Updated bind packages fix security vulnerability:

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 Mageia default
configuration) or “dnssec-validation auto;” (CVE-2015-1349).
