Ubuntu Security Podcast

It's the end of the year for official duties for the Ubuntu Security team so we take a look back on the security highlights of 2024 for Ubuntu and predict what is coming in 2025.

This week we dive into the details of a number of local privilege escalation vulnerablities discovered by Qualys in the needrestart package, covering topics from confused deputies to the inner workings of the /proc filesystem and responsible disclosure as well.

This week we take a deep dive into the latest Linux malware, GoblinRAT to look at how malware is evolving to stay stealthy and evade detection and how malware authors are learning from modern software development along the way.

A recent Microsoft Windows update breaks Linux dual-boot - or does it? This week we look into reports of the recent Windows patch-Tuesday update breaking dual-boot, including a deep-dive into the technical details of Secure Boot, SBAT, grub, shim and more, plus we look at a vulnerability in GNOME Shell and the handling of captive portals as well.
