Multiple, serious security vulnerabilities found in the Rust clone of Sudo — which shipped with Ubuntu 25.10 (the most recent release). Not little vulnerabilities: We’re talking about the disclosure of passwords and total bypassing of authentication. In fact, we’re getting new…

The Intune MDM Device Certificate and its renewal… Next year (around 03/04 of 2026) every single Intune MDM certificate will need renewal. Yes, all of them!!!!!!! Why? Because the Microsoft Intune Root Certification Authority is expiring. I’m marking that date in my calendar,…
