CVE-2016-6173 [HIGH] CVE-2016-6173 nsd: Improper restriction of zone size limit
CVE-2016-6173 nsd: Improper restriction of zone size limit
It was found that NSD does not implement reasonable restrictions for zone sizes. This allows an explicitly configured primary DNS server for a zone to crash a secondary DNS server, affecting service of other zones hosted on the same secondary server.
