[issue32583] Crash during decoding using UTF-16/32 and custom error handler
New submission from Alexander Sibiryakov <sixty-...@yandex.ru>: The CPython interpreter gets SIGSEGV or SIGABRT during the run. The script attempts to decode binary file using UTF-16-LE encoding and custom error handler. The error handler is poorly built, and doesn't respect the unicode standard with wrong calculation of the new position for decoder to continue. This somehow interfere with internal C code doing memory allocation. The result is invalid writes outside of allocated block. Here is how it looks like with Python 3.7.0a4+ (heads/master:44a70e9, Jan 17 2018, 12:18:45) run under Valgrind 3.11.0. Please see the full Valgrind output in attached valgrind.log. ==24836== Invalid write of size 4 ==24836==at 0x4C6B17: ucs4lib_utf16_decode (codecs.h:540) ==24836==by 0x4C6B17: PyUnicode_DecodeUTF16Stateful (unicodeobject.c:5600) ==24836==by 0x55AAD3: _codecs_utf_16_le_decode_impl (_codecsmodule.c:363) ==24836==by 0x55AB6C: _codecs_utf_16_le_decode (_codecsmodule.c.h:371) ==24836==by 0x4315D6: _PyMethodDef_RawFastCallKeywords (call.c:651) ==24836==by 0x431840: _PyCFunction_FastCallKeywords (call.c:730) ==24836==by 0x4ED159: call_function (ceval.c:4580) ==24836==by 0x4ED159: _PyEval_EvalFrameDefault (ceval.c:3134) ==24836==by 0x4E302D: PyEval_EvalFrameEx (ceval.c:545) ==24836==by 0x4E3A42: _PyEval_EvalCodeWithName (ceval.c:3971) ==24836==by 0x430EDD: _PyFunction_FastCallDict (call.c:376) ==24836==by 0x4336B0: PyObject_Call (call.c:226) ==24836==by 0x433839: PyEval_CallObjectWithKeywords (call.c:826) ==24836==by 0x4FEAA6: _PyCodec_DecodeInternal (codecs.c:471) ==24836== Address 0x6cf4bf8 is 0 bytes after a block of size 339,112 alloc'd ==24836==at 0x4C2DB8F: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==24836==by 0x467635: _PyMem_RawMalloc (obmalloc.c:75) ==24836==by 0x467B7D: _PyMem_DebugRawAlloc (obmalloc.c:2033) ==24836==by 0x467C1F: _PyMem_DebugRawMalloc (obmalloc.c:2062) ==24836==by 0x467C40: _PyMem_DebugMalloc (obmalloc.c:2202) ==24836==by 0x468BFF: PyObject_Malloc (obmalloc.c:616) ==24836==by 0x493902: PyUnicode_New (unicodeobject.c:1293) ==24836==by 0x4BEA4F: _PyUnicodeWriter_PrepareInternal (unicodeobject.c:13456) ==24836==by 0x4C6D39: _PyUnicodeWriter_WriteCharInline (unicodeobject.c:13494) ==24836==by 0x4C6D39: PyUnicode_DecodeUTF16Stateful (unicodeobject.c:5637) ==24836==by 0x55AAD3: _codecs_utf_16_le_decode_impl (_codecsmodule.c:363) ==24836==by 0x55AB6C: _codecs_utf_16_le_decode (_codecsmodule.c.h:371) ==24836==by 0x4315D6: _PyMethodDef_RawFastCallKeywords (call.c:651) -- Added file: https://bugs.python.org/file47393/valgrind.log ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32583> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
