Hi list, Please find attached a script (smtp-check-vulns.nse) which currently only checks for the Postfix SMTP Cyrus SASL authentication memory corruption CV-2011-1720 [1] The LOGIN mechanism seems also vulnerable, but as noted in the Postfix advisory [1], sending "AUTH PLAIN" after aborting the "AUTH LOGIN" request does not result in a memory corruption. I've only tested the CRAM-MD5 and NTLM mechanisms. The NTLM data structure will be corrupted and the Postfix smtpd will segfault after two tests using the DIGEST-MD5 mechanism. The checks for the other mechanisms are disabled, I don't have a config to test them. The script will segfault the smtpd child which runs with the 'postfix' user privileges. The script supports the submission protocol. You can add other checks, just put them in the 'AUTH_VULN' table. If I've enough time I'll try to check the sources and complete this table.
