security advisory vulnerability
security advisory vulnerability GNOME is officially shortening its standard vulnerability disclosure window from 90 days to 30 days, a change that impacts upstream maintainers, downstream Linux distributions, and system administrators in how they handle software vulnerabilities. The policy shift, announced by long-time security coordinator Michael Catanzaro , addresses modern software patching realities and a growing influx of automated submissions. . Because GNOME is the default desktop environment on several major Linux...

security advisory moderate For organizations that run a self-hosted Git platform, it’s no longer just about hosting static code repositories. Today, Git servers are responsible for deployment pipelines, API tokens, SSH keys, package repositories, and the automation scripts that push code directly. Confirm that the upgrade addresses known vulnerabilities but also provides production environments. . That makes them trusted systems within the development environment and attractive targets for attackers looking to move...

data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

security advisoryremote code executionmemory corruptionGNOME: CVE-2023-43641 Critical: Remote Code Execution Risk
A memory corruption vulnerability in the open-source libcue library can let attackers execute arbitrary code on Linux systems running the GNOME desktop environment. . libcue, a library designed for parsing cue sheet files, is integrated into the Tracker Miners file metadata indexer, which is included by default in the latest GNOME versions. Cue sheets (or CUE files) are plain text files containing the layout of audio tracks on a CD, such as length, name of song, and musician, and are also typically paired with the FLAC audio file format. GNOME is a widely used desktop environment across various Linux distributions such as Debian, Ubuntu, Fedora, Red Hat Enterprise, and SUSE Linux Enterprise. Attackers can successfully exploit the flaw in question (CVE-2023-43641) to execute malicious code by taking advantage of Tracker Miners automatically indexing all downloaded files to update the search index on GNOME Linux devices. . A flaw in libcue related to memory management permits malicious actors to execute unauthorized code on GNOME Linux platforms through the downloading of compromised files..

security advisorymoderatememory corruptionIntel: CVE-2022-4139 Moderate: Kernel Graphics Driver Data Leak Issue
CVE-2022-4139 was made public as an i915 kernel graphics driver security issue affecting all Gen12 graphics -- from integrated Tigerlake graphics up through the latest Raptor Lake graphics as well as the in-development Meteor Lake code plus the discrete GPUs of DG2/Alchemist and Arctic Sound. . Intel has disclosed CVE-2022-4139 as an incorrect GPU TLB flushing issue within their Linux kernel graphics driver. In some cases the translation lookaside buffer (TLB) is not flushed at all. At the very least there could be random memory corruption or data leaks while it's not yet been determined if specific memory could be targeted on affected Linux kernel versions up to this point. All versions from Linux 5.4 up through today's latest kernel versions are believed to be impacted when using Intel Gen12 integrated/discrete graphics. This though amounts to an Intel driver issue and not a hardware problem itself. Linus Torvalds just merged this five lines of code for mitigating the TLB invalidation on Intel Gen12 graphics for the video and compute engines.

Last summer, the GRUB bootloader was impacted by "BootHole" with security issues hitting its UEFI Secure Boot support. Now a new round of GRUB2 vulnerabilities affecting its UEFI Secure Boot support have been made public. . A new set of GRUB2 security vulnerabilities were made public today affecting its UEFI Secure Boot support. A set of eight CVEs were issued in 2020 and this year for the new issues. The issues include the possibility of specially crafted ACPI tables being loaded even if Secure Boot is active, memory corruption in GRUB's menu rendering, use-after-free in rmmod functionality, the cutmem command allowing privileged users to disable certain memory regions and in turn Secure Boot protections, arbitrary code execution even if Secure Boot is enabled, GRUB 2.05 accidentally re-introducing one of last year's vulnerabilities, and memory corruption from crafted USB device descriptors that could lead to arbitrary code execution.
