CVE-2020-28975

DISPUTED svm_predict_values in svm.cpp in Libsvm v324, as used in
scikit-learn 0.23.2 and other products, allows attackers to cause a denial
of service (segmentation fault) via a crafted model SVM (introduced via
pickle, json, or any other model permanence standard) with a large value in
the _n_support array. NOTE: the scikit-learn vendor’s position is that the
behavior can only occur if the library’s API is violated by an application
that changes a private attribute.
