Title: Python Buffer Copy without Checking Size of Input (Classic Buffer Overflow) Vulnerability
Overview:

Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c which may lead to remote code execution in certain Python applications that accept floating-point numbers as untrusted input as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used unsafely.
