Mandriva Linux Security Advisory 2015-165 - By making use of maliciously-constructed zones or a rogue server, an attacker can exploit an oversight in the code BIND 9 uses to follow delegations in the Domain Name Service, causing BIND to issue unlimited queries in an attempt to follow the delegation. This can lead to resource exhaustion and denial of service.

Mandriva Linux Security Advisory MDVSA-2015:165
http://www.mandriva.com/en/support/security/
_______________________________________________________________________
Package : bind
Date : March 29, 2015
Affected: Business Server 2.0
_______________________________________________________________________
Problem Description:
Updated bind packages fix security vulnerabilities:
By making use of maliciously-constructed zones or a rogue server,
an attacker can exploit an oversight in the code BIND 9 uses to
follow delegations in the Domain Name Service, causing BIND to issue
unlimited queries in an attempt to follow the delegation. This can
lead to resource exhaustion and denial of service (up to and including
termination of the named server process) (CVE-2014-8500).
Jan-Piet Mens discovered that the BIND DNS server would crash when
processing an invalid DNSSEC key rollover, either due to an error
on the zone operator's part, or due to interference with network
traffic by an attacker. This issue affects configurations with the
directives "dnssec-lookaside auto;" (as enabled in the Mandriva
default configuration) or "dnssec-validation auto;" (CVE-2015-1349).
