How to fix?

Upgrade Ubuntu:18.04 python2.7 to version 2.7.17-1~18.04ubuntu1.6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python2.7 package and not the python2.7 package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 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.
