SUSE SLED12 / SLES12 Security Update : bind (SUSE-SU-2015:0096-1)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

This update of bind to 9.9.6P1 fixes bugs and also 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.

Also the rpz2 patch was removed as it is no longer maintained.

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.
