Doc Type: If docs needed, set a value
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.

Description Marco Benatto 2024-02-12 18:07:13 UTC 
A bad interaction between DNS64 and serve-stale may cause named to crash with an assertion failure during recursive resolution, when both of these features are enabled.
