Description
The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.
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.
Mitigation
Install update from vendor's website.
Vulnerable software versions
OpenCV: 4.1.0
