Out-of-bounds Read in OpenCV

An out-of-bounds read was discovered in OpenCV before 4.1.1 OpenCV-Python before 4.1.0.25. 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...

OpenCV calc ocl_calc Buffer Overflow DoS

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...
