There is no way to prevent a Windows application running under Wine
from doing everything a Unix application could do. Even if you don't
let CreateProcess launch Unix programs the Windows app can always do a
straight system call. If you want to avoid inadvertently running
/bin/ping you can make sure /bin is not accessible from a DOS
drive. But you can't prevent a malicious app from doing it.
