  • Lukas Vrabec: Why do you see DAC_OVERRIDE SELinux denials?
  • With So Many Eyeballs, Is Open Source Security Better? [Ed: Ask a FOSS company. Not VMware. VMware puts back doors in its proprietary software blobs.]

    Back in 1999, Eric Raymond coined the term "Linus' Law," which stipulates that given enough eyeballs, all bugs are shallow.

    Linus' Law, named in honor of Linux creator Linus Torvalds, has for nearly two decades been used by some as a doctrine to explain why open source software should have better security. In recent years, open source projects and code have experienced multiple security issues, but does that mean Linus' Law isn't valid?

    According to Dirk Hohndel, VP and Chief Open Source Officer at VMware, Linus' Law still works, but there are larger software development issues that impact both open source as well as closed source code that are of equal or greater importance.

  • The aftermath of the Gentoo GitHub hack [Ed: What a bad choice of password leads to.]

    Late last month (June 28), the Gentoo GitHub repository was attacked after someone gained control of an admin account. All access to the repositories was soon removed from Gentoo developers. Repository and page content were altered. But within 10 minutes of the attacker gaining access, someone noticed something was going on, 7 minutes later a report was sent, and within 70 minutes the attack was over. Legitimate Gentoo developers were shut out for 5 days while the dust settled and repairs and analysis were completed.

  • New Variant of Spectre Security Flaw Discovered: Speculative Buffer Overflows

    Security researchers Vladimir Kiriansky (MIT) and Carl Waldspurger (Carl Waldspurger Consulting) have published a paper to disclose a new variant of the infamous Spectre security vulnerability, which creates speculative buffer overflows.

    In their paper, the two security researchers explain the attacks and defenses for the new Spectre variant they discover, which they call Spectre1.1 (CVE-2018-3693), a new variant of the first Spectre security vulnerability unearthed earlier this year and later discovered to have multiple other variants.

    The new Spectre flaw leverages speculative stores to create speculative buffer overflows. Similar to the classic buffer overflow security flaws, the new Spectre vulnerability is also known as "Bounds Check Bypass Store" or BCBS to distinguish it from the original speculative execution attack.

  • AT&T acquires open-source threat intelligence firm

    As AT&T continues down its network virtualization efforts using the open-source Open Networking Automation Platform (ONAP), the operator has acquired cybersecurity firm AlienVault, which uses open-source software to provide what the companies call “threat intelligence.” Financial details of the transaction were not disclosed; AT&T expects the deal to close in Q3 this year.

  • Malware Found in Arch Linux AUR Package Repository

    Malware has been discovered in at least three Arch Linux packages available on AUR (Arch User Repository), the official Arch Linux repository of user-submitted packages.

    The malicious code has been removed thanks to the quick intervention of the AUR team.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
