CVE-2019-19624 not yet assigned priority: Debian including 1 source packages (opencv), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
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.
