  • Reproducible Builds in May 2021

    In these reports we try to the most important things that we have been up to over the past month. As a quick recap, whilst anyone may inspect the source code of free software for malicious flaws, almost all software is distributed to end users as pre-compiled binaries. If you are interested in contributing to the project, please visit our Contribute page on our website.

  • SAML Implementation Vulnerability Impacting Some Akamai Services - The Akamai Blog

    This blog post provides an overview of a vulnerability discovered in Akamai's Enterprise Application Access (EAA) product which has been patched. This vulnerability could have allowed an actor to impersonate an authorized user when interacting with an application that used Security Assertion Markup Language Version 2 (SAMLv2, referred to as SAML in this document) to authenticate users.

    Following the initial notification from a third party, Akamai engineers identified that the vulnerability was in Lasso, a third-party, open source library which implements the SAML v2.0 authentication protocol. Lasso is the library that Akamai EAA uses to verify SAML assertions for applications when a customer configures SAML authentication with third-party identity provider(s) (IdPs). Further investigation of the Lasso library determined that the weakness had a wider impact on other software which has Lasso as a dependency.

    A comprehensive fix was deployed to the EAA network as of March 4th, 2021. No updates were required for the EAA connector appliances or the EAA Client. Akamai has determined that the SOGo and PacketFence packages maintained by Inverse, a company recently acquired by Akamai, also depend on Lasso for deployments using SAML for authentication. The SOGo package was also subject to another independent but related vulnerability, CVE-2021-33054. Information about the impact on SOGo and PacketFence may be found here. We have verified that all other external facing applications provided by Akamai, including Akamai Control Center, are not vulnerable to this attack vector.

  • Wireshark 3.4.6

    Wireshark is a network packet analyzer. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible. You could think of a network packet analyzer as a measuring device used to examine what's going on inside a network cable, just like a voltmeter is used by an electrician to examine what's going on inside an electric cable (but at a higher level, of course). In the past, such tools were either very expensive, proprietary, or both. However, with the advent of Wireshark, all that has changed. Wireshark is perhaps one of the best open source packet analyzers available today.

  • 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.
