script_tag(name:"insight", value:"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.
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 (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:
* Previously, it was impossible to configure 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. (BZ#906312)
All bind users are advised to upgrade to these updated packages, which
contain patches to correct this issue and add this enhancement. After
installing the update, the BIND daemon (named) will be restarted
automatically.");
