Echo: numpy: security update to 1.22.2

medium Tenable Self-Hosted Container Security Plugin ID 455281

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Null Pointer Dereference vulnerability exists in numpy.sort in NumPy &lt and 1.19 in the PyArray_DescrNew
 function due to missing return-value validation, which allows attackers to conduct DoS attacks by
 repetitively creating sort arrays. NOTE: While correct that validation is missing, an error can only occur
 due to an exhaustion of memory. If the user can exhaust memory, they are already privileged. Further, it
 should be practically impossible to construct an attack which can target the memory exhaustion to occur at
 exactly this place (CVE-2021-41495)

Solution

Update the numpy library and its related packages to version 1.22.2 or later.
