"This bind update to version 9.6-ESV-R11-W1 fixes the following
security issue :

  - 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.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
