  • panfrost: Resolves graphical artifacts on T604 (T600), fixes intermittent compiler failures when building valhall tests, and pads compute jobs with zeros on v4.
  • radeonsi: Fixes unsynchronized flips/tearing with KMS DRM rendering on 780M and addresses heavy corruption in Amnesia: The Dark Descent.
  • VK: Various fixes for flaky tests, fullscreen “banding” artifacts in Age of Empires IV, and failures in dEQP-VK pipeline tests.
• systemd: Updates to version 254.9.
  • vconsole-setup: Resolved issue where vconsole-setup would fail if the only found vc is already used by plymouth.
  • systemd-testsuite: Dependency updated to “qemu” instead of “qemu-kvm”, the latter being obsolete.
  • test/test-shutdown.py: Option added to display test I/Os in a dedicated log file.
  • man pages: Documentation update to include ranges for distributions config files and local config files.
  • libbpf: Version of libbpf dlopened by systemd updated (weak dependency).
• glibc: Updated from version 2.38 to 2.39,
  • PLT Rewrite: Introduction of a new tunable, glibc.cpu.plt_rewrite, allows for enabling PLT rewrite on x86-64 architectures.
  • Sync with Linux Kernel 6.6: Synchronization with Linux kernel 6.6 shadow stack interface.
  • New Functions: Addition of new functions on Linux, including posix_spawnattr_getcgroup_np, posix_spawnattr_setcgroup_np, pidfd_spawn, pidfd_spawp, and pidfd_getpid.
  • scanf-family functions: Support for the wN format length modifiers for arguments pointing to specific types.
  • Memory Allocation Tunable: Introduction of a new tunable, glibc.mem.decorate_maps, for adding additional information on underlying memory allocated by glibc.
  • ISO C2X: Inclusion of the <stdbit.h> header from ISO C2X.
  • AArch64: Addition of new symbols to libmvec on AArch64.
  • ldconfig Enhancements: ldconfig now skips file names containing specific characters and patterns.
  • Dynamic Linker Improvements: The dynamic linker calls the malloc and free functions in more cases during TLS access if a shared object with dynamic TLS is loaded and unloaded.
• Cups-Filters: Updates to version 1.28.17
  • Improved Printer Capability Discovery: Enhancements to more reliably discover all printer capabilities from driverless printers, particularly borderless printing. This includes preferring Apple Raster over PWG Raster or PCLM formats.
  • PPD Generator Optimization: The PPD generator now creates only one *cupsFilter2 line for raster, utilizing the most desirable/reliable format, usually Apple Raster.
  • Media Database Handling: Enhancements in handling media-col-database and media-col-ready IPP attributes separately if needed, revealing important functionality like borderless printing.
  • Margin Alternatives Consideration: Consideration of all margin alternatives when generating PPD files for driverless printers, ensuring the discovery of borderless functionality for many printers.
  • Image Printing Enhancements: Images are now printed in their original size with “print-scaling=none”, and deprecated data types for reading TIFF images have been replaced with modern equivalents.
• openvpn: Updates to version 2.6.9
  • Enhanced Logging: SSL alerts are now logged more prominently, improving visibility into SSL-related issues.
  • Documentation Improvements: Clarifications and additions to documentation, including the documentation of the tls-exit option as a primarily test option.

Security Updates

This month’s updates include critical security patches and bug fixes for glibc, GStreamer, Salt, Xen and many other packages.

Bug Fixes

• glibc: Had a few Common Vulnerabilities and Exposures fixed. CVE-2023-6246, CVE-2023-6779, which was a buffer overflow, CVE-2023-6780, which was an integer overflow, both that lead to an incorrect calculation of the buffer size.
• GStreamer: CVE-2024-0444 made it possible for a malicious third party to trigger a crash in the application.
• Salt: CVE-2024-22231 was vulnerable to a directory traversal attack and CVE-2024-22232, with a specially crafted url, could lead to a directory traversal in the salt file server.
• Xen: CVE-2023-46839 had a high complexity and required high privileges.
• dnsmasq: Both CVE-2023-50387 and CVE-2023-50868 could allow for remote attackers to cause a denial of service.
• qemu: CVE-2023-6693 could allow a hacker to steal data via a network device.
• bind: CVE-2023-50387 was associated with a “KeyTrap” DNS flaw lets attackers overload servers remotely. The other three were CVE-2023-4408, CVE-2023-5679 and CVE-2023-6516.
• Node.js: Multiple CVEs were fixed. These were CVE-2024-21892, which let unprivileged users gain elevated rights, CVE-2024-22019, which was a flaw that let attackers crash servers with malformed requests, and CVE-2024-22017, which was a path traversal bug via Buffer manipulation in an experimental feature. There was also CVE-2024-21896, CVE-2023-46809, CVE-2024-21891, CVE-2024-21890, CVE-2024-22025 and CVE-2024-24758, which kept Proxy-Authentication headers after redirects; upgrade as needed.
