Description Adam Mariš 2016-07-07 13:18:32 UTC 
It was found that knot 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.
