   SUSE Security Update: Security update for bind
______________________________________________________________________________

Announcement ID: SUSE-SU-2015:0096-1
Rating: important
References: #908994
Cross-References: CVE-2014-8500
Affected Products:

______________________________________________________________________________

An update that fixes one vulnerability is now available.

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Also the rpz2 patch was removed as it is no longer maintained.
