Linux Distro Elive Emerges Alive After 8-Year Hibernation
by Peter Reutemann 11 Sep '18

11 Sep '18

'Designed to run on minimal hardware, Elive is very much a passion project of its leader, Samuel F Baggen. Based on Debian, the first version took a bow in 2005. The second stable version made an appearance in 2010 and it has been a long eight years for the third stable version to become available. The Register: Elive has an impressively low bar to entry, with hardware requirements for the distribution coming in at 256 MB RAM and a 500 MHz CPU, meaning that some very elderly silicon is theoretically going to be able to enjoy the highly polished Enlightenment desktop. "Theoretically" because after The Register took Elive 3.0.0 out for a spin on a relatively low-powered laptop, we'd frankly baulk at running it on anything much slower than a 533MHz Core 2 with at least 512 MB RAM. However, the Enlightenment UI is undeniably an attractive desktop, particularly if a macOS-alike dock is your thing, and runs at an impressive lick even on hardware that lacks graphics acceleration. At its core, Elive is based on the Debian 8 distribution (aka Jessie), using the 3.16 kernel and version 0.17.6 of the Enlightenment X11 Window Manager. It comes replete with a full set of applications, including the ubiquitous LibreOffice and Gimp, along with a variety of productivity and entertainment tools, some of which are Elive's own. Unlike the previous version of Elive, 3.0.0 removes the requirement of donating to the project in order to install the thing locally (although Baggen was quick to tell The Reg that cost-free alternatives existed, but often with annoying processes).' -- source: https://linux.slashdot.org/story/18/09/11/1121223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Exploit Vendor Drops Tor Browser Zero-Day on Twitter
by Peter Reutemann 11 Sep '18

11 Sep '18

'Zerodium, a company that buys and sells vulnerabilities in popular software, has published details today on Twitter about a zero-day vulnerability in the Tor Browser, a Firefox-based browser used by privacy-conscious users for navigating the web through the anonymity provided by the Tor network. The vulnerability is a bypass of the NoScript extension that's included by default with all Tor Browser distributions. Once bypassed, an attacker can run malicious code inside the Tor Browser, code that under certain circumstances would have been stopped by NoScript. "This Tor Browser exploit was acquired by Zerodium many months ago as a zero-day and was shared with our government customers," Zerodium CEO Chaouki Bekrar told ZDNet in an interview. "We have decided to disclose this exploit as it has reached its end-of-life and it's not affecting Tor Browser version 8 which was released last week." The NoScript extension released a patch in record time today to fix the vulnerability, two hours after Zerodium dropped its code on Twitter.' -- source: https://tech.slashdot.org/story/18/09/10/216238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Working On Google Translate Integration In Firefox
by Peter Reutemann 10 Sep '18

10 Sep '18

' Back in 2014, Mozilla partnered with Bing to translate webpages via Firefox in a similar fashion to Chrome's implementation of Google Translate. The company also added support for Yandex Translate in Firefox 41 in mid-2015, but it went all dark soon after and very few updates were issued. Now, Mozilla is finally starting to add support for Google Translate to the translation engine built into Firefox. gHacks reports: While the feature is not fully functional yet, it is an indicator that Mozilla has not forgotten the translate feature completely. Users who enable the translate functionality in Firefox on about:config will notice that Google is the selected translation engine. Google Translate cannot be used currently in Firefox; the browser throws an error message when you hit the translate button in the UI. Bing and Yandex don't seem to work either at this point in time even though Firefox seems to try and translate the page. The "there has been an error translating this page" error is thrown eventually as well. Google Translate requires API access keys and that is usually only available if companies or users pay for the key. It is unclear if Mozilla plans to make a deal with Google or if users will be required to use their own API keys for the functionality. The latter would surely be very limiting.

Worries Arise About Security of New WebAuthn Protocol
by Peter Reutemann 10 Sep '18

10 Sep '18

'"A team of security researchers has raised the alarm about some cryptography-related issues with the newly released WebAuthn passwordless authentication protocol," reports ZDNet. "The new WebAuthn protocol will allow users of a device -- such as a computer or a smartphone -- to authenticate on a website using a USB security key, a biometric solution, or his computer or smartphone's password." But researchers say that because WebAuthn uses weak algorithms for the operations of registering a new device, they can pull off some attacks against it. "If converted into a practical exploit, the ECDAA attacks discussed in the article would allow attackers to steal the key from a [server's] TPM, which would allow attackers to effectively clone the user's hardware security token remotely," Arciszewski, one of the researchers, told ZDNet. "The scenarios that follow depend on how much trust was placed into the hardware security token," he added. "At minimum, I imagine it would enable 2FA bypasses and re-enable phishing attacks. However, if companies elected to use hardware security tokens to obviate passwords, it would allow direct user impersonation by attackers." Attacks aren't practical, and experts say the root cause relies in badly written documentation that may fool some implementers into supporting the old algorithms instead of newer and more solid ones. The FIDO Alliance was notified and has started work on updating its docs so it won't look like it's recommending ECDAA or RSASSA-PKCS1-v1_5. "PKCS1v1.5 is bad. The exploits are almost old enough to legally drink alcohol in the United States," Arciszewski said.' -- source: https://it.slashdot.org/story/18/09/10/0227233 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Popular VPNs Contained Code Execution Security Flaws, Despite Patches
by Peter Reutemann 10 Sep '18

10 Sep '18

'Researchers have uncovered vulnerabilities in popular virtual private network (VPN) software, ProtonVPN and NordVPN, which can lead to the execution of arbitrary code by attackers. From a report: Last week, Cisco Talos security researchers said the security flaws, CVE-2018-3952 and CVE-2018-4010, permit code execution by attackers on Microsoft Windows machines. The vulnerabilities are similar to a Windows privilege escalation security flaw uncovered by VerSprite, which is tracked as CVE-2018-10169. Security patches were applied in April by both clients to resolve the original security hole, but according to Talos, "despite the fix, it is still possible to execute code as an administrator on the system." The initial vulnerability was caused by similar design issues in both clients. The interface for both NordVPN and ProtonVPN execute binaries with the permission of a logged-in user, and this includes the selection of a VPN configuration option, such as a desired VPN server location. This information is sent to a service when "connect" is clicked by way of an OpenVPN configuration file. However, VerSprite was able to create a crafted OpenVPN file which could be sent to the service, loaded, and executed.' -- source: https://yro.slashdot.org/story/18/09/10/118217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Nearly Half of American Households Will Own a Smart Speaker by 2019, Study Says
by Peter Reutemann 10 Sep '18

10 Sep '18

'Almost half of American households will have a smart speaker by next year, according to a new study from Adobe. From a report: The study, released Monday, finds that 32% of the country already owns a smart speaker and another 16% plan on getting one this holiday season. And just as importantly, people are using those speakers. "Technology trends come and go, but we think voice is here to stay," said Colin Morris, director of product management for Adobe Analytics, in a statement. "Consumers continue to embrace voice as a means to engage their devices and the Internet. It's a trend that has fundamentally changed the face of computing." A notable indicator of the growing popularity of the speakers is how comfortable people are talking to the device in front of others. And that number is on the rise: 72% of smart speaker owners say they use voice assistants in front of others. (Only 29% of people without a smart speaker are comfortable with doing so.)' -- source: https://tech.slashdot.org/story/18/09/10/1833235 I thought, that this would be of interest, due to our Alexa topic last month.

'Touch command in Linux is used for changing file timestamps however one of the most common usages of touch command includes creating a new empty file. With the touch command, you can change access, modify and change time of files and folders in Linux. You can update the timestamps or modify them to a date in the past.' -- source: https://linuxhandbook.com/touch-command/ To be honest, I only ever use it to create an empty file...

Hollywood goes open source
by Peter Reutemann 10 Sep '18

10 Sep '18

'Out of 200 of the most popular movies of all time, the top 137 were either visual-effects driven or animated. What did many of these blockbusters have in common? They were made with open-source software. That was the message David Morin, chairman of the Joint Technology Committee on Virtual Production, brought to The Linux Foundation's Open Source Summit in Vancouver, Canada. To help movie makers bring rhyme and reason to open-source film-making, The Linux Foundation had joined forces with The Academy of Motion Picture Arts and Sciences to form the Academy Software Foundation. The academy is meant to be a neutral forum for open-source developers both in the motion picture and broader media industries to share resources and collaborate on technologies for image creation, visual effects, animation, and sound. The founding members include Blue Sky Studios, Cisco, DreamWorks Animation, Epic Games, Google Cloud, Intel, Walt Disney Studios, and Weta Digital. It's a true marriage of technology and media-driven businesses.' -- source: https://www.zdnet.com/article/hollywood-goes-open-source/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Despite 'Painful' Spectre Response, Linus Torvalds Says He Still Loves Speculative Execution
by Peter Reutemann 09 Sep '18

09 Sep '18

'At this year's Open Source Summit, Linus Torvalds sat for a wide-ranging "keynote" interview with Dirk Hohndel, chief open source officer at VMWare, which has been partially transcribed below. And Linus explained, among other things, why the last merge window was harder than others: One of the issues we have is when we've had these hardware security issues, and they've kept happening now, the last year -- they're kept under wraps. So we knew about the issue for the last several months, but because it was secret and we weren't allowed to talk about it, we couldn't do our usual open development model. We do the best we can, and people really care deeply about getting a good product out, but when you have to do things in secret, and when you can't use all the nice infrastructure for development and for testing that we have for all the usual code, it just is way more painful than it should be. And then that just means that, especially when the information becomes public during what is otherwise a busy period anyway, it's just annoying... I still love speculative execution. Don't get me wrong. I used to work for a CPU company. We did it in software, back when I worked there. I think a CPU has to do speculative execution. It's somewhat sad that then people didn't always think about or didn't always heed the warnings about what can go wrong when you take a few shortcuts in the name of making it slightly simpler for everybody, because you're going to throw away all that work anyway, so why bother to do it right. And that's when the security -- every single security problem we've had has been basically of that kind, where people knew that "Hey, this is speculative work. If something goes wrong we'll throw all the data away, so we don't need to be as careful as we would otherwise." I think it was a good lesson for the industry, but it was certainly not a fun lesson for us on the OS side, where we had to do a lot of extra work for problems that weren't our problems. It feels somehow unfair. I mean, when we have a security bug that was our own fault, it's like, "Okay, it was us screwing up. It's fair that we have to do all the work to then fix our own bugs." But it feels slightly less fair when you have to fix somebody else's... "The good news -- I mean the really good news, and I'm serious about this -- is that the bugs have become clearly more and more esoteric," Linus adds. "So it impacts fewer and fewer cases, and clearly hardware people at Intel and other places are now so aware of it that I'm hoping we're really getting to the dregs of the hardware security bugs, and going forward we'll have much fewer of them. I think we're going to the better days, when A.) we got the bugs fixed, and B.) people were thinking about them beforehand."' -- source: https://linux.slashdot.org/story/18/09/09/0048248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
