An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV 4.1.0

CVE-2019-5063 8.8 - High - January 03, 2020

An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV 4.1.0. A specially crafted XML file can cause a buffer overflow, resulting in multiple heap corruptions and potential code execution. An attacker can provide a specially crafted file to trigger this vulnerability.

An out-of-bounds read was discovered in OpenCV before 4.1.1

CVE-2019-19624 6.5 - Medium - December 06, 2019
