| Description: | An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1. There is an out of bounds read/write in the function HaarEvaluator::OptFeature::calc in modules/objdetect/src/cascadedetect.hpp, which leads to denial of service. It was discovered that OpenCV incorrectly handled certain files. An attaacker could possibly use this issue to cause a denial of service.
