This issue was patched in RHSA-2021:1633.

NVD Description

Note: Versions mentioned in the description apply only to the upstream platform-python-debug package and not the platform-python-debug package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
