Bill Toulas reports via BleepingComputer: Firmware security firm Binarly has released a free online scanner to detect Linux executables impacted by the XZ Utils supply chain attack, tracked as CVE-2024-3094. CVE-2024-3094 is a supply chain compromise in XZ Utils, a set of data compression tools and libraries used in many major Linux distributions. Late last month, Microsoft engineer Andres Freud discovered the backdoor in the latest version of the XZ Utils package while investigating unusually slow SSH logins on Debian Sid, a rolling release of the Linux distribution. The backdoor was introduced by a pseudonymous contributor to XZ version 5.6.0, which remained present in 5.6.1. However, only a few Linux distributions and versions following a "bleeding edge" upgrading approach were impacted, with most using an earlier, safe library version. Following the discovery of the backdoor, a detection and remediation effort was started, with CISA proposing downgrading the XZ Utils 5.4.6 Stable and hunting for and reporting any malicious activity. Binarly says the approach taken so far in the threat mitigation efforts relies on simple checks such as byte string matching, file hash blocklisting, and YARA rules, which could lead to false positives. This approach can trigger significant alert fatigue and doesn't help detect similar backdoors on other projects. To address this problem, Binarly developed a dedicated scanner that would work for the particular library and any file carrying the same backdoor. [...] Binarly's scanner increases detection as it scans for various supply chain points beyond just the XZ Utils project, and the results are of much higher confidence. Binarly has made a free API available to accomodate bulk scans, too.

"What a time we live in," writes Phoronix, "where Microsoft not only continues contributing significantly to the Linux kernel but doing so to further flesh out the design of the Linux kernel's Rust programming language support..." Microsoft engineer Wedson Almeida Filho has sent out the latest patches working on Allocation APIs for the Rust Linux kernel code and also in leveraging those proposed APIs [as] a means of allowing in-place module initialization for Rust kernel modules. Wedson Almeida Filho has been a longtime Rust for Linux contributor going back to his Google engineering days and at Microsoft the past two years has shown no signs of slowing down on the Rust for Linux activities... The Rust for Linux kernel effort remains a very vibrant effort with a wide variety of organizations contributing, even Microsoft engineers.

BrianFagioli shares a report from BetaNews: In a recent security announcement, Red Hat's Information Risk and Security and Product Security teams have identified a critical vulnerability in the latest versions of the 'xz' compression tools and libraries. The affected versions, 5.6.0 and 5.6.1, contain malicious code that could potentially allow unauthorized access to systems. Fedora Linux 40 users and those using Fedora Rawhide, the development distribution for future Fedora builds, are at risk. The vulnerability, designated CVE-2024-3094, impacts users who have updated to the compromised versions of the xz libraries. Red Hat urges all Fedora Rawhide users to immediately cease using the distribution for both work and personal activities until the issue is resolved. Plans are underway to revert Fedora Rawhide to the safer xz-5.4.x version, after which it will be safe to redeploy Fedora Rawhide instances. Although Fedora Linux 40 builds have not been confirmed to be compromised, Red Hat advises users to downgrade to a 5.4 build as a precautionary measure. An update reverting xz to 5.4.x has been released and is being distributed to Fedora Linux 40 users through the normal update system. Users can expedite the update by following instructions provided by Red Hat.

An anonymous reader shares a report: Mutterings of alarm are emerging from the cloisters of Red Hat after the world's largest management consultancy was hired to help the IBM subsidiary focus engineers on their highest-value work. Red Hat confirmed the partnership with McKinsey & Company to The Reg, sharing this extract from an email from CTO Chris Wright to the Global Engineering Team: "Hey everyone -- as I mentioned during the recent Q1 All Hands, my goal is to have Global Engineering recognized as the world's greatest open-source software engineering organization. This team is already doing amazing work, and we have several initiatives in progress to help us achieve the goal I've set. One of those is a partnership with McKinsey. The objective of this project is to help us understand and incorporate learnings on working models, development practices, and tooling from across the software industry. "We've heard your feedback in person, during All Hands, and through RHAS [the annual Red Hat Associate Survey]. This project will help us to identify and remove mundane tasks that drain your energy so that you can focus on the most engaging and highest value work â" to make your job better. The work with McKinsey is one piece of the overall plan to help us become the world's greatest open-source software engineering organization"

Michael Larabel reports via Phoronix: Given the recent change by Redis to adopt dual source-available licensing for all their releases moving forward (Redis Source Available License v2 and Server Side Public License v1), the Linux Foundation announced today their fork of Redis. The Linux Foundation went public today with their intent to fork Valkey as an open-source alternative to the Redis in-memory store. Due to the Redis licensing changes, Valkey is forking from Redis 7.2.4 and will maintain a BSD 3-clause license. Google, AWS, Oracle, and others are helping form this new Valkey project. The Linux Foundation press release shares: "To continue improving on this important technology and allow for unfettered distribution of the project, the community created Valkey, an open source high performance key-value store. Valkey supports the Linux, macOS, OpenBSD, NetBSD, and FreeBSD platforms. In addition, the community will continue working on its existing roadmap including new features such as a more reliable slot migration, dramatic scalability and stability improvements to the clustering system, multi-threaded performance improvements, triggers, new commands, vector search support, and more. Industry participants, including Amazon Web Services (AWS), Google Cloud, Oracle, Ericsson, and Snap Inc. are supporting Valkey. They are focused on making contributions that support the long-term health and viability of the project so that everyone can benefit from it."
