Yes, assuming that you are loading the kernel from a directory that can be accessed without privileges. Generally the Python distribution is stored in a pseudo-readonly directory without privileges. UAC on Windows, for example. That is different with reading input files - generally files like that are stored somewhere under the user folder and as such can be accessed easily. Someone could craft an input file that when opened did pretty much anything. If this is a problem for formats like PDF (and it is), why would one not consider this a problem in this case?
