What is CVE-2018-7714?

The validateInputImageSize function in the OpenCV image processing library version 3.4.1 is vulnerable to a denial of service attack. This vulnerability allows remote attackers to trigger an assertion failure through improper input parameters, specifically when the condition 'pixels <= (1<<30)' evaluates to false. The issue arises from the fact that the CV_Assert in OpenCV is a regular C++ exception rather than a traditional C-style assert, making it susceptible to assertion failures in cases of invalid or unsupported parameter values.
