Vulnerability description
DayBreach CVE AI Research
CVE-2021-3177 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
