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.");
