TightVNC Viewer < 1.3.10 Multiple Integer Overflows

This script is Copyright (C) 2009-2015 Tenable Network Security, Inc.


Synopsis :

The remote Windows host has an application that is affected by
multiple integer overflows.

Description :

The installed version of TightVNC Viewer is earlier than 1.3.10. Such
versions reportedly miscalculate a buffer size on the heap. If an
attacker can trick a user on the remote host into connecting to a
malicious server, he can probably exploit this issue using specially
crafted messages to execute code on the affected host subject to the
user's privileges.
