## Summary
MES PCs shipped with Windows 10 come pre-installed with XAMPP. XAMPP is a bundle of third-party open-source applications including the Apache HTTP Server, the MariaDB database and more. From time to time, vulnerabilities in these applications are discovered. These are fixed in newer versions of XAMPP by updating the bundled applications. MES PCs shipped with Windows 10 include a copy of XAMPP which contains around 140 such vulnerabilities listed in this advisory. They can be fixed by replacing XAMPP with Festo Didactic's Factory Control Panel application.

A Comparative Study of Fuzzers and Static Analysis Tools for Finding Memory Unsafety in C and C++
## Abstract
Even today, over 70% of security vulnerabilities in critical software systems result from memory safety violations.
To address this challenge, fuzzing and static analysis are widely used automated methods to discover such vulnerabilities.
Fuzzing generates random program inputs to identify faults, while static analysis examines source code to detect potential vulnerabilities.
Although these techniques share a common goal, they take fundamentally different approaches and have evolved largely independently.
In this paper, we present an empirical analysis of static analyzers and fuzzers, applied to over 100 known security vulnerabilities in C/C++ programs.
We measure the number of
