A flaw in delegation handling could be exploited to put
|
|
|
|
|
|
<span class="command"><strong>named</strong></span> into an infinite loop, in which
|
|
|
|
|
|
each lookup of a name server triggered additional lookups
|
|
|
|
|
|
of more name servers. This has been addressed by placing
|
|
|
|
|
|
limits on the number of levels of recursion
|
|
|
|
|
|
<span class="command"><strong>named</strong></span> will allow (default 7), and
|
|
|
|
|
|
on the number of queries that it will send before
|
|
|
|
|
|
terminating a recursive query (default 50).

Two separate problems were identified in BIND's GeoIP code that
|
|
|
|
|
|
could lead to an assertion failure. One was triggered by use of
|
|
|
|
|
|
both IPv4 and IPv6 address families, the other by referencing
|
|
|
|
|
|
a GeoIP database in <code class="filename">named.conf</code> which was
|
|
|
|
|
|
not installed. Both are covered by CVE-2014-8680. [RT #37672]

|

|
<p>
|
2015-10-05 21:59:35 -07:00
|
|
|
|
A less serious security flaw was also found in GeoIP: changes
|
|
|
|
|
|
to the <span class="command"><strong>geoip-directory</strong></span> option in
|
|
|
|
|
|
<code class="filename">named.conf</code> were ignored when running
|
|
|
|
|
|
<span class="command"><strong>rndc reconfig</strong></span>. In theory, this could allow
|
|
|
|
|
|
<span class="command"><strong>named</strong></span> to allow access to unintended clients.

Unlike the existing DLZ and SDB interfaces, which provide a
|
|
|
|
|
|
limited subset of database functionality within BIND —
|
|
|
|
|
|
translating DNS queries into real-time database lookups with
|
|
|
|
|
|
relatively poor performance and with no ability to handle
|
|
|
|
|
|
DNSSEC-signed data — DynDB is able to fully implement
|
|
|
|
|
|
and extend the database API used natively by BIND.

A DynDB module could pre-load data from an external data
|
|
|
|
|
|
source, then serve it with the same performance and
|
|
|
|
|
|
functionality as conventional BIND zones, and with the
|
|
|
|
|
|
ability to take advantage of database features not
|
|
|
|
|
|
available in BIND, such as multi-master replication.

New quotas have been added to limit the queries that are
|
|
|
|
|
|
sent by recursive resolvers to authoritative servers
|
|
|
|
|
|
experiencing denial-of-service attacks. When configured,
|
|
|
|
|
|
these options can both reduce the harm done to authoritative
|
|
|
|
|
|
servers and also avoid the resource exhaustion that can be
|
|
|
|
|
|
experienced by recursives when they are being used as a
|
|
|
|
|
|
vehicle for such an attack.

When answering recursive queries, SERVFAIL responses can now be

|
|

|
cached by the server for a limited time; subsequent queries for
|
|
|
|
|
|
the same query name and type will return another SERVFAIL until
|
|
|
|
|
|
the cache times out. This reduces the frequency of retries
|
|
|
|
|
|
when a query is persistently failing, which can be a burden
|
|
|
|
|
|
on recursive serviers. The SERVFAIL cache timeout is controlled
|
2015-10-18 01:07:32 +00:00
|
|
|
|
by <code class="option">servfail-ttl</code>, which defaults to 1 second
|
2015-10-05 21:59:35 -07:00
|
|
|
|
and has an upper limit of 30.

The new <span class="command"><strong>rndc nta</strong></span> command can now be used to
|
|
|
|
|

set a "negative trust anchor" (NTA), disabling DNSSEC validation for
|
|

a specific domain; this can be used when responses from a domain
|
|
|
|
|
|
are known to be failing validation due to administrative error
|
|
|
|
|
|
rather than because of a spoofing attack. NTAs are strictly
|
|
|
|
|
|
temporary; by default they expire after one hour, but can be
|
|
|
|
|
|
configured to last up to one week. The default NTA lifetime
|
|
|
|
|
|
can be changed by setting the <code class="option">nta-lifetime</code> in
|
|
|

|
<code class="filename">named.conf</code>. When added, NTAs are stored in a

file (<code class="filename"><em class="replaceable"><code>viewname</code></em>.nta</code>)
|
|
|
|
|
|
in order to persist across restarts of the <span class="command"><strong>named</strong></span> server.

NXDOMAIN responses to queries of type DS are now cached separately

of type DS for such a zone could cause the zone apex to be cached

as NXDOMAIN, blocking all subsequent queries. (Note: This

change is only helpful when DNSSEC validation is not enabled.

The server could match a shorter prefix than what was
|
|
|
|
|
|
available in CLIENT-IP policy triggers, and so, an
|
|
|
|
|
|
unexpected action could be taken. This has been
|
|
|
|
|
|
corrected. [RT #39481]

The server could crash if a reload of an RPZ zone was

initiated while another reload of the same zone was

already in progress. [RT #39649]

Zones configured to use <span class="command"><strong>map</strong></span> format

master files can't be used as policy zones because RPZ
|
|
|
|

summary data isn't compiled when such zones are mapped into

memory. This limitation may be fixed in a future release,

but in the meantime it has been documented, and attempting

to use such zones in <span class="command"><strong>response-policy</strong></span>

statements is now a configuration error. [RT #38321]

will not be before BIND 9.13.0 has been released for 6 months.
