Name collisions aren't just a problem for software development—organizations, projects, and software that have the same or similar names can cause serious confusion. That was certainly the case on February 28 when the Open Collective Foundation (OCF) began to notify its hosted projects that it would be shutting down by the end of 2024. The announcement surprised projects hosted with OCF, as one might expect. It also worried and confused users of the Open Collective software platform from Open Collective, Inc. (OCI), as well as organizations hosted by the Open Source Collective (OSC) and Open Collective Europe (OC Europe). There is enough confusion about the names, relationships between the organizations, and impact on projects like Flatpak, Homebrew, and htop hosted by OCF, that a deeper look is warranted.

Security updates have been issued by Fedora (edk2, freeipa, kernel, and liblas), Oracle (kernel), Red Hat (docker, edk2, kernel, kernel-rt, and kpatch-patch), SUSE (axis, fontforge, gnutls, java-1_8_0-openjdk, kernel, python3, sudo, and zabbix), and Ubuntu (dotnet7, dotnet8, libgoogle-gson-java, openssl, and ovn).

Kaitlyn Abdo of Fedora's AI/ML SIG opened an issue with the Fedora Engineering Steering Committee (FESCo) recently that carried a few tricky questions about packaging machine-learning (ML) models for Fedora. Specifically, the SIG is looking for guidance on whether pre-trained weights for PyTorch constitute code or content. And, if the models are released under a license approved by the Open Source Initiative (OSI), does it matter what data the models were trained on? The issue was quickly tossed over to Fedora's legal mailing list and sparked an interesting discussion about how to handle these items, and a temporary path forward.

Security updates have been issued by Debian (composer and node-xml2js), Fedora (baresip), Mageia (fonttools, libgit2, mplayer, open-vm-tools, and packages), Red Hat (dnsmasq, gimp:2.8, and kernel-rt), and SUSE (389-ds, gdb, kernel, python-Django, python3, python36-pip, spectre-meltdown-checker, sudo, and thunderbird).

Sasha Levin has announced the release of the 6.8.1, 6.7.10, 6.6.22, 6.1.82, 5.15.152, 5.10.213, 5.4.272, and 4.19.310 stable kernels. As always, they contain important fixes throughout the tree. Users of those kernels should upgrade.

Zach Mitchell has announced the 1.0 release of Flox, a tool that lets its users install packages from nixpkgs inside portable virtual environments, and share those virtual environments with others as an alternative to Docker-style containers. Flox is based on Nix but allows users to skip learning how to work with the Nix language:

With Flox we're providing a substantially better user experience. We provide the suite of package manager functionality with install, uninstall, etc, but we also provide an entire new suite of functionality with the ability to share environments via flox push, flox pull, and flox activate --remote.

Flox is GPLv2-licensed, and releases are available as RPMs and Debian packages for x86_64 and arm64 systems.

Security updates have been issued by Debian (fontforge and imagemagick), Fedora (firefox), Mageia (cherrytree, python-django, qpdf, and sqlite3), Red Hat (bind, cups, emacs, fwupd, gmp, kernel, libreoffice, libX11, nodejs, opencryptoki, postgresql-jdbc, postgresql:10, postgresql:13, and ruby:3.1), Slackware (gnutls and mozilla), and Ubuntu (firefox, linux, linux-bluefield, linux-gcp, linux-gkeop, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-iot, linux-kvm, linux-oracle, linux-oracle-5.4, linux-aws, linux-aws-5.4, linux-aws, linux-aws-6.5, and linux-oracle, linux-oracle-5.15).

The Python project has announced three security releases, 3.10.14, 3.9.19, and 3.8.19. In addition to the security fixes, these releases are notable for two reasons; they are the first to make use of GitHub Actions to perform public builds instead of building artifacts "on a local computer of one of the release managers", and the first since Python became a CVE Numbering Authority (CNA).

Python release team member Łukasz Langa said that being a CNA means Python is able to "ensure the quality of the vulnerability reports is high, and that the severity estimates are accurate." It also allows Python to coordinate CVE announcements with the patched versions of Python, as it has with two CVEs addressed in these releases. CVE-2023-6597 CVE-2024-0450 describes a flaw in CPython's zipfile module that made it vulnerable to a zip-bomb exploit. CVE-2024-0450 CVE-2023-6597 is an issue with Python's tempfile.TemporaryDirectory class which could be exploited to modify permissions of files referenced by symbolic links. Users of affected versions should upgrade soon.

Cockpit is an interesting project for web-based Linux administration that has received relatively little attention over the years. Part of that may be due to the project's strategy of minor releases roughly every two weeks, rather than larger releases with many new features. While the strategy has done little to garner headlines, it has delivered a useful and extensible tool to observe, manage, and troubleshoot Linux servers.

The GNOME project announced GNOME 46 (code-named "Kathmandu") on March 20. The release has quite a few updates and improvements across user applications, developer tools, and under the hood. One thing stood out while looking over this release—a major emphasis on Flatpaks as the way to acquire and update GNOME software.

Security updates have been issued by Debian (composer and nodejs), Fedora (w3m), Mageia (tomcat), Oracle (expat, firefox, go-toolset:ol8, grafana, grafana-pcp, nodejs:18, and thunderbird), Red Hat (dnsmasq, expat, kernel, kernel-rt, libreoffice, and squid), and SUSE (firefox, krb5, libvirt, and shadow).

On March 21, Redis Ltd. announced that the Redis "in-memory data store" project would now be released under non-free, source-available licenses, starting with Redis 7.4. The news is unwelcome, but not entirely unexpected. What is unusual with this situation is the number of Redis alternatives to choose from; there are at least four options to choose as a replacement for those who wish to stay with free software, including a pre-existing fork called KeyDB and the Linux Foundation's newly-announced Valkey project. The question now is which one(s) Linux distributions, users, and providers will choose to take its place.

Security updates have been issued by Debian (py7zr), Fedora (biosig4c++ and podman), Oracle (kernel, kernel-container, and ruby:3.1), Red Hat (.NET 7.0, bind9.16, curl, expat, grafana, grafana-pcp, kernel, kernel-rt, kpatch-patch, less, opencryptoki, and postgresql-jdbc), and Ubuntu (cacti).

The 6.8.3, 6.7.12, 6.6.24, and 6.1.84 stable kernel updates have been released. Each contains an important set of fixes. Note that 6.7.12 is the final release for the 6.7.y series, and that branch is now end-of-life. Users should move to the 6.8.y branch.

AlmaLinux has announced updated kernels for AlmaLinux 8 and 9 to address CVE-2024-1086, a use-after-free vulnerability in the kernel that could be exploited to gain local privilege escalation. This is notable because the fix marks a divergence between AlmaLinux and Red Hat Enterprise Linux (RHEL):

In January of this year, a kernel flaw was disclosed and named CVE-2024-1086. This flaw is trivially exploitable on most RHEL-equivalent systems. There are many proof-of-concept posts available now, including one from our Infrastructure team lead, Jonathan Wright (Dealing with CVE-2024-1086). In multi-user scenarios, this flaw is especially problematic.

Though this was flagged as something to be fixed in Red Hat Enterprise Linux, Red Hat has only rated this as a moderate impact.

The AlmaLinux project would also like to note that it is not impacted by the XZ backdoor. "Because enterprise Linux takes a bit longer to adopt those updates (sometimes to the chagrin of our users), the version of XZ that had the back door inserted hadn't made it further than Fedora in our ecosystem."

Among the numerous approaches to funding the development and advancement of open-source software, corporate sponsorship in the form of donations to umbrella organizations is perhaps the most visible. At SCALE21x in Pasadena, California, Duane O'Brien presented a slice of his recent research into the landscape of such sponsorship arrangements, with an overview of the identifiable trends of the past ten years and some initial insights he hopes are valuable for sponsors and community members alike.

The nominations have closed and campaigning is underway to see who will be the next Debian Project Leader (DPL). This year, two candidates are campaigning for the position Jonathan Carter has held for four eventful years: Sruthi Chandran and Andreas Tille. Topics that have emerged so far include how the prospective DPLs would spend project money, their opinions on handling controversial topics, and project diversity.

Wayne Davison has announced the release of rsync version 3.3.0, which contains a number of bug fixes and minor enhancements. Davison has also announced a change in maintainers and a move to a new GitHub project:

The github repos have moved to a new RsyncProject organization. Because various life events have been monopolizing my time, I reached out to Tridge [Andrew Tridgell] (the original author) and he has graciously agreed to get back into rsync work, along with Paul Mackerras, who was also an early contributor to rsync. This new team will be working mainly on maintenance tasks, and not so much on new features. If you want to get involved, feel free to reach out on the new discord RsyncProject channels.

The new GitHub organization is here.

Security updates have been issued by Debian (jetty9, libcaca, libgd2, tomcat9, and util-linux), Fedora (chromium, micropython, and upx), Mageia (chromium-browser-stable, dav1d, libreswan, libvirt, nodejs, texlive-20220321, and util-linux), Red Hat (less, nodejs:20, and varnish), Slackware (tigervnc), and SUSE (buildah, c-ares, cdi-apiserver-container, cdi-cloner-container, cdi- controller-container, cdi-importer-container, cdi-operator-container, cdi- uploadproxy-container, cdi-uploadserver-container, cont, curl, expat, go1.21, go1.22, guava, helm, indent, krb5, kubevirt, virt-api-container, virt-controller-container, virt-exportproxy-container, virt-exportserver-container, virt-handler-container, virt-launcher-container, virt-libguestfs-t, libcares2, libvirt, ncurses, nghttp2, podman, postfix, python-Django, python-Pillow, python310, qemu, rubygem-rack, thunderbird, ucode-intel, and xen).
