Microsoft Open Sources Windows Subsystem for Linux
by Peter Reutemann 20 May '25

20 May '25

'Windows Subsystem for Linux (WSL) is now open source, Microsoft said Monday. The tool, which allows developers to run Linux distributions directly in Windows, is available for download, modification, and contribution. "We want Windows to be a great dev box," said Pavan Davuluri, corporate VP at Microsoft. "Having great WSL performance and capabilities" allows developers "to live in the Windows-native experience and take advantage of all they need in Linux." First launched in 2016 with an emulated Linux kernel, WSL switched to using the actual Linux kernel in 2019 with WSL 2, improving compatibility. The system has since gained support for GPUs, graphical applications, and systemd. Microsoft significantly refactored core Windows components to make WSL a standalone system before open sourcing it.' -- source: https://news.slashdot.org/story/25/05/19/1654225 Cheers, Peter

20 May '25

'The Raspberry Pi Foundation has just released a new version of Raspberry Pi OS, their recommended, freely distributed operating system for all Raspberry Pi devices. Still based on Debian 12 ”Bookworm,” this build is likely the last one in this series before Debian 13 “Trixie” arrives later this summer.' -- source: https://linuxiac.com/final-bookworm-based-raspberry-pi-os-released-ahead-of… Cheers, Peter

Raspberry Pi Connect Goes Stable
by Peter Reutemann 19 May '25

19 May '25

'After just twelve months of public testing, Raspberry Pi Connect—the company’s browser-based remote-access service—officially graduated from beta with the release of version 2.5. According to Raspberry Pi engineer Chris Lowder, the platform’s install base has already topped 100,000 registered boards. Earlier iterations of the software relied on frequent polling: each Pi woke up at regular intervals to ask Raspberry Pi’s servers whether anyone wanted to connect. That design was easy on the cloud side—traffic remained predictable—but it quietly chewed through users’ data plans and power budgets. Version 2.5 replaces that pattern with a single, persistent HTTP connection. Now, when a user presses “Connect” in the web dashboard, the server broadcasts a wake-up event to the board, initiating the handshake on demand instead of on a schedule. Beyond wake-ups, every Connect client has been sending status heartbeats to keep the dashboard in sync. The new release debounces that chatter, dropping superfluous packets and compressing each remaining heartbeat by roughly 50 percent.' -- source: https://linuxiac.com/raspberry-pi-connect-goes-stable/ Anyone got any experience with this that they'd like to share?

Spies hack high-value mail servers using an exploit from yesteryear
by Peter Reutemann 16 May '25

16 May '25

'Threat actors, likely supported by the Russian government, hacked multiple high-value mail servers around the world by exploiting XSS vulnerabilities, a class of bug that was among the most commonly exploited in decades past. XSS is short for cross-site scripting. Vulnerabilities result from programming errors found in webserver software that, when exploited, allow attackers to execute malicious code in the browsers of people visiting an affected website. XSS first got attention in 2005, with the creation of the Samy Worm, which knocked MySpace out of commission when it added more than one million MySpace friends to a user named Samy. XSS exploits abounded for the next decade and have gradually fizzled more recently, although this class of attacks continues now. On Thursday, security firm ESET reported that Sednit, a Kremlin-backed hacking group also tracked as APT28, Fancy Bear, Forest Blizzard, and Sofacy—gained access to high-value email accounts by exploiting XSS vulnerabilities in mail server software from four different makers. Those packages are: Roundcube, MDaemon, Horde, and Zimbra.' -- source: https://arstechnica.com/security/2025/05/spies-hack-high-value-mail-servers… Cheers, Peter

Google Restores File Permissions For Nexcloud
by Peter Reutemann 16 May '25

16 May '25

'Nextcloud has been in an ongoing battle with Google over the tech giant revoking the All Files permission from the Nextcloud Android App, which prevents users from managing their files on their server. After a blog post and several tech sites reported on the issue, "Google reached out to us [Nexcloud] and offered to restore the permission, which will give users back the functionality that was lost." Nextcloud is working on an app update and hopes to have it pushed out within a week.' -- source: https://tech.slashdot.org/story/25/05/15/208221 Cheers, Peter

You Can Now Upgrade Ubuntu 24.10 to Ubuntu 25.04, Here’s How
by Peter Reutemann 15 May '25

15 May '25

'After almost a month of waiting, Ubuntu 24.10 (Oracular Oriole) users can finally upgrade their installations to the latest Ubuntu 25.04 (Plucky Puffin) release. Here’s a step-by-step tutorial with screenshots on how to perform the upgrade! Ubuntu 24.10 was released on October 10th, 2024, and will be supported for a couple more months, until July 2025. Since this isn’t an LTS (Long Term Support) release, users might want to consider upgrading to Ubuntu 25.04 as soon as possible. Compared to Ubuntu 24.10, the Ubuntu 25.04 release ships with a newer kernel for better hardware support, namely Linux 6.14, the Mesa 25 graphics stack series for a better gaming experience, the latest GNOME 48 desktop environment, as well as some of the most recent GNU/Linux technologies.' -- source: https://9to5linux.com/you-can-now-upgrade-ubuntu-24-10-to-ubuntu-25-04-here… Cheers, Peter

Introducing oniux: Kernel-level Tor isolation for any Linux app
by Peter Reutemann 15 May '25

15 May '25

'When launching privacy-critical apps and services, developers want to make sure that every packet really only goes through Tor. One mistyped proxy setting–or a single system-call outside the SOCKS wrapper–and your data is suddenly on the line. That's why today, we are excited to introduce oniux: a small command-line utility providing Tor network isolation for third-party applications using Linux namespaces. Built on Arti, and onionmasq, oniux drop-ships any Linux program into its own network namespace to route it through Tor and strips away the potential for data leaks. If your work, activism, or research demands rock-solid traffic isolation, oniux delivers it.' -- source: https://blog.torproject.org/introducing-oniux-tor-isolation-using-linux-nam… Cheers, Peter

Multiple Security Issues in Screen (mostly affecting release 5.0.0 and setuid-root installations)
by Peter Reutemann 14 May '25

14 May '25

'In July 2024, the upstream Screen maintainer asked us [2] if we could have a look at the current Screen code base. We treated this request with lower priority, since we already had a cursory look at Screen a few years earlier, without finding any problems. When we actually found time to look into it again, we were surprised to find a local root exploit in the Screen 5.0.0 major version update affecting distributions that ship it as setuid-root (Arch Linux and NetBSD). We also found a number of additional, less severe issues that partly also affect older Screen versions still found in the majority of distributions.' -- source: https://www.openwall.com/lists/oss-security/2025/05/12/1 Cheers, Peter

FreeBSD Wants to Know a Few Things
by Peter Reutemann 14 May '25

14 May '25

'The FreeBSD Core Team and the FreeBSD Foundation have a few questions it would like to ask its users. What this means is that it’s survey time at FreeBSD… again. In other words, 2024’s user survey turns out not to have been the one-off we thought it was, and the FreeBSD Community Survey is looking like it’s going to become an annual event. This year’s survey was announced on Friday will run through May 7. Taking it won’t take much time — 15 minutes the organization says on its website — and the information gleaned from the results will be key for keeping the project on track. The foundation says that last year’s survey was used to help it determine the project’s priorities — which can change from year to year — as well as a guide for its development efforts and community engagement strategies for the upcoming year and beyond. The surveys are helpful for identifying user needs, assessing satisfaction levels, and highlighting areas requiring improvement, such as hardware support, documentation, and contribution processes.' -- source: https://fossforce.com/2025/04/freebsd-wants-to-know-a-few-things/ Link to survey in the referenced article. Anybody on the mailing list using a BSD variant currently? Cheers, Peter
