Updated bind package fixes security vulnerability

Updated bind packages fix security vulnerability: Because of a defect in handling queries for NSEC3-signed zones, BIND can crash with an “INSIST” failure in name.c when processing queries possessing certain properties. By exploiting this defect an attacker deliberately constructing a query with the right properties could achieve denial of service against an authoritative nameserver serving NSEC3-signed zones (CVE-2014-0591).
