New FreeBSD Code of Conduct
by Peter Reutemann 13 Jun '20

13 Jun '20

'FreeBSD has has adopted a new LLVM-derived code of conduct. The code of conduct requires users to: be friendly and patient, be welcoming, be considerate, be respectful, be careful in the words that you choose and be kind to others, when we disagree, try to understand why. This isn't an exhaustive list of things that you can't do. Rather, take it in the spirit in which it's intended - a guide to make it easier to communicate and participate in the community. This code of conduct applies to all spaces managed by the FreeBSD project. This includes online chat, mailing lists, bug trackers, FreeBSD events such as the developer meetings and socials, and any other forums created by the project that the community uses for communication. It applies to all of your communication and conduct in these spaces, including emails, chats, things you say, slides, videos, posters, signs, or even t-shirts you display in these spaces. In addition, violations of this code outside these spaces may, in rare cases, affect a person's ability to participate within them, when the conduct amounts to an egregious violation of this code.' -- source: https://developers.slashdot.org/story/20/06/12/1430203 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/

Canonical Releases Important Ubuntu Kernel Security Updates, Patch Now
by Peter Reutemann 12 Jun '20

12 Jun '20

'Canonical already released the other day a new version of the intel-microcode firmware to mitigate the latest Intel vulnerabilities, but now it also published new versions of the Linux kernel for all supported Ubuntu releases, including Ubuntu 20.04 LTS, Ubuntu 19.10, Ubuntu 18.04 LTS, and Ubuntu 16.04 LTS. Apart from mitigating the Intel SRBDS/CrossTalk vulnerability (CVE-2020-0543), the new Linux kernel security updates fix race conditions (CVE-2020-12114) discovered by Piotr Krysiuk in the file system implementation, which lets a local attacker cause a denial of service (system crash).' -- source: https://www.linuxtoday.com/security/canonical-releases-important-ubuntu-ker… 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/

Hands on with Android 11 Beta 1—A new media player and suggested apps
by Peter Reutemann 12 Jun '20

12 Jun '20

'Android 11's first "beta" release is finally out after numerous delays. The beta release works on the Pixel 2, 3, 3a, and 4, and enrolling for the beta OTA at google.com/android/beta. is super easy. Previously, the Android beta has launched simultaneously on plenty of third-party devices, but that's not the case this year. So far, OnePlus has also shipped the beta, and that's about it. Google says that more devices are coming "in the coming weeks." The Android 11 Beta has gone through a wild ride. First, it was supposed to debut at the Shoreline Amphitheater for Google I/O in May 12, but the physical event was canceled due to the coronavirus outbreak. Then it was supposed to debut in an online version of Google I/O, but that was canceled, too, as everyone was still trying to deal with the logistics problems the new shelter-in-place requirements. With no release in May, a surprise fourth preview release of Android 11 was created, and the Beta was delayed until June 3, when Google would hold an online event for "The Android 11 Beta Launch Show." The online Android 11 launch show was delayed, too, due to the ongoing nationwide protests against police brutality and the death of George Floyd. In its latest blog post, Google says the online launch show is also canceled entirely, and, surprise, the company is pressing the launch button now with zero fanfare. Not since Google canceled the launch of the Nexus 4 due to Hurricane Sandy in 2012 has a Google launch been such a hot, hot mess. With the Android 11 Beta finally go for launch, we're still seeing a bit of a mini I/O, even though every event is canceled. Google posted two blog posts, lots of documentation, and 12 videos covering new aspects of Android 11. The company is also planning "11 weeks of Android," a series that will see new developer talks posted each week. So far, the lack of fanfare seems appropriate for Android 11, which seems like a smaller release than we've gotten in previous years. This beta only has two new standout features we can point to.' -- source: https://arstechnica.com/gadgets/2020/06/hands-on-with-android-11-beta-1-a-n… 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/

UPnP flaw exposes millions of network devices to attacks over the Internet
by Peter Reutemann 12 Jun '20

12 Jun '20

'Millions of routers, printers, and other devices can be remotely commandeered by a new attack that exploits a security flaw in the Universal Plug and Play network protocol, a researcher said. CallStranger, as the exploit has been named, is most useful for forcing large numbers of devices to participate in distributed denial of service—or DDoS—attacks that overwhelm third-party targets with junk traffic. CallStranger can also be used to exfiltrate data inside networks even when they’re protected by data loss prevention tools that are designed to prevent such attacks. The exploit also allows attackers to scan internal ports that would otherwise be invisible because they’re not exposed to the Internet. Billions of routers and other so-called Internet-of-things devices are susceptible to CallStranger, Yunus Çadırcı, a Turkish researcher who discovered the vulnerability and wrote the proof-of-concept attack code that exploits it, wrote over the weekend. For the exploit to actually work, however, a vulnerable device must have UPnP, as the protocol is known, exposed on the Internet. That constraint means only a fraction of vulnerable devices are actually exploitable.' -- source: https://arstechnica.com/information-technology/2020/06/upnp-flaw-exposes-mi… 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/

Linux distro review: System76’s Ubuntu-based Pop!_OS
by Peter Reutemann 12 Jun '20

12 Jun '20

'The subject of today's Linux distro review is perhaps one of a kind—as far as we know, Pop!_OS is the first Linux distribution to be created and maintained by a hardware OEM manufacturer. At the very least, it's the first one anyone has taken seriously. That hardware manufacturer is System76, probably the world's best-known Linux-only laptop manufacturer. Some larger OEMs offer Linux as an alternative operating system on a few models—but System76 sells Linux systems, and only Linux systems. Until 2017, System76 sold its systems preinstalled with Ubuntu Linux. But Canonical left the company cold when it decided to stop development on its Unity desktop environment and move back to Gnome3—and, controversially, System76 decided that instead of merely adding its own private repository and a few packages to a stock Ubuntu install, it would create and manage its own Ubuntu-derived distribution. Crucially, the new distribution would not just be for System76 hardware. Although the company uses the new distro to simplify and retain more control over its hardware setup, it designed Pop!_OS to be a real distro suitable for use—and encouraged for use—on any Linux PC, whether purchased from System76 or not.' -- source: https://arstechnica.com/gadgets/2020/06/linux-distro-review-system76s-ubunt… 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/

System76 Launches AMD Ryzen-Powered 'Serval WS' Portable Linux Workstation
by Peter Reutemann 12 Jun '20

12 Jun '20

'Linux computer maker/seller System76 has been offering AMD processors in its Thelio desktop computers, but believe it or not, the company has never offered an AMD-powered laptop -- until now, that is. From a report: You see, starting today, you can buy a "Serval WS" powered by AMD. No, System76 is not offering mobile Ryzen chips in this laptop, but instead, desktop-class processors. As you can expect, this 15-inch portable Linux workstation is quite chunky and heavy as a result. With that said, it is simply impossible to cram this much power into a thin and light notebook. "The Serval WS comes with either the 3rd Gen Ryzen 3600, 3700X, or 3900 CPU. The latter is equipped with 12 Cores and 24 Threads, making this laptop perfect for taking on heavy computational loads. Having this kind of desktop-caliber power in a laptop body helps if you need to run complex simulations at your desk or quickly render 3D scenes while on the road. AMD CPUs are also known for having the an extremely high price per performance, which means you get maximum bang-for-buck," says System76. The laptop starts at $1,300 -- and BetaNews has all the specs.' -- source: https://linux.slashdot.org/story/20/06/11/1634258 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/

Activists Rally To Save Internet Archive as Lawsuit Threatens Site
by Peter Reutemann 12 Jun '20

12 Jun '20

'The Internet Archive is a massive endeavor -- it's an online library aiming to "provide Universal Access to All Knowledge." It has digitized millions of web pages, movies, photos, recordings, software programs, and books that might otherwise be lost to history. But it's neither un-censorable nor outside the bounds of copyright law. And now open internet supporters are wondering how to save it before it disappears.

Android 11 Will Help You Rein In Zombie App Permissions
by Peter Reutemann 11 Jun '20

11 Jun '20

'With 2.5 billion users worldwide, Google has a responsibility to make its Android operating system as secure as possible. But the company has at times struggled to adequately vet apps in the Google Play Store, allowing malicious programs through that thousands or millions of users go on to download. With Google's release of the Android 11 Beta on Wednesday, though, the company is taking steps to make it even more difficult for rogue apps to grab your data even when they do slip by. From a report: Google has worked for years to incrementally tighten Android security under the hood. And the release of Android 11 is particularly focused on expanding privacy improvements to give you more control over what your apps can access and giving more ways to distribute software updates across Android's fragmented and disjointed device population. Android 10 addressed some of this as well, requiring that app developers request permissions and then reaffirm user choices more often. Android 11 adds a feature that allows developer to request one-time permissions for things like the microphone, camera, or location as an alternative to all or nothing. You can share your location with a friend through a chat app once, for example, without granting indefinite location access, or having to remember to wade back into settings to revoke the permission later. "We can see that people are actually leveraging these features from Android 10 and thinking about their choices when they're giving apps access to permissions," says Charmaine D'Silva, an Android product manager who works on privacy. "So building on that this time we've added even more controls." Android 11 will also rein in apps that you don't use very often, automatically revoking permissions if you don't open it for a still undetermined period of time. If you start using the app again you can always reinstate its access, but the permission won't be lurking forgotten. Google plans to experiment with different cutoffs after 60-90 days, with the goal of eliminating stray permissions without breaking functionality.' -- source: https://yro.slashdot.org/story/20/06/10/1730228 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/

Playing Around With the Fuchsia OS
by Peter Reutemann 11 Jun '20

11 Jun '20

'Security and software development company Quarkslab played around with Google's new Fuchsia operating system, which could one day replace Android on smartphones and Chrome OS on laptops. The researchers "decided to give a quick look at Fuchsia, learn about its inner design, security properties, strengths and weaknesses, and find ways to attack it." Here's what they concluded: Fuchsia's micro kernel is called Zircon. It is written in C++. [...] Contrary to every other major OS, it appears rather difficult to target the Zircon kernel directly. A successful RCE (Remote Code Execution) on the world-facing parts of the system (USB, Bluetooth, network stack, etc) will only give you control over the targeted components, but they run in independent userland processes, not in the kernel. From a component, you then need to escalate privileges to the kernel using the limited number of syscalls you can access with the handles you have. Overall, it seems easier to target other components rather than the kernel, and to focus on components that you can talk to via IPC and that you know have interesting handles. Overall, Fuchsia exhibits interesting security properties compared to other OSes such as Android. A few days of vulnerability research allowed us to conclude that the common programming bugs found in other OSes can also be found in Fuchsia. However, while these bugs can often be considered as vulnerabilities in other OSes, they turn out to be uninteresting on Fuchsia, because their impact is, for the most part, mitigated by Fuchsia's security properties. We note however that these security properties do not -- and in fact, cannot -- hold in the lowest layers of the kernel related to virtualization, exception handling and scheduling, and that any bug here remains exploitable just like on any other OS. All the bugs we found were reported to Google, and are now fixed. Again, it is not clear where Fuchsia is heading, and whether it is just a research OS as Google claims or a real OS that is vowed to be used on future products. What's clear, though, is that it has the potential to significantly increase the difficulty for attackers to compromise devices.
