How to fix?

Upgrade Debian:9 python2.7 to version 2.7.13-2+deb9u6 or higher.

NVD Description

Note: Versions mentioned in the description apply to the upstream python2.7 package. See How to fix? for Debian:9 relevant versions.

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.
