Out-of-bounds Read in OpenCV
🔗 CVE IDs covered (1)
📋 Description
An out-of-bounds read was discovered in OpenCV before 4.1.1 (OpenCV-Python before 4.1.0.25). 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.
🎯 Affected products4

- pip/opencv-python-headless:<= 4.1.0.24
- pip/opencv-contrib-python:<= 4.1.0.24
