Details

An out-of-bounds read was discovered in OpenCV before 4.1.1. Specifically, variable coarsestscale is assumed to be greater than or equal to finestscale within the calc()/oclcalc() functions in disflow.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.
