NVD Description

Note: Versions mentioned in the description apply only to the upstream python2-numpy-gnu-hpc-devel package and not the python2-numpy-gnu-hpc-devel package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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
