CVE-2020-28975
HIGH7.5EPSS 0.25%scikit-learn Denial of Service
Published: 5/24/2022Modified: 12/3/2024
Description
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.
Affected packages (2)
- PyPI/scikit-learn>= 0.23.2, < 1.0.1
- PyPI/scikit-learnfrom 0, < 0.24.dev0
