Description
This module exploits a buffer overflow in UltraVNC Viewer 1.0.2 Release.
If a malicious server responds to a client connection indicating a minor
protocol version of 14 or 16, a 32-bit integer is subsequently read from
the TCP stream by the client and directly provided as the trusted size for
further reading from the TCP stream into a 1024-byte character array on
the stack.
