CVE-2019-14492

An out-of-bounds read flaw was found in OpenCV in the way the Cascade Classifier algorithm loaded and processed the Haar feature-based cascade classifiers. This flaw allows a remote attacker to provide a specially crafted classifier in the form of an XML file that, when loaded by an application linked to OpenCV, would crash the application, causing a denial of service.

Mitigation

Avoid loading cascade classifiers from external untrusted sources.
