New submission from Christian Heimes: Modules/_io/bufferedio.c:_bufferedreader_read_all() doesn't call Py_XDECREF(data) multiple times and may leak a reference in an error case. For example the ref leak occurs when current_size > 0 and PyObject_CallMethodObjArgs(self->raw, _PyIO_str_readall, NULL) fails orbuffered_flush_and_rewind_unlocked(self) fails.
There are a few more places where data isn't decrefed on return, too.
