How to fix?

Upgrade opencv-python-headless to version 4.1.0.25 or higher.

Overview

opencv-python-headless is a Wrapper package for OpenCV python bindings.

Affected versions of this package are vulnerable to Out-of-bounds Read. The coarsest_scale variable 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.
