More specifically, it appears that mode 7 itself is, in some sense, deprecated (e.g., "mode7 ... Enables processing of NTP mode 7 implementation-specific requests which are used by the deprecated ntpdc program" on the http://www.eecis.udel.edu/~mills/ntp/html/miscopt.html page and "functionally deprecating ntpdc" on the http://support.ntp.org/bin/view/Main/SoftwareDownloads page). If so, then we do not feel that there is a requirement for the documentation to precisely specify the effect of a command-line option on a deprecated feature. The -A documentation doesn't directly make a false statement about authentication within mode 7; it simply does not discuss mode 7. If mode 7 itself isn't deprecated, and there is a supported use case in which the user may choose to enable both mode 7 and the -A option, then announcing the behavior/documentation mismatch as a vulnerability is probably more useful. - -- CVE assignment team, MITRE CVE Numbering Authority M/S M300 202 Burlington Road, Bedford, MA 01730 USA [ PGP key available through http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (SunOS) iQEcBAEBAgAGBQJVVOBzAAoJEKllVAevmvmsy4oH/REWyDXtOBOoJL5lYtj6zroV DATBhEgJTGSK7m7zc5Z1sqGGEGXNthghS8VGysc4T1vbkgKVO0hpATMzHdZb6L6R rNGggnTpHxoubpKRt+flURxCBzMta0w9brQb2vXxUvh4RYy+6MklDqGQofQA3ELB 9rZW6wkMK3KYms00HJGrGkIutxcVe+1/1At6htLGlQo3wEuY5ORHdlxmUxHaXBos 99fyRa1rR8ZzrN1EKWgh62WUhetvauqASFlYXdhNcqUgySlzIfMrAlFpLUyvTIGn TjTYgf+XAvlQLmnPjKV48IeY/g2BE8MHO61loTCX5fBeYMT3lzyl2PVDx6sIN9s= =MpGY -----END PGP SIGNATURE-----
