The vulnerability of the `coarsestscale` variable in the `calc()` and `ocl_calc()` functions of the `dis_flow.cpp` component of the OpenCV library, which is used for computer vision, image processing, and general numerical algorithms. This vulnerability relates to reading data beyond the allowed buffer limits, allowing an attacker to access confidential data and cause service interruptions.

The vulnerability of the coarsestscale parameter in functions calc and oclcalc in the disflow.cpp component of the OpenCV library, which is used for computer vision, image processing, and general numerical algorithms, relates to reading data beyond the allowed buffer size. Exploiting this...

GHSA-JGGW-2Q6G-C3M6 Out-of-bounds Read in OpenCV

An out-of-bounds read was discovered in OpenCV before 4.1.1 OpenCV-Python before 4.1.0.25. Specifically, variable coarsestscale is assumed to be greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp. However, this is not true when dealing with small images, leading...

Denial Of Service (DoS)

OpenCV is vulnerable to denial of service DoS. The attack exists when a small image is input, triggering an out-of-bounds read via segmentation fault as the variable coarsestscale is no longer greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp...

CVE-2019-19624

An out-of-bounds read was discovered in OpenCV before 4.1.1. Specifically, variable coarsestscale is assumed to be greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp. However, this is not true when dealing with small images, leading to an out-of-bounds read of t...

CVE-2019-16249

OpenCV 4.1.1 has an out-of-bounds read in halbaseline::vload in core/hal/intrinsse.hpp when called from computeSSDMeanNorm in modules/video/src/disflow.cpp...
