Summary
Python is prone to a buffer overflow vulnerability in 'PyCArg_repr'.
Insight
Insight
A buffer overflow in 'PyCArg_repr' in '_ctypes/callproc.c' exists, 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.
