Background
OpenCV is an open-source computer vision and machine learning software library. It provides a wide range of functions and algorithms for image and video processing, object detection, and more. OpenCV version 3.3 and earlier are affected by multiple vulnerabilities, including out-of-bounds read/write errors, buffer overflows, and double free issues.
Vulnerability Detail
The vulnerabilities in OpenCV can be exploited by an attacker to read or write data outside the bounds of allocated memory, leading to potential information disclosure or arbitrary code execution. These vulnerabilities may be triggered by processing specially crafted image or video files. The impact of these vulnerabilities can vary depending on the context in which OpenCV is used, but they have the potential to compromise the integrity and confidentiality of the system.
