It happened before any application code ran, and it affected every PHP version back to 5.4. Volker Dusch, PHP 8.5 release manager and AI Security Engineer in Residence at the PHP Foundation, worked with the PHP security team on the fix. He takes us from an urgent email with a working exploit in a Docker container to a release day that went anything but according to plan. How did researchers find a bug that had been hiding in PHP’s out-of-memory handling for more than a decade? Why does fixing it mean hunting down every single place the pattern occurs, and why does a fix in php-src take so long to reach your server? And what happens when CVE IDs leak early, an exploit video goes online by accident, and patched images ship hours before the embargo lifts? Don't miss this insightful talk, engaging discussions, and networking opportunities. We can't wait to see you all at the Symfony User Group of November. If you have any questions or accessibility requirements, please reach out to us.
