The Ubuntu security team deemed this advisory irrelevant for Ubuntu:12.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libesmtp package and not the libesmtp package as distributed by Ubuntu.
libESMTP, probably 1.0.4 and earlier, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
