1) Introduction
===============


GO-Global for Windows is a server-based thin-client solution.
It allows users to run 32-bit Windows applications remotely from a
server, the application runs entirely on the server but is displayed on
the client.

======
2) Bug
======


After the initial handshake where is specified the type of encryption
to use (_USERSA_), the application uses 16 bit fields for specifying
the length of the subsequent data blocks.
Both the client and the server use a small buffer which leads to a
buffer-overflow if an attacker uses a data block longer than its size.
Both server and clients are vulnerables.
