Researchers from the University of Waterloo and the U.S. Naval Research Laboratory have unveiled results from the development of a Tor network simulator, comparable in the number of nodes and users to the main Tor network, allowing for experiments that closely resemble real-world conditions. The toolkit and methodology prepared during the experiment enabled simulation of a network with 6,489 nodes on a computer with 4 TB of RAM […]
The LLVM project has announced a transition from its mailing list system to the llvm.discourse.group site based on the Discourse platform for developer communication and announcements. By January 20, all archives of past discussions will be transferred to the new platform. The mailing lists will switch to a read-only mode on February 1. This transition will simplify communication and make it more familiar for […]
Another vulnerability has been identified in the eBPF subsystem (CVE is not assigned), similar to yesterday's issue that allows a local unprivileged user to execute code at the Linux kernel level. The problem has been present since Linux kernel 5.8 and remains unpatched for now. A working exploit is expected to be released on January 18. The new vulnerability is caused by incorrect validation of eBPF programs being executed. In particular, the eBPF verifier does not appropriately […]
Christofer Dutz, the creator and lead developer of the free library set for industrial automation Apache PLC4X, who holds the position of Vice President at the Apache Software Foundation overseeing the Apache PLC4X project, has issued an ultimatum to corporations, expressing his willingness to cease development if he cannot resolve funding issues. His dissatisfaction stems from the fact that the usage of Apache PLC4X […]
The release of IPython 8.0 has taken place, an interactive shell for the Python language that combines the features of the Python interactive console and the Unix command line, providing flexible debugging, code editing, and data visualization tools. IPython is actively used in the scientific community for development, data processing, and interactive execution of applications related to libraries such as numpy, matplotlib, sympy, and scipy. The new version includes the ability to […]
Patrick Volkerding announced the formation of the third and final release candidate for the Slackware 15.0 distribution, which has reached the freeze stage with 99% of packages ready before release. A 3.4 GB (x86_64) installation image has been prepared for download, along with a minimal build for live mode. Among the final changes before the freeze is the update of the Linux kernel to version 5.15.14 (consideration is being given to […]
A vulnerability (CVE-2021-3997) has been identified in the systemd utility systemd-tmpfiles, allowing for uncontrolled recursion. This issue can be exploited to create a denial of service during system boot by generating a large number of nested subdirectories in the /tmp directory. A patch is currently available as a fix. Package updates addressing the issue have been proposed in Ubuntu and SUSE but are not yet available in […]
A vulnerability (CVE-2021-4204) has been discovered in the eBPF subsystem, which allows running handlers inside the Linux kernel in a special JIT virtual machine, enabling a local unprivileged user to escalate privileges and execute their code at the Linux kernel level. The issue has been present since Linux kernel 5.8 and remains unfixed (affecting the 5.16 release as well). The status of the updates in development is […]
Jiri Konecny from Red Hat announced efforts to modernize and improve the user interface of the Anaconda installer used in Fedora, RHEL, CentOS, and some other Linux distributions. Notably, instead of using the GTK library, the new interface will be built on web technologies and will allow for remote management via a web browser. It is noted that the decision to revamp the installer has already […]
A release of the specialized Tails 4.26 distribution (The Amnesic Incognito Live System) has been formed, based on the Debian package base and designed for anonymous internet browsing. Anonymous access in Tails is provided by the Tor system. All connections, except traffic through the Tor network, are blocked by the firewall by default. For storing user data in persistent mode between boots, […] is used.
The release of the SDL 2.0.20 library (Simple DirectMedia Layer) has taken place, aimed at simplifying the development of games and multimedia applications. The SDL library provides tools such as hardware-accelerated output of 2D and 3D graphics, input processing, sound playback, and 3D output via OpenGL/OpenGL ES/Vulkan, along with many other supporting operations. The library is written in C and is distributed under the zlib license. To utilize SDL’s capabilities, […]
The far2l project, which has been developing the Far Manager port for Linux, BSD, and macOS since 2016, has entered the beta testing stage, with corresponding changes committed to the repository on January 12. Currently, the port, described on the project page as a fork, supports both console and graphical modes, with plugins such as colorer, multiarc, tmppanel, align, autowrap, drawline, editcase, SimpleIndent, […]
