CVE-2019-19624

6.5 mediumEPSS 1.8%

Medium (6.5). EPSS 1.8% chance of exploitation in the next 30 days. Fixed in opencv-python 4.1.0.25.

An out-of-bounds read was discovered in OpenCV before 4.1.1. Specifically, variable coarsest_scale is assumed to be greater than or equal to finest_scale within the calc()/ocl_calc() functions in dis_flow.cpp. However, this is not true when dealing with small images, leading to an out-of-bounds read of the heap-allocated arrays Ux and Uy.
