NumPy < 1.22.2 Null Pointer Dereference

medium Nessus Plugin ID 210057

Synopsis

The remote host is affected by a vulnerability.

Description

The version of NumPy installed on the remote host is prior to 1.22.2. It is, therefore, affected by a Null Pointer Dereference vulnerability exists in numpy.sort in NumPy prior to 1.22.2 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

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

Solution

Upgrade to NumPy version 1.22.2 or later.
