Apologies for cross-posting. Cheers, Peter ---------- Forwarded message ---------- From: Mark Foster <...> Date: Thu, Mar 29, 2018 at 9:20 AM Subject: [NZLUG] [Fwd: [Security-news] Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-002] To: nzlug(a)lists.nzoss.org.nz I know there's plenty of Drupal out there, and I don't usually forward these around, but in case you havn't heard... The Drupal team took the unusual step of warning that this was coming several days ago, that helps set the tone for the severity of this. I've taken the unusual step of disabling my own Drupal based website until I can attend to its update. Mark. ---------------------------- Original Message ---------------------------- Subject: [Security-news] Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-002 From: security-news(a)drupal.org Date: Thu, March 29, 2018 8:21 am To: security-news(a)drupal.org -------------------------------------------------------------------------- View online: https://www.drupal.org/sa-core-2018-002 Project:Â Drupal core [1] Date:Â 2018-March-28 Security risk:Â *Highly critical* 21âˆ•25 AC:None/A:None/CI:All/II:All/E:Theoretical/TD:Default [2] Vulnerability:Â Remote Code Execution Description:Â CVE: CVE-2018-7600 A remote code execution vulnerability exists within multiple subsystems of Drupal 7.x and 8.x. This potentially allows attackers to exploit multiple attack vectors on a Drupal site, which could result in the site being completely compromised. The security team has written an FAQ [3] about this issue. Solution:Â Upgrade to the most recent version of Drupal 7 or 8 core. * *If you are running 7.x, upgrade to Drupal 7.58 [4].* (If you are unable to update immediately, you can attempt to apply this patch [5] to fix the vulnerability until such time as you are able to completely update.) * *If you are running 8.5.x, upgrade to Drupal 8.5.1 [6].* (If you are unable to update immediately, you can attempt to apply this patch [7] to fix the vulnerability until such time as you are able to completely update.) Drupal 8.3.x and 8.4.x are no longer supported and we don't normally provide security releases for unsupported minor releases [8]. However, given the potential severity of this issue, we /are/ providing 8.3.x and 8.4.x releases that includes the fix for sites which have not yet had a chance to update to 8.5.0. Your site's update report page will recommend the 8.5.x release even if you are on 8.3.x or 8.4.x. Please take the time to update to a supported version after installing this security update. * If you are running 8.3.x, upgrade to Drupal 8.3.9 [9] or apply this patch [10]. * If you are running 8.4.x, upgrade to Drupal 8.4.6 [11] or apply this patch [12]. This issue also affects Drupal 8.2.x and earlier, which are no longer supported. If you are running any of these versions of Drupal 8, update to a more recent release and then follow the instructions above. This issue also affects Drupal 6. Drupal 6 is End of Life. For more information on Drupal 6 support please contact a D6LTS vendor [13]. Reported By:Â * Jasper Mattsson [14] Fixed By:Â * Jasper Mattsson [15] * Samuel Mortenson [16] Provisional Drupal Security Team member * David Rothstein [17] of the Drupal Security Team * Jess (xjm) [18] of the Drupal Security Team * Michael Hess [19] of the Drupal Security Team * Lee Rowlands [20] of the Drupal Security Team * Peter Wolanin [21] of the Drupal Security Team * Alex Pott [22] of the Drupal Security Team * David Snopek [23] of the Drupal Security Team * Pere Orga [24] of the Drupal Security Team * Neil Drumm [25] of the Drupal Security Team * Cash Williams [26] of the Drupal Security Team * Daniel Wehner [27] * Tim Plunkett [28] -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached by email at security at drupal.org or via the contact form.

Chromebooks In Schools?
by Lawrence D'Oliveiro 28 Mar '18

28 Mar '18

In among this article about Apple’s new push to get IPads used in schools <https://arstechnica.com/gadgets/2018/03/analysis-new-ipads-will-help-apple-…> is the interesting information that Google Chromebooks are heavily used throughout the US school system: Google offers G Suite for Education for free, sans some features. Adding the full suite of enterprise features costs only $4 per user per month, compared to $25 per user per month for other kinds of organizations. Papers are typed in Google Docs. Presentations are done using Google Presentations. Each student has a Google email account assigned through the district. Homework is handed out and done entirely on Chromebooks in many classes. In so many words, Google has spread its tentacles throughout the entire school district at every level ... Are Chromebooks used in schools here? I noticed a couple of units on sale in OfficeMax when I dropped in there a few weeks ago. I don’t recall seeing them anywhere else in town.

Bring your own Linux to Windows with new open source tool
by Peter Reutemann 27 Mar '18

27 Mar '18

'After starting with Ubuntu, Microsoft has added a number of Linux distributions to its Windows Subsystem for Linux (WSL) Linux runtime environment. A Windows machine can simultaneously offer an Ubuntu, SUSE, Debian, and Kali "personality," providing users with a choice of the different distributions' preferences and package management. But if your distribution isn't yet available or if you want a Linux installation that's customized just the way you like it, there's now an answer: Microsoft has an open source tool for building your own Linux package. The tool is aimed at two groups: distribution owners (so they can produce a bundle to ship through the Microsoft Store) and developers (so they can create custom distributions and sideload them onto their development systems). Microsoft's tool provides the basic glue between Windows and the Linux distribution. It handles telling the system about the distribution and performing initial setup such as user creation, and it can be customized to—for example—print a message of the day when the distribution is started.' -- source: https://arstechnica.com/gadgets/2018/03/microsofts-new-open-source-tool-let… 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/

As predicted, more speculative execution processor attacks are discovered
by Peter Reutemann 26 Mar '18

26 Mar '18

'Researchers from the College of William and Mary, Carnegie Mellon, the University of California Riverside, and Binghamton University have described a security attack that uses the speculative execution features of modern processors to leak sensitive information and undermine the security boundaries that operating systems and software erect to protect important data. That probably sounds familiar. The Spectre attacks, published earlier this year, take advantage of the speculative execution features of modern processors to leak sensitive information. The new attack, named BranchScope by the researchers, shares some similarity with variant 2 of the Spectre attack, as both BranchScope and Spectre 2 take advantage of the behavior of the processor's branch predictor.' -- source: https://arstechnica.com/gadgets/2018/03/its-not-just-spectre-researchers-re… 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/

Google starts blocking “uncertified” Android devices from logging in
by Peter Reutemann 26 Mar '18

26 Mar '18

'Google is apparently stepping up its efforts to crack down on illicit distribution of Google's Android apps. According to XDA Developers, Google logins on unlicensed devices will now fail at setup, and a warning message will pop up stating "Device is not certified by Google." This warning screen has appeared on and off in the past during a test phase, but XDA (and user reports) indicate it is now headed for a wider rollout.' -- source: https://arstechnica.com/gadgets/2018/03/google-starts-blocking-uncertified-… 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/

Kritia 4.0 Released, Conversation With The Team
by Lawrence D'Oliveiro 26 Mar '18

26 Mar '18

Another high-quality article from Alexandre Prokoudine <http://libregraphicsworld.org/blog/entry/krita-4-0-interview> about the just-released major revamp of Krita. It now straddles both “paint” and “draw” worlds, with Inkscape-styled SVG-based vector functionality added to the older paint functions. Oh, and it does animations as well. The item links to the “official” release video, but another informative one worth checking out is this <https://www.youtube.com/watch?v=OXvHHJUyBDg>.

Shodan Search Exposes Thousands of Servers Hosting Passwords and Keys
by Peter Reutemann 25 Mar '18

25 Mar '18

'Thousands of etcd servers "are spitting sensitive passwords and encrypted keys," reports Fossbytes: Security researcher Giovanni Collazo was able to harvest 8781 passwords, 650 AWS access keys, 23 secret keys, and 8 private keys. First, he ran a query on the hacker search engine Shodan that returned around 2300 servers running etcd database. Then, he ran a simple script that gave him the login credentials stored on these servers which can be used to gain access to CMSs, MySQL, and PostgreSQL databases, etc. etcd is a database used by computing clusters to store and exchange passwords and configuration settings between servers and applications over the network. With the default settings, its programming interface can return administrative login credentials without any authentication upfront... All of the data he harvested from around 1500 servers is around 750MB in size... Collazo advises that anyone maintaining etcd servers should enable authentication, set up a firewall, and take other security measures. Another security research independently verified the results, and reported that one MySQL database had the root password "1234".' -- source: https://developers.slashdot.org/story/18/03/24/1943239 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/

Facebook Scraped Call, Text Message Data For Years From Android Phones
by Peter Reutemann 25 Mar '18

25 Mar '18

'This past week, a New Zealand man was looking through the data Facebook had collected from him in an archive he had pulled down from the social networking site. While scanning the information Facebook had stored about his contacts, Dylan McKay discovered something distressing: Facebook also had about two years worth of phone call metadata from his Android phone, including names, phone numbers, and the length of each call made or received. This experience has been shared by a number of other Facebook users who spoke with Ars, as well as independently by us -- my own Facebook data archive, I found, contained call-log data for a certain Android device I used in 2015 and 2016, along with SMS and MMS message metadata. In response to an email inquiry about this data gathering by Ars, a Facebook spokesperson replied, "The most important part of apps and services that help you make connections is to make it easy to find the people you want to connect with. So, the first time you sign in on your phone to a messaging or social app, it's a widely used practice to begin by uploading your phone contacts." The spokesperson pointed out that contact uploading is optional and installation of the application explicitly requests permission to access contacts. And users can delete contact data from their profiles using a tool accessible via Web browser. If you granted permission to read contacts during Facebook's installation on Android a few versions ago -- specifically before Android 4.1 (Jelly Bean) -- that permission also granted Facebook access to call and message logs by default. The permission structure was changed in the Android API in version 16. But Android applications could bypass this change if they were written to earlier versions of the API, so Facebook API could continue to gain access to call and SMS data by specifying an earlier Android SDK version. Google deprecated version 4.0 of the Android API in October 2017 -- the point at which the latest call metadata in Facebook user's data was found. Apple iOS has never allowed silent access to call data. You are able to have Facebook delete the data it collects from you, "but it's not clear if this deletes just contacts or if it also purges call and SMS metadata," reports Ars. Generally speaking, if you're concerned about privacy, you shouldn't share your contacts and call-log data with any mobile application.' -- source: https://yro.slashdot.org/story/18/03/25/056246 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/

Raspberry Pi 3 Model B+ Benchmarks Show Significantly Improved Performance
by Peter Reutemann 25 Mar '18

25 Mar '18

'Pi Day was marked this year by the launch of the Raspberry Pi 3 Model B+ as the next evolution to this $35 ARM single-board computer. Phoronix has now put out Raspberry Pi 3 B+ benchmarks showing that the Ethernet performance is indeed much faster now but still doesn't stack up to other high performance boards, the SoC temperature is noticeably lower than the very warm Raspberry Pi 3, and the overall performance is a nice upgrade while retaining the same price point as its predecessors. Follow up tests looking at the Wi-Fi performance also show the new 802.11ac dual-band wireless to be much faster as well.' -- source: https://hardware.slashdot.org/story/18/03/25/0556258 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/

Hate-Speech Laws In Europe
by Lawrence D'Oliveiro 24 Mar '18

24 Mar '18

<https://www.techdirt.com/articles/20180321/17581339475/spanish-hate-anti-te…>: People are being arrested and charged with speech having nothing to with promoting hate or terrorism. ... It's gotten so bad Amnesty International -- an entity that usually spends its time decrying the acts of dictators and brutal authoritarians -- has felt compelled to speak up about Spain's terrible speech laws. ... The report also notes several other European countries are also beginning to curtail the rights of their citizens in their quest to target hate speech and international terrorism. Germany's hate speech law roll out has been an unmitigated disaster and other countries like France and Italy seem all too willing to join Spain and Germany in killing satire, parody, and content they just don't agree with. All of this is being done under the heading of "public safety," but in reality, the public is no safer and will develop an unhealthy fear of their own governments.
