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

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

  - 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)

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 1.21.0. It is, therefore, affected by 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

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)

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.
