Improving Software Security in Open Source Dependencies

Open source software has become an integral part of many software development projects, but it often comes with security vulnerabilities. In fact, a recent report by Synopsys found that 74% of commercial codebases contain open source components affected by high-risk vulnerabilities. This poses a significant challenge for developers who rely on these libraries or components.

To address this challenge, a team of researchers at North Carolina State University has developed VFCFinder, a tool that streamlines the process of analyzing open source software updates. VFCFinder allows programmers to identify the specific code changes that address security vulnerabilities, improving the security of software supply chains.

Traditionally, developers faced a difficult decision when it came to updating their dependencies. Updating to the fixed version would address the vulnerability, but it could also introduce unexpected changes that could break the project. To make an informed decision, developers needed more information about whether the vulnerable part of the old version was actually used.

VFCFinder provides this information by analyzing commit histories and pinpointing the most likely commits associated with vulnerability fixes. This streamlines the decision-making process for developers, allowing them to ensure application security without compromising working code.

The researchers envision VFCFinder being used by software supply chain security firms and project maintainers to enrich vulnerability data and automate the process of identifying and addressing vulnerabilities. By providing a ranked list of potential software commits that correspond to a security advisory, VFCFinder significantly reduces the manual effort required to identify vulnerability fixing commits.

In an effort to promote transparency and collaboration, the researchers have made VFCFinder and its machine learning models open source. They encourage software supply chain security firms and maintainers of vulnerability databases to use VFCFinder and contribute their findings back into open databases. This collaborative approach will ultimately lead to the development of better tools to assist developers and project maintainers in dealing with vulnerabilities in open source software dependencies.

By leveraging VFCFinder and embracing a collective effort, we can improve the security of open source software and ensure that developers have the necessary tools to protect their projects from potential vulnerabilities.
