CVE-2019-19624 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream opencv package and not the opencv package as distributed by Debian.
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.
