Synopsis :

The remote SMTP server has a buffer overflow vulnerability.

Description :

The remote host appears to be running NetManage Chameleon SMTPd.

This version of the software has a remote buffer overflow
vulnerability. Nessus crashed the service by issuing a long argument
to the HELP command. A remote attacker could exploit this issue to
crash the service, or possibly execute arbitrary code.

There is also a buffer overflow related to the HELO command, but
Nessus has not checked for this issue.
