SUSE SLES12 Security Update : python-numpy (SUSE-SU-2022:2645-1)

medium Nessus Plugin ID 163825

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2022:2645-1 advisory.

 - ** 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)

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

Solution

Update the affected python-numpy and / or python-numpy-devel packages.
