  • Microsoft Teams might have a few serious security issues [Ed: Microsoft is incapable of making software that actually works, as explained by a former insider]

    Security researchers have discovered four separate vulnerabilities in Microsoft Teams that could be exploited by an attacker to spoof link previews, leak IP addresses and even access the software giant's internal services.

    These discoveries were made by researchers at Positive Security who “stumbled upon” them while looking for a way to bypass the the Same-Origin Policy (SOP) in Teams and Electron according to a new blog post. For those unfamiliar, SOP is a security mechanism found in browsers that helps stop websites from attacking one another.

  • Microsoft informs customers of 'NotLegit' Azure bug

    Microsoft's Security Response Center has released a blog post explaining its response to the "NotLegit" bug in Azure that was discovered by cloud security company Wiz.

    Wiz said all PHP, Node, Ruby, and Python applications that were deployed using "Local Git" on a clean default application in Azure App Service since September 2017 are affected. They added that all PHP, Node, Ruby, and Python applications that were deployed in Azure App Service from September 2017 onward using any Git source -- after a file was created or modified in the application container -- were also affected.

  • 4-Year-Old Bug in Azure App Service Exposed Hundreds of Source Code Repositories

    A security flaw has been unearthed in Microsoft's Azure App Service that resulted in the exposure of source code of customer applications written in Java, Node, PHP, Python, and Ruby for at least four years since September 2017.

    The vulnerability, codenamed "NotLegit," was reported to the tech giant by Wiz researchers on October 7, 2021, following which mitigations have been undertaken to fix the information disclosure bug in November. Microsoft said a "limited subset of customers" are at risk, adding "Customers who deployed code to App Service Linux via Local Git after files were already created in the application were the only impacted customers."

  • New Linux Patches For AMD i2c Bus Sharing With The PSP [Ed: This is, in effect, a back door in AMD processors, akin to M.E. in all Intel processors]

    The newest Linux hardware support patches for the kernel revolve around i2c bus sharing support for newer SoCs where the i2c bus is being shared by AMD's Platform Security Processor (PSP). This i2c controller is based on common DesignWare IP but new kernel code is being crafted for handling that bus sharing between the kernel and the PSP co-processor.

  • Pete Zaitcev: Adventures in tech support

    OVH was pestering me about migrating my VPS from its previous range to the new (and more expensive) one. I finally agreed to that. Migrated the VM to the new host, it launches with no networking. Not entirely unexpected, but it gets better.

    The root cause is the DHCP server at OVH returning a lease with netmask /32. In that situation, it's not possible to add a default route, because the next hop is outside of the netmask.

    Seems like a simple enough problem, so I filed a ticket in OVH support, basically saying "your DHCP server supplies incorrect netmask, please fix it."

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.
