Vulnerability from github – Published: 2022-05-24 17:34 – Updated: 2024-10-23 18:41
VLAI
Summary
scikit-learn Denial of Service
Details

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.

Severity
7.5 (High)
