EulerOS Virtualization 2.9.1 : numpy (EulerOS-SA-2022-1610)

medium Nessus Plugin ID 170505

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- ** DISPUTED ** 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)

- ** DISPUTED ** 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)

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.

Solution

Update the affected numpy packages.
