Overview

opencv-python 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.
