Security Leftovers

  • Critical Exim Flaw Opens Millions of Servers to Takeover [Ed: This repeats the FUD headline from ZDNet's Bleeping Computer hire; no server is known to have been compromised by this yet. They dramatise this.]

    A critical vulnerability found in Exim servers could enable a remote, unauthenticated attacker to execute arbitrary code with root privileges.

  • Google Fortifies Kubernetes Nodes Against Boot Attacks

    Google released a beta version of its Shielded GKE Nodes that prevents an attacker from exploiting vulnerable Kubernetes nodes.

  • Spoofing commits to repositories on GitHub

    The situation that worries me relates to distribution packaging. Debian has a policy that deltas to packages in the stable repository should be as small as possible, targetting fixes by backporting patches from newer releases.

    If you get a bug report on your Debian package with a link to a commit on GitHub, you had better double check that this commit really did come from the upstream author and hasn’t been spoofed in this way. Even if it shows it was authored by the upstream’s GitHub account or email address, this still isn’t proof because this is easily spoofed in git too.

    The best defence against being caught out by this is probably signed commits, but if the upstream is not doing that, you can clone the repository from GitHub and check to see that the commit is on a branch that exists in the upstream repository. If the commit is in another fork, the upstream repo won’t have a ref for a branch that contains that commit.

  • For real this time, get your butt off Python 2: No updates, no nothing after 1 January 2020 [Ed: When Microsoft Tim says "according to Redmonk" he means mostly according to Microsoft (because Redmonk relies on proprietary GitHub for data)]

    Python 2 will sunset on January 1st 2020 – however, many applications have not yet upgraded to version 3, causing the coding lingo's team to mount a communications campaign to persuade devs to port their code.

    Python is the third most popular programming language after JavaScript and Java, according to Redmonk. Its use has been boosted by the strong interest in machine learning, for which Python is well suited, thanks in part to its various AI-related libraries and frameworks.

    Python 2.0 was released in 2000, and Python 3.0, which is not fully backwards compatible, in 2008. The last version of Python 2.x, 2.7, was released in July 2014.

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.
