GHSA-hc96-xw56-vfwh PUBLISHED CVSS 9.800000190734863 CRITICAL

Record from GitHub Advisory Database · Published May 24, 2022

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.
