Doc Text:
A flaw was found in the bind package. This issue may allow an attacker to query in a DNS64 enabled resolver node with a domain name triggering a server-stale data, triggering a code assertion, and resulting in a crash of `named` processes. This can allow a remote unauthenticated user to cause a Denial Of Service in the DNS server.
