CVE-2021-41495 Open this link in a new tabHow to fix?
Upgrade numpy to version 1.22.2 or higher.
Overview
numpy is a fundamental package needed for scientific computing with Python.
Affected versions of this package are vulnerable to NULL Pointer Dereference due to missing return-value validation in the PyArray_DescrNew function, which may allow attackers to conduct Denial of Service attacks by repetitively creating and sort arrays.
Note: This may likely only happen if application memory is already exhausted, as it requires the newdescr object of the PyArray_DescrNew to evaluate to NULL.
