References: #743758 #858639 #908994

An update that solves two vulnerabilities and has one
errata is now available. It includes one version update.

Description:

This bind updated fixes the following two security issues:

*

A flaw in delegation handling could be exploited to put named into
an infinite loop. This has been addressed by placing limits on the number
of levels of recursion named will allow (default 7), and the number of
iterative queries that it will send (default 50) before terminating a
recursive query (CVE-2014-8500, bnc#908994). The recursion depth limit is
configured via the “max-recursion-depth”
option, and the query limit via the “max-recursion-queries” option.

*

A flaw when handling malformed NSEC3-signed zones could lead named
to a crash. (CVE-2014-0591, bnc#858639)

Additionally, a non-security bug has been fixed:

* Fix handling of TXT records in ldapdump (bnc#743758).
