An out-of-bounds read was discovered in OpenCV before 4.1.1.

Does this matter?

Lower severity and a low EPSS score (1.76%). Track it; it rarely justifies an emergency change on its own.

Description

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.
