Join us for a conversation with Foxboron (Morten Linderud) and Anthraxx (Levente Polyak), members of the Arch Linux security team. We talk about the difficulties of maintaining a Linux distribution, the challenges of handling CVEs, and the dedication of volunteers who keep the open-source community working (and how overworked those volunteers are). We explain what makes Arch a little different, how they approach their security process, and what sort of help they would love to see in the future.

In this episode I chat with the authors of a recent paper on open source security: Open Source, Open Threats? Investigating Security Challenges in Open-Source Software. I chat with Ali Akhavani and Behzad Ousat about their findings. There are interesting data points in the paper such as a 98% increase in reported vulnerabilities compared to a 25% growth in open source ecosystems. We discuss the challenges of maintaining security in a rapidly expanding digital landscape, and learn about the role of community engagement and automated tools in addressing these discrepancies. It's a great paper and a fantastic discussion.

In this episode I chat with Patrick Garrity from VulnCheck. We discuss the chaos that has enveloped the CVE and NVD programs over the past two years. We cover some of the transparency and communication challenges with the existing program. What some of the new things that have started to emerge as well as why they seem to be struggling. We end on the note that the last 3 months haven't been confidence inspiring. It's likely in 6 months everyone will be scrambling to deal with a difficult situation.

In this episode I discuss GCVE and Vulnerability-Lookup with Alex and Cedric from CIRCL. GCVE offers a decentralized approach, allowing organizations to assign their own IDs and publish vulnerabilities independently. Vulnerability-Lookup is the tool that makes GCVE a reality. The flexibility addresses many of the limitations we see today with a single centralized ID system. The work happening by CIRCL on GCVE is very impressive, with all the current CVE turmoil, this is a project we should all be paying attention to.
