Descriptions

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.

**EN DISPUTA** La función svm_predict_values en el archivo svm.cpp en Libsvm versión v324, como es usado en scikit-learn versiones 0.23.2 y otros productos, permite a atacantes causar una denegación de servicio (fallo de segmentación) por medio de un modelo SVM diseñado (introducido por medio de pickle, json o cualquier otro modelo estándar de permanencia) con un valor grande en la matriz _n_supportNOTA: la posición del proveedor de scikit-learn es que el comportamiento sólo puede ocurrir si la API de la biblioteca es violada por una aplicación que cambia un atributo privado

A vulnerability was found in scikit-learn which could result in denial of service. Versions less than 1.1.1 are affected.
