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

High Nessus Plugin ID 83670

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Also the rpz2 patch was removed as it is no longer maintained.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