19 Jan 2021 — 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. Python versiones 3.x hasta 3.9.1, presenta un desbordamiento de búfer en la función PyCArg_repr en el archivo _ctypes/callproc.c, que puede conllevar a una ejecución de código remota en determina... • https://bugs.python.org/issue42938 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
