Description Dhananjay Arunesh 2019-09-13 13:24:58 UTC 
An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1. There is an out of bounds read in the function cv::predictOrdered<cv::HaarEvaluator> in modules/objdetect/src/cascadedetect.hpp, which leads to denial of service.

Comment 6 Stefan Cornelius 2019-11-19 16:36:09 UTC 
Statement:

It's possible to cause opencv to attempt to read from incorrect or invalid memory when loading specially crafted classifiers (trained data used for object detection), possibly leading to a crash. Although it's technically possible that classifiers are used from untrusted sources, it's  probably an unlikely case in practice.

Since in master we already got 4.1 , I will update F31 with 3.4.7

Fixed in 3.4.10-1 package in f31
