Descriptions
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.
Se detectó una lectura fuera de límites en OpenCV versiones anteriores a 4.1.1. Específicamente, una variable coarsest_scale es asumida para ser mayor o igual que finest_scale dentro de las funciones calc() y ocl_calc() en el archivo dis_flow.cpp. Sin embargo, esto no es cierto cuando se trata de imágenes pequeñas, conllevando a una lectura fuera de límites de las matrices Ux y Uy asignadas de la pila.
