Dissecting Code Vulnerabilities: Insights from C++ and Java Vulnerability Analysis with ReVeal Model
share
This study presents an analysis conducted on a real-world dataset of Java vulnerability-fixing commits. The dataset consists of commits with varying numbers of modified methods, leading to a natural partitioning based on the number of changed functions. The research aims to address several key questions. Firstly, the study investigates the optimal parameter selection for ReVeal, a state-of-the-art model, in order to achieve its best performance. Secondly, it explores the contributions of different parts of the Java dataset towards vulnerability detection. Lastly, the study evaluates the model's performance in separating close-to-vulnerable methods (vulnerable methods and their fixed versions) from randomly selected safe code, as well as the finer separation of vulnerable methods from their fixed versions within the set of close-to-vulnerable methods. The research employs a series of experiments to answer these questions and derive meaningful insights.
