CVE-2019-5064

31
FAUCET Score

CVE-2019-5064 is a high-severity heap buffer overflow vulnerability in the data structure persistence functionality of OpenCV, affecting versions prior to 4.2.0, as well as several Oracle products that integrate OpenCV. A specially crafted JSON file can trigger this vulnerability, leading to multiple heap corruptions and potential remote code execution. With a CVSS score of 8.8, it presents a significant risk due to its network-based attack vector and low attack complexity, requiring user interaction. While there is no known active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), it has garnered some community discussion and media coverage, indicating awareness of its potential impact.
