CVE-2018-7712 : Vulnerability Insights and Analysis

CVE-2018-7712 was published on March 5, 2018, and involves a vulnerability in OpenCV 3.4.1 that can be exploited by remote attackers to cause a denial of service. The issue lies in the validateInputImageSize function in the loadsave.cpp file.

Understanding CVE-2018-7712

This CVE entry highlights a vulnerability in OpenCV 3.4.1 that can lead to a denial of service attack.

What is CVE-2018-7712?

The vulnerability in the validateInputImageSize function of OpenCV 3.4.1 can be exploited by remote attackers to trigger an assertion failure, causing a denial of service. The issue arises when the condition (size.height <= (1<<20)) evaluates to false.

The Impact of CVE-2018-7712

The vulnerability can result in a denial of service by causing an assertion failure in OpenCV 3.4.1. It is crucial to note that the CV_Assert function in OpenCV raises a regular C++ exception, unlike a typical C-like assert().
