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).

Security Issues:

   * CVE-2014-8500
