"According to the versions of the numpy packages installed, the EulerOS Virtualization installation on the remote host is
affected by the following vulnerabilities :
- Buffer overflow in the array_from_pyobj function of fortranobject.c in NumPy < 1.19, which allows
attackers to conduct a Denial of Service attacks by carefully constructing an array with negative values.
NOTE: The vendor does not agree this is a vulnerability; the negative dimensions can only be created by an
already privileged user (or internally) (CVE-2021-41496)
