  • Security updates for Monday [LWN.net]

    Security updates have been issued by Debian (php7.4, redis, snapd, twisted, webkit2gtk, and wpewebkit), Fedora (cyrus-imapd, nodejs, phpMyAdmin, polkit, snapd, webkit2gtk3, and xen), Gentoo (chromium), openSUSE (jaw, kubevirt, virt-api-container,, opera, polkit, and sphinx), Red Hat (ruby:2.6), Slackware (expat), and SUSE (kubevirt, virt-api-container, virt-controller-container, virt-handler-container, virt-launcher-container, virt-libguestfs-tools-container, virt-operator-container and polkit).

  • Stealing Bicycles by Swapping QR Codes

    Presumably they’re using camera, printers, and stickers to swap the codes on the bikes. And presumably the victim is charged for not returning the stolen bicycle.

  • [Older] Citi Bikes being swiped by joyriding scammers who have cracked the QR code

    Local scam artists are pedaling a new con.

    They’re stealing Citi Bikes by switching the QR scan codes on two bicycles near each other at a docking station, then waiting for an unsuspecting cyclist to try to unlock a bike with his or her smartphone app.

    The app doesn’t work for the rider but does free up the nearby Citi Bike with the switched code, where a thief is waiting, jumps on the bicycle and rides off.

    The ripped-off ride is worth only $3 by itself. But the victimized customer could be on the hook for the $1,200 bike if it ends up lost or stolen. They’re also left without a way to get around town.

    “It’s happening every day,” claims Hell’s Kitchen amateur sleuth Richard, who captured video of the con in action at the Citi Bike dock near the corner of West 43rd Street and 10th Avenue in Manhattan.

  • Building and running FIPS containers on Ubuntu 18.04 | Ubuntu

    Whether running on the public cloud or a private cloud, the use of containers is ingrained in today’s devops oriented workflows. Having workloads set up to run under the mandated compliance requirements is thus necessary to fully exploit the potential of containers. This article focuses on how to build and run containers that comply with the US and Canada government FIPS140-2 data protection standard.

Nasty Linux Kernel Stack Overflow Flaw Found and Patched

  • Nasty Linux Kernel Stack Overflow Flaw Found and Patched

    Here we go again. Another obnoxious security bug, CVE-2022-0435: A Remote Stack Overflow in The Linux Kernel was found by Appgate senior exploit developer Samuel Page while he was poking around at a Linux heap overflow security bug, CVE-2021-43267 from November 2021. Page’s discovery is a remotely and locally reachable stack overflow in the Linux kernel’s Transparent Inter-Process Communication (TIPC) protocol networking module.

    TIPC, as the name says, is used for intracluster communications. Cluster topology is managed using the concept of nodes and links between these nodes. Messages sent using TIPC can be sent over either UDP or Ethernet. So far, so good.

  • Linux platform is more secure than Microsoft Windows & Apple macOS

    Google’s Project Zero has published new research showing that Linux developers are faster than others at fixing security flaws. Surprisingly, developers seem to be working on maintaining Linux faster than Google’s own internal team. The Project Zero team studied fixed vulnerabilities reported between January 2019 and December 2021. They found that open-source programmers fixed Linux problems in an average of only 25 days. Additionally, Linux developers have been steadily reducing the number of days to patch security flaws. Back in 2019, developers patched flaws within a month’s time. Now, they often finish fixing bugs within two weeks.

  • Linux security

    Linux is a more secure and agile platform than Microsoft Windows and Apple macOS, according to a study by Google’s Project Zero. While Windows and macOS were earlier believed to be safer than Linux, thanks to regular security patches and constant updates.

    The Project Zero team found out developers at Linux are faster at fixing security bugs compared to other platforms. The report showed Linux does a better job than Google’s own teams at Chrome, Chrome OS and Android. The study looked at data between January 2019 and December 2021 to determine how much time developers took to fix security issues.

    Linux developers took 25 days and Apple took 69 days to close security issues, while Microsoft took 83 days. Google and Mozilla took 44 days and 46 days respectively to fix bugs.

  • 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.
