"According to the versions of the numpy packages installed, the EulerOS Virtualization installation on the remote host is
affected by the following vulnerabilities :

  - Null Pointer Dereference vulnerability exists in numpy.sort in NumPy < 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
