Vulnerability Spotlight: Two buffer overflow vulnerabilities in OpenCV
Summary: Cisco Talos discovered two heap buffer overflow vulnerabilities in OpenCV 4.1.0, one in its XML data structure persistence functionality and one in its JSON persistence parser, tracked as TALOS-2019-0853/CVE-2019-5064. A specially crafted XML or JSON file can trigger the overflow, causing multiple heap corruptions and potentially code execution.
Bottom line: OpenCV runs in facial recognition, robotics, motion tracking and machine learning systems, so a file that triggers code execution in those libraries reaches beyond a single application. Talos worked with OpenCV.org on a fix and published Snort rules 50774 and 50775, which means detection depends on whether those signatures are actually deployed.
