The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2022:8852 advisory.

    A fast multidimensional array facility for Python

    Security Fix(es):

    * NULL pointer dereference in numpy.sort in the PyArray_DescrNew() due     to missing return-value validation (CVE-2021-41495)

    For more details about the security issue(s), including the impact, a CVSS     score, acknowledgments, and other related information, refer to the CVE     page listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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.

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)

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2441-1 advisory.

  - ** DISPUTED ** A Buffer Overflow vulnerability exists in NumPy 1.9.x in the PyArray_NewFromDescr_int     function of ctors.c when specifying arrays of large dimensions (over 32) from Python code, which could let     a malicious user cause a Denial of Service. NOTE: The vendor does not agree this is a vulneraility; In     (very limited) circumstances a user may be able provoke the buffer overflow, the user is most likely     already privileged to at least provoke denial of service by exhausting memory. Triggering this further     requires the use of uncommon API (complicated structured dtypes), which is very unlikely to be available     to an unprivileged user. (CVE-2021-33430)
