Wanted to double-check dhcp is really affected by this bind bug and yes, dhcp can call the fixed answer_response() function through:

dns_client_startupdate -> startupdate -> send_update -> update_done -> dns_request_getresponse -> dns_message_parse -> getquestions -> findname -> fctx_finddone -> fctx_try -> fctx_query -> resquery_send -> resquery_response -> answer_response

dns_client_startupdate() gets called by dhclient & dhcpd (tested on rhel8 as bind libs are still dynamically loaded there):

~~~
# readelf --dyn-syms --wide /usr/sbin/dhcpd | grep dns_client_startupdate
   165: 0000000000000000     0 FUNC    GLOBAL DEFAULT  UND dns_client_startupdate
# readelf --dyn-syms --wide /usr/sbin/dhclient | grep dns_client_startupdate
   111: 0000000000000000     0 FUNC    GLOBAL DEFAULT  UND dns_client_startupdate
#
~~~
