PSA: When you snap remove something on a stock #ubuntu 24.10, it creates a snapshot of ALL users data for that snap. Make sure you have enough room or use snap remove --purge.

New Ubuntu Linux Security Bypasses require manual Mitigations.
Three security bypasses have been discovered in Ubuntu Linux’s unprivileged user namespace restrictions, which could be enable a local attacker to exploit vulnerabilities in kernel components.
![The three issues allow local unprivileged users to create user namespaces with full administrative capabilities and impact Ubuntu versions 23.10, where unprivileged user namespaces restrictions are enabled, and 24.04 which has them active by default. [Linux user namespaces allow users to act as root inside an isolated sandbox (namespace) without having the same privileges on the host.]
Researchers at cloud security and compliance company Qualys provides technical details for the three bypass methods.
<http://www.qualys.com/2025/three-bypasses-of-Ubuntu-unprivileged-user-namespace-restrictions.txt>
⚠️In a bulletin published on the official discussion forum [Ubuntu Discourse], the company shared the following hardening steps that administrators should consider:⚠️
• Enable kernel.apparmor_restrict_unprivileged_unconfined=1 to block aa-exec abuse. [not enabled by default]
• Disable broad AppArmor profiles for busybox & Nautilus, which allow namespace creation.
• Optionally apply a stricter bwrap AppArmor profile for applications like Nautilus that rely on user namespaces.
• Use aa-status to identify and disable other risky profiles.

Cool!
Als #Ubuntu - Mituserin interessieren mich, welche Kritierien genau ihr wie überprüft.
Veröffentlicht ihr die Ergebnisse hier?
My #Linux laptop "feels" slow. Symptoms are lagging web apps, and sometimes, the whole UI freezes for a second.
Booting from live usb "feels" faster, but it's not an apples-by-apples comparison. The installed system has been updated multiple times and has some apps running in the background, which you don't have on a live system.
I know that this description is not useful. What tests should I do to see what's the cause?
#Ubuntu 24.04 16GB RAM, some Intel CPU and integrated GPU.
Ich hätte nie gedacht, wie hilfreich KI ist ein #ubuntu system zu härten. Es ist, als ob ein erfahrener und geduldiger IT-Experte neben einem sitzt. Wunderbar.
Ich zeige der KI meine Logs und sie gibt richtig gute tipps.
(Und ja, während ich das tue, wandern die Logs nach OpenAI, aber das Risiko ist es mir wert)

As a reminder, here is the not-so-snappy April fool prank of 2 years ago:
It's FOSS News · Enough of it! Ubuntu to Ditch Snap Completely With 24.04 LTS Naughty NightingaleOn this historic date, Canonical has decided to abandon the Snap project and remove it completely in the upcoming release of 24.04 codenamed Naughty Nightingale.
Somebody remembered the April fool news from 2 years ago about Canonical ditching Snap? Here we have a nice new one:
