The vulnerability of the `coarsestscale` variable in the `calc()` and `ocl_calc()` functions of the `dis_flow.cpp` component of the OpenCV library, which is used for computer vision, image processing, and general numerical algorithms. This vulnerability relates to reading data beyond the allowed buffer limits, allowing an attacker to access confidential data and cause service interruptions.

The vulnerability of the coarsestscale parameter in functions calc and oclcalc in the disflow.cpp component of the OpenCV library, which is used for computer vision, image processing, and general numerical algorithms, relates to reading data beyond the allowed buffer size. Exploiting this...

CVE-2019-19624

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 t...
