Integer Overflow in F Prime Framework Causes DoS

Executive Summary

This vulnerability is an integer overflow in the Svc::FileDownlink::SendPartial component of the fprime framework version 4.2.2. An integer overflow occurs when a calculation exceeds the maximum value an integer can hold, causing unexpected behavior. In this case, it can lead to a Denial of Service (DoS) where the system becomes unresponsive or crashes when processing specially crafted input.
