Curl vs AI with Daniel Stenberg

Daniel Stenberg, the maintainer of Curl, discusses the increase in AI security reports that are wasting the time of maintainers. We discuss Curl’s new policy of banning the bad actors while establishing some pretty sane AI usage guidelines. We chat about how this low-effort, high-impact abuse pattern is a denial-of-service attack on the curl project (and other open source projects too).

Repository signing with Kairo De Araujo

I recently had a chat with Kairo about a project he maintains called Repository Service for TUF (RSTUF). We explain why TUF is tough (har har har), what RSTUF can do, and some of the challenges around securing repositories. Episode Links Kairo RSTUF TUF RSTUF OpenSSF Slack Channel This episode is also available as a podcast, search for “Open Source Security” on your favorite podcast player. The Update Framework (TUF) Fundamentals TUF has been around for a long time now, starting out as research at New York University. At its core, TUF has a goal of letting clients securely fetch artifacts from package repositories. This sounds simple, or at least not super hard, but it’s actually a really hard problem. TUF provides a framework for signing packages that enables much stronger security guarantees than the traditional approach of curl piped to bash. ...

Securing GitHub Actions with William Woodruff

William Woodruff discussed his project, Zizmor, a security linter designed to help developers identify and fix vulnerabilities within their GitHub Actions workflows. This tool addresses inherent security risks in GitHub Actions, such as injection vulnerabilities, permission issues, and mutable tags, by providing static analysis and remediation guidance. Fresh off the heels of the tj-actions/changed-files backdoor, this is a great topic with some things everyone can do right away.

CVE for EOL with Aaron Frost

Aaron Frost explores the overly complex world of vulnerability identifiers for end of life software. We discuss how incomplete CVE reporting creates blind spots for users while arming attackers with knowledge. The conversation uncovers the ethical tensions between resource constraints and security transparency, highlighting why the “vulnerable until proven otherwise” approach is the best path forward for end of life software.

Distributed CI and Git with Lars Wirzenius

I got to chat with Lars about a new CI/CD system he’s been working on called Ambient. It sounds really cool and does some very clever things today, with even more things planned in the future. We also spend some time discussing a project he works on called Radicle, a distributed Git forge. It feels like having decentralized infrastructure might be more important than it’s ever been, for some reason. ...

FIDO authentication with William Brown

When William Brown posted a rant on Mastodon about the FIDO Metadata Service, it sounded like exactly the sort of thing I wanted to learn more about. So that’s what I did! It’s a fun conversation, William is really good at explaining insanely complicated topics in a way that’s easy to understand.
