Josh and Kurt talk about the Time Till Open Source Alternative blog post. The numbers probably don’t mean what we think they mean anymore. A lot of modern open source is really corporate controlled. Just because something carries an open source license doesn’t mean you can contribute to it. https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_341_Time_till_open_source_alternative.mp3 Show Notes Time Till Open Source Alternative GitHub Desktop issue 78 The Reddit Safe

Josh and Kurt talk about containers. There are a lot of opinions around what type of containers is best. Back when it all started there were only huge distro sized containers. Now we have a world with many different container types and sizes. Is one better? https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_326_Big_fat_containers.mp3 Show Notes Programming in the Apocalypse Bob Diachenko Paranoids Podcast

Josh and Kurt talk about a survey about a TuxCare patch management and vulnerability detection. Sometimes our security bubble makes us forget what it’s like in the real world for the people who keep our infrastructure running. Patching isn’t always immediate, automation doesn’t fix everything, and accepting risk is very important. https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_320_Security_Twitter_is_not_the_real_world.mp3 Show Notes State of Enterprise Vulnerability Detection and Patch Management CISA Known Exploited Vulnerabilities Catalog Google 0days

Josh and Kurt talk about the Linux Kernel Dirty Pipe security vulnerability. This bug is an amazing combination of amazing complexity, incredible simplicity, and a little bit of luck. The discovery is amazing, the analysis is enlightening. There’s almost no way a bug like this could be found outside of open source. https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_314_The_Linux_Dirty_Pipe_vulnerability.mp3 Show Notes Dirty Pipe Writeup

Josh and Kurt talk to David A. Wheeler about everything OpenSSF. The Open Source Security Foundation is part of the Linux Foundation, and there are 6 OpenSSF working groups. David does a great job explaining how the OpenSSF works and what the 6 working groups are doing. The working group are (in no particular order): Identifying Security Threats, Security Tooling, Best Practices, Vulnerability Disclosures, Digital Identity Attestation, Securing Critical Projects. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_298_David_A_Wheeler_discusses_the_OpenSSF.mp3 Show Notes David A Wheeler Episode 14 – David A Wheeler: CII Badges Sigstore joins the OpenSSF OpenSSF Technical Working Groups NPM requires MFA LISH Backstabber’s Knife Collection: A Review of Open Source Software Supply Chain Attacks

Josh and Kurt talk about the security of the Matrix movie series. There was a new Matrix trailer that made us want to discuss some of the security themes. We talk about how the movie is very focused on computing in the 90s. How Neo probably ran Linux and they used a real ssh exploit. How a lot of the plot is a bit silly. It’s a really fun episode. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_290_The_security_of_the_Matrix.mp3 Show Notes Matrix 4 trailer nmap in the Matrix VFX Artists react to the Mandalorian Glasshouse Universal Paperclips

Josh and Kurt talk about some happenings in the Linux Kernel. There are some new rules around how to submit patches that goes against how GitHub works. They’re also turning all compiler warnings into errors. It’s really interesting to understand what these steps mean today, and what they could mean in the future. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_288_Linux_Kernel_compiler_warnings_considered_dangerous.mp3 Show Notes The Register Linux story OpenSSL Release Notes

Josh and Kurt talk about the University of Minnesota experimenting on the Linux Kernel. There’s a lot to unpack in this one, but the TL;DR is you probably don’t want to experiment on the kernel. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_269_Do_not_experiment_on_the_Linux_Kernel.mp3 Show Notes Linux Bans University of Minnesota for Sending Buggy Patches in the Name of Research University of Minnesota security researchers apologize for deliberately buggy Linux patches The International Obfuscated C Code Contest

Josh and Kurt talk about attacking open source. How serious is the threat of developers being targeted or a git repo being watched for secret security fixes? The reality of it all is there are many layers in a security journey, the most important things you can do are also the least exciting. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_215_Real_security_is_boring.mp3 Show Notes Targeting developers XKCD Infrastructure comic Hiding security flaws in git Mossad vs Not-Mossad (PDF warning)

Josh and Kurt talk about Secure Boot. The conversation uses the recent “Boot Hole” vulnerability to frame a conversation about what Secure Boot is and isn’t. Why the Boot Hole flaw doesn’t really matter, and why Secure Boot was very scary for Linux users back when it came out. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_209_Secure_Boot_isnt_Secure.mp3 Show Notes Boot Hole
