate-limit' configuration option in
named.conf and configure the maximum number of queries
which the server responds to. Refer to the BIND
documentation for more details about the 'rate-limit'
option.
After installing the update, the BIND daemon (named) will be restarted
automatically."
