Security updates have been issued by Debian (chromium and trafficserver), Fedora (chromium), Mageia (apache-mod_jk, gnome-shell, kernel, kmod-xtables-addons, and kmod-virtualbox, kernel-linus, and python3), Oracle (container-tools:ol8, dovecot, emacs, expat, firefox, git-lfs, gtk3, kernel, nano, net-snmp, osbuild-composer, python3, python3.11, python3.12, ruby:3.3, and virt:ol and virt-devel:rhel), Slackware (boost), SUSE (kernel), and Ubuntu (configobj, cups, cups-browsed, cups-filters, libcupsfilters, and libppd).

Security researcher Simone Margaritelli has reported a new vulnerability in CUPS, the software that many Linux systems use to manage printers and print jobs. Margaritelli describes the impact of the attack by saying: A remote unauthenticated attacker can silently replace existing printers' (or install new ones) IPP urls with a malicious one, resulting in arbitrary command execution (on the computer) when a print job...

Danilo Krummrich gave a talk at Kangrejos 2024 focusing on the question of how the Rust-for-Linux project could improve at getting device and driver abstractions upstream. As a case study, he used some of his recent work that attempts to make it possible to write a PCI driver entirely in Rust. There wasn't time to go into as much detail as he would have...

Version 17 of the PostgreSQL database has been released. This release of PostgreSQL adds significant overall performance gains, including an overhauled memory management implementation for vacuum, optimizations to storage access and improvements for high concurrency workloads, speedups in bulk loading and exports, and query execution improvements for indexes. PostgreSQL 17 has features that benefit brand new workloads and critical systems alike, such as additions...

The online-privacy-focused Tor project has announced that it has "joined forces and merged operations" with the Tails OS Linux distribution. Countering the threat of global mass surveillance and censorship to a free Internet, Tor and Tails provide essential tools to help people around the world stay safe online. By joining forces, these two privacy advocates will pool their resources to focus on what matters...

The extensible scheduler class (sched_ext) enables the implementation of CPU schedulers as a set of BPF programs loaded from user space; it first hit the mailing lists in late 2022. Sched_ext has engendered its share of controversy since, but is currently slated to be part of the 6.12 kernel release. At the 2024 Linux Plumbers Conference, the growing sched_ext community held one of its...

Security updates have been issued by AlmaLinux (container-tools:rhel8, dovecot, emacs, expat, git-lfs, go-toolset:rhel8, golang, grafana, grafana-pcp, gtk3, kernel, kernel-rt, nano, python3, python3.11, python3.12, and virt:rhel and virt-devel:rhel), Debian (mediawiki and puredata), Fedora (chisel), Mageia (glib2.0, gtk+2.0 and gtk+3.0, and python-astropy), Red Hat (git-lfs, grafana, grafana-pcp, kernel, and kernel-rt), SUSE (kubernetes1.24, kubernetes1.25, kubernetes1.26, kubernetes1.27, kubernetes1.28, opensc, and python36), and Ubuntu (apparmor, apr, ca-certificates, linux, linux-aws,...

Here's a post on the Google Security Blog on how switching to a memory-safe language can quickly reduce vulnerabilities in a project, even if a large body of older code persists. This leads to two important takeaways: The problem is overwhelmingly with new code, necessitating a fundamental change in how we develop code. Code matures and gets safer with time, exponentially, making the returns...

The Vanilla OS project has published a blog post to answer questions that users have raised since the release of Vanilla OS 2. The post has information about the update strategy for the distribution, an enterprise version with support, and plans for an experimental version called Vanilla OS Vision. We are not planning for a potential Vanilla OS 3 because it is not yet...

In March, Danilo Krummrich announced the new Nova GPU driver — a successor to Nouveau for controlling NVIDIA GPUs. At Kangrejos 2024, Krummrich gave a presentation about what it is, why it's needed, and where it's going next. Hearing about the needs of the driver provoked extended discussion on related topics, including what level of safety is reasonable to expect from drivers, given that...

The "Linus and Dirk show" has been a fixture at Open Source Summit for as long as the conference has existed; it started back when the conference was called LinuxCon. Since Linus Torvalds famously does not like to give talks, as he said during this year's edition at Open Source Summit Europe (OSSEU) in Vienna, Austria, he and Dirk Hohndel have been sitting down...

Security updates have been issued by Debian (booth), Gentoo (Xpdf), Oracle (go-toolset:ol8, golang, grafana, grafana-pcp, kernel, libnbd, openssl, pcp, and ruby:3.3), Red Hat (container-tools:rhel8, go-toolset:rhel8, golang, kernel, and kernel-rt), SUSE (apr, cargo-audit, chromium, obs-service-cargo, python311, python36, quagga, traefik, and xen), and Ubuntu (intel-microcode, linux-azure-fde-5.15, and puma).

Almost a decade ago KDE e.V., the non-profit organization that supports KDE, started a process for selecting goals to help the community unite behind a common vision for where the project should go in the near future. KDE recently wrapped up its 2022-2024 cycle and announced the goals for 2024-2026 at Akademy on September 7, in Würzburg, Germany. This time around, KDE will be looking to...

Version 10.0.0 of the HarfBuzz text-shaping engine has been released. Notable changes in this release include Unicode 16.0.0 support, adding Cairo script as an output format for hb-view, and a number of bug fixes.

The project to enable the writing of kernel code in Rust has been underway for several years, and each kernel release includes more Rust code. Even so, some developers have expressed frustration at the time it takes to get new functionality merged, and an air of uncertainty still hangs over the project. At the 2024 Maintainers Summit, Miguel Ojeda led a discussion on the...
