Red Hat responds to the Intel processor flaw

Thursday 4th of January 2018 11:25:47 PM
Red Hat suggests customers update their systems to protect against the Intel Meltdown processor flaw. Discovered some time ago, but only just yesterday brought into public view, the CPU flaw allows an attacker to bypass restrictions to gain access to privileged memory (which should be inaccessible) -- possibly stealing sensitive information from computer systems, mobile devices, and cloud deployments.

Kernel Side-Channel Attacks

Thursday 4th of January 2018 07:59:56 PM
An industry-wide issue was found with the manner in which many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. All three rely upon the fact that modern high performance microprocessors implement both speculative execution, and utilize VIPT (Virtually Indexed, Physically Tagged) level 1 data caches that may become allocated with data in the kernel virtual address space during such speculation.

Linux Kernels 4.14.11, 4.9.74, 4.4.109, 3.16.52, and 3.2.97 Patch Meltdown Flaw

Thursday 4th of January 2018 06:51:19 PM
Linux kernel maintainers Greg Kroah-Hartman and Ben Hutchings have released new versions of the Linux 4.14, 4.9, 4.4, 3.16, 3.18, and 3.12 LTS (Long Term Support) kernel series that apparently patch one of the two critical security flaws affecting most modern processors.

Reading privileged memory with a side-channel

Thursday 4th of January 2018 05:42:42 PM
We have discovered that CPU data cache timing can be abused to efficiently leak information out of mis-speculated execution, leading to (at worst) arbitrary virtual memory read vulnerabilities across local security boundaries in various contexts. Variants of this issue are known to affect many modern processors, including certain processors by Intel, AMD and ARM.

What you didn't know about Creative Commons

Thursday 4th of January 2018 01:09:37 PM
I attended film school, and later I taught at a film school, and even later I worked at a major film studio. There was a common thread through all these different angles of the creative industry: creators need content. Interestingly, one movement kept providing the solution, and that was free culture, or, as it has been formalized, Creative Commons.read more

Raspberry Pi 101 – An Introduction to the Raspberry Pi GPIO

An important feature of the Raspberry Pi is the row of GPIO pins, where GPIO stands for general purpose input/output. It will allow us to communicate between Pi and the outside world. We have 40pins on Pi, we count these pins from left to right out of which seventeen pins are GPIO pins. Different pins are used for the different functions and can be connected to a number of external peripherals such as buttons, lights, relays, sensors, etc. Read more

Containers, the GPL, and copyleft: No reason for concern

Though open source is thoroughly mainstream, new software technologies and old technologies that get newly popularized sometimes inspire hand-wringing about open source licenses. Most often the concern is about the GNU General Public License (GPL), and specifically the scope of its copyleft requirement, which is often described (somewhat misleadingly) as the GPL’s derivative work issue. One imperfect way of framing the question is whether GPL-licensed code, when combined in some sense with proprietary code, forms a single modified work such that the proprietary code could be interpreted as being subject to the terms of the GPL. While we haven’t yet seen much of that concern directed to Linux containers, we expect more questions to be raised as adoption of containers continues to grow. But it’s fairly straightforward to show that containers do not raise new or concerning GPL scope issues. Read more
