I recently received a question from a customer about CVE-201305211, the monlist amplification attack. Specifically they asked if the attack affected xntpd. They had another vendor that said no, that the attack only affects ntpd. This surprised me since as far as I know the monlist mechanism is the same in xntpd. I thought the vendor was merely incorrect. However, I then read the CERT and NIST versions of the CVE and there is no mention of xntpd. Indeed, a literal reading of the CVE does indeed imply that xntpd is not vulnerable.

I don't think I am wrong about xntpd being vulnerable. If I am, please correct me. But if I am not, we should probably see about getting the CVE amended.
