New submission from Armin Rigo <ar...@users.sourceforge.net>: The __str__ method of some exception classes reads attributes without typechecking them. Alternatively, the issue could be that the user is allowed to set the value of these attributes directly, without typecheck. The typechecking is only done when we create the exception, but not later. Example:
>>> u=UnicodeTranslateError(u'x', 1, 5, 'bah') >>> u.reason = 0x345345345345345345 >>> str(u) "can't translate characters in position 1-4: E\x03" The 'E\x03' comes from PyString_AS_STRING(reason). By playing enough it is probably possible to come up with a real crasher. ---------- components: Interpreter Core messages: 95159 nosy: arigo severity: normal status: open title: crasher in str(Exception()) versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7309> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
