Astra Linux – Vulnerability in OpenCV

A out-of-bounds read was discovered in OpenCV prior to version 4.1.1. Specifically, the variable coarsestscale is assumed to be greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp. However, this assumption is incorrect when dealing with small images, resulting in...
