The following errata report has been verified for RFC6672, "DNAME Redirection in the DNS". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata/eid5297 -------------------------------------- Status: Verified Type: Editorial Reported by: Pieter Lexis <pieter.lexis@powerdns.com> Date Reported: 2018-03-23 Verified by: Warren Kumari (Ops AD) (IESG) Section: 5.3.4.1 Original Text ------------- ;; Header: QR AA RCODE=3(NXDOMAIN) ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags: do; udp: 4096 ;; Question foo.bar.example.com. IN A ;; Authority bar.example.com. NSEC dub.example.com. A DNAME bar.example.com. RRSIG NSEC [valid signature] Corrected Text -------------- ;; Header: QR AA RCODE=3(NXDOMAIN) ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags: do; udp: 4096 ;; Question foo.bar.example.com. IN A ;; Authority bar.example.com. NSEC dub.example.com. A DNAME RRSIG NSEC bar.example.com. RRSIG NSEC [valid signature] Notes ----- The NSEC record in the original text would in no case be valid as it denies it's own existence and the existence of the RRSIG, while the text indicates that " the validator can see that it is a BOGUS reply from an attacker that collated existing records from the DNS to create a confusing reply". This indicates that NSEC and RRSIG should be set in the NSEC bitmap.
