Destination Linux 489: PHP2Shell Emergency & Inside the OOSC Conference

In Destination Linux Episode 489, Ryan and Jill deliver a tight, focused episode centered around community perspectives, major security news, and an inspiring interview with the organizers of India’s rapidly growing Opportunity Open Source Conference (OOSC).

We begin with community feedback on AI art, exploring how prompting, creativity, and human intention intersect in this evolving medium.

Then we dive into the PHP2Shell emergency: two critical vulnerabilities (CVE‑2026‑109618 and CVE‑2026‑109619) affecting PHP’s session.upload_progress feature. These flaws allow unauthenticated remote code execution and forced an emergency patch release. We break down what happened, who’s affected, and what everyday users, site owners, and administrators need to do right now.

In our feature interview, we welcome Akarshan and Till Kamppeter from OOSC, founded by OpenPrinting’s Till Kamppeter and Aveek Basu. OOSC 4.0 brought together more than 500 developers, researchers, and students, and the team used Destination Linux as a framework for their streaming and event structure. We talk inspiration, challenges, community impact, and the future of OOSC.

Plus new patrons, merch shoutouts, and plenty of laughs along the way.

Boot up your favorite distro, fire up your terminal, and join us for another Linux adventure.
