NumPy has an unspecified vulnerability

NumPy is a Python scientific computing package. The product supports a large number of dimensional arrays and matrices, while providing a large library of mathematical functions for data operations. numPy 1.19 has a security vulnerability that stems from a null pointer dereference vulnerability in numpy. In the software PyArray_DescrNew function, the lack of return value validation leads to a null pointer dereference vulnerability, which can be exploited by attackers to conduct DoS attacks by repeatedly creating sorted arrays.
