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.

9 Useful Examples of Touch Command in Linux
by Peter Reutemann 09 Sep '18

09 Sep '18

'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 09 Sep '18

09 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/

Tor Browser Gets a Redesign, Switches To New Firefox Quantum Engine
by Peter Reutemann 06 Sep '18

06 Sep '18

'The Tor Browser has rolled out a new interface with the release of v8. From a report: The Tor Browser has always been based on the Firefox codebase, but it lagged behind a few releases. Mozilla rolled out a major overhaul of the Firefox codebase in November 2017, with the release of Firefox 57, the first release in the Firefox Quantum series. Firefox Quantum came with a new page rendering engine, a new add-ons API, and a new user interface called the Photon UI. Because these were major, code-breaking changes, it took the smaller Tor team some time to integrate all of them into the Tor Browser codebase and make sure everything worked as intended. The new Tor Browser 8, released yesterday, is now in sync with the most recent version of Firefox, the Quantum release, and also supports all of its features. This means the Tor Browser now uses the same modern Photon UI that current Firefox versions use, it supports the same speed-optimized page rendering engine and has also dropped support for the old XUL-based add-ons system for the new WebExtensions API system used by Chrome, Opera, Vivaldi, Brave, and the rest of the Chromium browsers.' -- source: https://yro.slashdot.org/story/18/09/06/1651255 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/

400, 000 Websites Vulnerable Through Exposed .git Directories
by Peter Reutemann 06 Sep '18

06 Sep '18

'Open .git directories are a bigger cybersecurity problem than many might imagine, at least according to a Czech security researcher who discovered almost 400,000 web pages with an open .git directory possibly exposing a wide variety of data. From a report: Vladimir Smitka began his .git directory odyssey in July when he began looking at Czech websites to find how many were improperly configured and allow access to their .git folders within the file versions repository. Open .git directories are a particularly dangerous issue, he said, because they can contain a great deal of sensitive information. "Information about the website's structure, and sometimes you can get very sensitive data such as database passwords, API keys, development IDE settings, and so on. However, this data shouldn't be stored in the repository, but in previous scans of various security issues, I have found many developers that do not follow these best practices," Smitka wrote. Smitka queried 230 million websites to discover the 390,000 allowing access to their .git directories. The vast majority of the websites with open directories had a .com TLD with .net, .de, .org and uk comprising most of the others.' -- source: https://tech.slashdot.org/story/18/09/06/1954253 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/

Shutter screenshotting application - no edit button
by Peter Reutemann 05 Sep '18

05 Sep '18

Hi everyone In case you're a Shutter user for capturing screenshots, you may have noticed that the "Edit" button in the main window is disabled. Apparently, shutter hasn't been updated for a while and it is missing some older libraries, like on my Linux Mint 18. However, this is easily fixed: https://itsfoss.com/shutter-edit-button-disabled/ 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/
