Python 3.6 (June 27, 2020) (https://www.python.org/ftp/python/3.6.11/Python-3.6.11.tgz). I found an exploitable segmentation fault in Python 3.6.11 (I validated that by using GDB's Exploitable plugin). Please find the attachment. #0 0x0000000000b63bf4 in _PyEval_EvalFrameDefault (f=<optimized out>, throwflag=<optimized out>) at Python/ceval.c:3667 #1 0x0000000000b5bc5b in PyEval_EvalFrameEx (throwflag=0, f=0x7ffff7f66c50) at Python/ceval.c:754 #2 _PyEval_EvalCodeWithName (_co=_co@entry=0x7ffff7ef5030, globals=globals@entry=0x7ffff7f62168, locals=locals@entry=0x7ffff7f62168, args=args@entry=0x0, argcount=argcount@entry=0, kwnames=kwnames@entry=0x0, kwargs=0x0, kwcount=0, kwstep=2, defs=0x0, defcount=0, kwdefs=0x0, closure=0x0, name=0x0, qualname=0x0) at Python/ceval.c:4166 #3 0x0000000000b6100b in PyEval_EvalCodeEx (closure=0x0, kwdefs=0x0, defcount=0, defs=0x0, kwcount=0, kws=0x0, argcount=0, args=0x0, locals=locals@entry=0x7ffff7f62168, globals=globals@entry=0x7ffff7f62168, _co=_co@entry=0x7ffff7ef5030) at Python/ceval.c:4187 #4 PyEval_EvalCode (co=co@entry=0x7ffff7ef5030, globals=globals@entry=0x7ffff7f62168, locals=locals@entry=0x7ffff7f62168) at Python/ceval.c:731 ---------- files: ExploitableCrash.pyc messages: 372776 nosy: Iman Sharafodin priority: normal severity: normal status: open title: An exploitable segmentation fault in _PyEval_EvalFrameDefault versions: Python 3.6 Added file: https://bugs.python.org/file49285/ExploitableCrash.pyc _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41189> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
