Pe 2.4.3 Buffer Overflow

`# Exploit Author: Juan Sacco - http://www.exploitpack.com <  
[email protected]>  
# Program: Pe - Haiku OS  
# Tested on: Haiku OS Alpha x86  
#  
# Description: Pe v2.4.3 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.  
#

# Tested on: Haiku-OS Alpha Pe 2.4.3
