Time to get aware of security concerns about Linux on 390. The last issue of the phrack magazine (a famous hacker magazine) has an article on how to write a shellcode on the Linux 390 platform with a complete working example. Here is the URL of the article about the shellcode: http://www.phrack.org/show.php?p=59&a=130
I have tested it and seems to works fine. With such pieces of code also the 390 platform (with Linux on it) can be really open to external attacker (if they get in). Franco Fiorese EDS Italy
