Security: FOSS Updates, WhatsApp and Telegram, Windows as Malware and Respect to Fernando Corbató

  • Security updates for Monday

    Security updates have been issued by CentOS (firefox), Debian (libspring-java, ruby-mini-magick, and thunderbird), Fedora (fossil, python-django, snapd-glib, and thunderbird), openSUSE (helm and monitoring-plugins), Red Hat (cyrus-imapd, thunderbird, and vim), Scientific Linux (vim), Slackware (bzip2), SUSE (bubblewrap, bzip2, expat, glib2, kernel, php7, python3, and tomcat), and Ubuntu (exiv2, firefox, and flightcrew).

  • WhatsApp, Telegram Vulnerable To ‘Media File Jacking’: Change Your Settings Now!

    Instant messaging apps like WhatsApp and Telegram keep your messages encrypted in transit, but once a media file reaches your phone, the same cannot be guaranteed. Researchers from Symantec have demonstrated how a vulnerability in WhatsApp and Telegram can be exploited by hackers to hijack the media files that are sent through these services.

  • Windows 7 & security-only telemetry - What gives?

    Sometimes, it is hard to separate fact from emotion when it comes to technology. This does not help the end user, because when people come searching for solutions to genuine concerns like this, they first have to filter through outbursts of pent-up frustration as a result of many years of salesy bullshit. From the technological point of view, there's nothing new here. However, the fact you now get non-security nonsense with security means you can't really trust updates from Microsoft anymore. So if anything, this will majestically backfire. People don't like being pushed, and I'm amazed with the repeated attempts to do so, again and again.

  • Fernando Corbató, Early Operating System Pioneer And Password Inventor, Dies At 93

    Corbató and his fellow researchers at MIT made possible much of what we now think of as computing.

    Longtime MIT professor developed early “time-sharing” operating systems and is widely credited as the creator of the world's first computer password.

AMD's Linux Graphics Driver Patches

  • AMD resolves Destiny 2, Linux crashes via AGESA update

    AMD has confirmed that a bug causing Destiny 2 and selected Linux distributions to fail to run on its latest Zen 2-based Ryzen 3000 series processors will need a microcode update to resolve - but claims it has distributed the necessary code to its motherboard partners already. AMD's third-generation Ryzen processors, based on the company's Zen 2 microarchitecture, are undeniably impressive - but users of some software packages have been reporting incompatibility issues. For gamers, the headline was Destiny 2 refusing to run when running on any system with a Ryzen 3000 series processor installed; for Linux users, an incompatibility between the chips and selected versions of the systemd init system and related software suite. In both cases, the issue was the same: a complete inability to use the software without reverting to older hardware.

  • AMD Sends Out Linux Graphics Driver Patches For "Arcturus" As New Vega Derived GPU

    Remember last September when that AMD Arcturus codename dropped in our forums for what at first appeared to be a successor to Navi but later clarified to be used as a Linux driver enablement codename? Well, the Linux kernel driver patches for this "Arcturus" GPU have just been posted. This Radeon Arcturus support comes just a few weeks after the Radeon RX 5000 "Navi" Linux driver support was posted. But indeed this "Arcturus" part isn't based on Navi but rather a new swing on Vega based on Vega 20 in part. And we haven't heard of "Arcturus" at any recent AMD events nor from leaks on the more Windows focused sites.

Linux kernel announces a patch to allow 0.0.0.0/8 as a valid address range

Last month, the team behind Linux kernel announced a patch that allows 0.0.0.0/8 as a valid address range. This patch allows for these 16m new IPv4 addresses to appear within a box or on the wire. The aim is to use this 0/8 as a global unicast as this address was never used except the 0.0.0.0. In a post written by Dave Taht, Director of the Make-Wifi-Fast, and committed by David Stephen Miller, an American software developer working on the Linux kernel mentions that the use of 0.0.0.0/8 has been prohibited since the early internet due to two issues.

Coming up in Linux 5.3: ASUS TUF Gaming Laptop Support, Speed Select Technology (SST)

  • Linux 5.3's ASUS WMI Driver Add ASUS TUF Gaming Laptop Support & More

    The x86 platform driver updates were sent in and already merged for the ongoing Linux 5.3 kernel. It's the x86 platform driver updates that bring the recently mentioned Intel Speed Select Technology for Linux driver but there is also more. Beyond the interesting Intel Speed Select support, the ASUS WMI driver has gone through a refactoring in order to support ASUS' TUF Gaming laptops. In the process, there's even been a regression fix for once popular Eee PC laptop models where their backlight were stuck permanently off.

  • Intel Speed Select Technology Comes To Linux With The 5.3 Kernel

    With the in-development Linux 5.3 kernel is now support for Intel Speed Select Technology (SST) that was introduced as part of Cascade Lake processors. Speed Select Technology allows optimizing the system with per-core performance configurations to prioritize certain workloads while lowering the performance envelope for other cores. With the Linux 5.3 kernel there is now an Intel Speed Select Technology driver with these granular power/performance controls. With Cascade Lake and newer, these power and performance profiles can be configured from the OS and done dynamically based upon the real-time needs.
