Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference via the ResponseReverter. An attacker can cause the application to panic and degrade availability or crash the process by sending a specially crafted DNS query that triggers a nil pointer dereference when a downstream plugin returns a response with no OPT record.
Note: This is only exploitable if the debug directive disables recovery.
