GLSA-202301-03 : scikit-learn: Denial of Service

high Nessus Plugin ID 169836


The remote host is affected by the vulnerability described in GLSA-202301-03 (scikit-learn: Denial of Service)

- ** 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. (CVE-2020-28975)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


All scikit-learn users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=sci-libs/scikit-learn-1.1.1
