Serhiy Storchaka added the comment: One funny thing is that the same data can produce different result when unpickled with pickle and cPickle in 2.x. But unlikely it is larger vulnerability than using unpickling at all.
Just FYI: PyPy 2.2.1: >>>> import pickle, cPickle >>>> pickle.loads(b'I010\n.') 10 >>>> cPickle.loads(b'I010\n.') 10 >>>> pickle.loads(b'L010\n.') 8L >>>> cPickle.loads(b'L010\n.') 8L Jython 2.5.3: >>> import pickle, cPickle >>> pickle.loads('I010\n.') 10 >>> cPickle.loads('I010\n.') 10 >>> pickle.loads('L010L\n.') 8L >>> cPickle.loads('L010L\n.') 10L ---------- resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25248> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
