This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


Synopsis :

The remote SSH server may be affected by a format string
vulnerability.

Description :

The remote host is running SSH Tectia Server, a commercial SSH server.

According to its banner, the installed version of this software
contains a format string vulnerability in its sftp subsystem. A
remote, authenticated attacker may be able to execute arbitrary code
on the affected host subject to his privileges or crash the server
itself.

Solution :

As a temporary solution, disable the sftp subsystem as described in
the vendor advisory above. A better solution, though, is to upgrade
to SSH Tectia Server version 4.3.7 or 4.4.2 or later.
