"The remote host is running AXIGEN Mail Server, a messaging system for
Linux and BSD.
The POP3 server component of AXIGEN Mail Server contains a format
string vulnerability because it calls syslog() when logtypeis set to
'system'. In addition, the IMAP server component is affected by two
denial of service issues involving PLAIN and CRAM-MD5 authentication
methods. An unauthenticated, remote attacker can leverage these issues
to crash the IMAP service and possibly execute arbitrary code
remotely." );
