An incomplete string comparison in the numpy.core component in NumPy before 1.22.0 allows attackers to trigger slightly incorrect copying by constructing specific string objects. NOTE: the vendor states that this reported code behavior is "completely harmless."

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-016631 advisory.

    An incomplete string comparison in the numpy.core component in NumPy before 1.22.0 allows attackers to     trigger slightly incorrect copying by constructing specific string objects. NOTE: the vendor states that     this reported code behavior is completely harmless.

Tenable has extracted the preceding description block directly from the Unity 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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An incomplete string comparison in the numpy.core component in NumPy before 1.22.0 allows attackers to     trigger slightly incorrect copying by constructing specific string objects. NOTE: the vendor states that     this reported code behavior is completely harmless. (CVE-2021-34141)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of NumPy installed on the remote host is prior to 1.22.0. It is, therefore, affected by an incomplete string comparison vulnerability in the numpy.core component in NumPy before 1.22.0 allows attackers to trigger slightly incorrect copying by constructing specific string objects. NOTE: the vendor states that this reported code behavior is completely harmless.

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

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5763-1 advisory.

    It was discovered that NumPy did not properly manage memory when specifying arrays of large dimensions. If     a user were tricked into running malicious Python file, an attacker could cause a denial of service. This     issue only affected Ubuntu 20.04 LTS. (CVE-2021-33430)

    It was discovered that NumPy did not properly perform string comparison operations under certain     circumstances. An attacker could possibly use this issue to cause NumPy to crash, resulting in a denial of     service. (CVE-2021-34141)

    It was discovered that NumPy did not properly manage memory under certain circumstances. An attacker could     possibly use this issue to cause NumPy to crash, resulting in a denial of service. (CVE-2021-41495,     CVE-2021-41496)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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