An issue was discovered in OpenCV before 4.1.1. There is a NULL pointer dereference in the function cv::XMLParser::parse at modules/core/src/persistence.cpp.
A NULL pointer dereference flaw was found in OpenCV in the way the Cascade Classifier algorithm loaded and processed certain classifiers. A remote attacker could exploit this flaw by providing a specially crafted XML file that, when loaded by an application linked to OpenCV, would crash the application causing a denial of service.
Statement: This flaw did not affect the versions of OpenCV as shipped with Red Hat Enterprise Linux 6, 7, and 8 as they did not include the vulnerable code, which was introduced in a newer version of

## Abstract
Machine learning is a field of artificial intelligence (AI) that is becoming essential for several critical systems, making it a good target for threat actors. Threat actors exploit different Tactics, Techniques, and Procedures (TTPs) against the confidentiality, integrity, and availability of Machine Learning (ML) systems.
During the ML
cycle, they exploit adversarial TTPs to poison data and fool ML-based systems. In recent years, multiple security practices have been proposed for traditional systems but they are not enough to cope with th
