Z-Wave Alliance Says Z-Wave Source Code Project Is Complete, Now Open And Widely Available To Members
by Peter Reutemann 15 Dec '22

15 Dec '22

'The Z-Wave Alliance, the Standards Development Organization (SDO) dedicated to advancing the smart home and Z-Wave technology, today announced the completion of the Z-Wave Source Code project, which has been published and made available on GitHub to Alliance members. From a report: The Z-Wave Source Code Project opens development of Z-Wave and enables members to contribute code to shape the future of the protocol under the supervision of the new OS Work Group (OSWG). The goal of the project is to provide a rich development environment that contains the relevant source code and sample applications to those seeking to play a direct role in the advancement of the Z-Wave standard. The quality and interoperability of products utilizing Z-Wave Source Code will also be enforced by a new mandatory Silicon & Stack Certification program. Full Z-Wave certification will continue to test and certify for Z-Wave S2 security, network connectivity, range, battery life, and interoperability including backwards and forwards compatibility. "The Z-Wave Alliance is deeply committed to the global smart home market," said Mitch Klein, Executive Director of the Z-Wave Alliance. "This year the smart home conversations have focused largely on Matter. Shiny and new, and with big brands supporting the initiative, Matter is bringing a lot of attention to the smart home. This makes it easy to overlook Z-Wave as the most established, trusted, and secure smart home protocol, that also happens to have the largest certified interoperable ecosystem in the market. We firmly expect that Z-Wave will play a key role in connecting devices and delivering the experience users really want."' -- source: https://tech.slashdot.org/story/22/12/14/1712247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Windows Driver-Signing Doesn’t Work
by Lawrence D'Oliveiro 14 Dec '22

14 Dec '22

Having Microsoft verify third-party drivers with a digital signature, so that Windows will block the loading of unsigned drivers, seemed like a good idea when it came in with Windows Vista. Enforcing quality control would remove a big source of crashes, as well as security loopholes. But it seems the execution falls somewhat short <https://arstechnica.com/information-technology/2022/10/no-fix-in-sight-for-…>. The system for revoking signatures for old, obsolete drivers that are discovered to have security vulnerabilities in them doesn’t seem to work very well, allowing miscreants to exploit this old code to gain control of Windows systems. This has been dubbed a “Bring Your Own Vulnerable Device/Driver” (BYOVD) attack. Microsoft’s own Vice President of “OS Security and Enterprise” continues to claim that “Windows has everything you need to block” buggy signed drivers. Yet the article’s author was unable to get the mechanism to work. And Microsoft itself appeared to have no interest in helping to fix that. It seems to me, one thing missing from the mechanism is a time limit on signature validity. By contrast, when you get SSL/TLS certs for your website, they are only valid for some fixed interval (e.g. a year for certs from traditional certificate authorities, 90 days for ones from Let’s Encrypt). This means that clients using such certificates do not need to maintain an ever-growing list of revoked ones to check against, since ones that are past their expiry date can be rejected anyway. If the cert for a Windows driver has expired, but the driver itself is still valid, Microsoft should be able to simply renew the certificate. But I guess if Microsoft’s servers are struggling just to distribute certificate revocations, having to push out renewals as well will likely just make things worse.

Term Of The Week: “Electronic Suppression Software”
by Lawrence D'Oliveiro 13 Dec '22

13 Dec '22

What is “Electronic Suppression Software” (ESS)? It’s the computer equivalent of the old accounting scam of keeping two sets of books -- the one where you record the real profits of the business, and the one you show to the tax department <https://www.nzherald.co.nz/business/ird-warns-businesses-of-severe-conseque…>. This software seems to work at retail point-of-sale (tills). There have been some international raids lately on those suspected of supplying or using such tools.

Xnspy Stalkerware Spied on Thousands of iPhones and Android Devices
by Peter Reutemann 13 Dec '22

13 Dec '22

'A little-known phone monitoring app called Xnspy has stolen data from tens of thousands of iPhones and Android devices, the majority whose owners are unaware that their data has been compromised. From a report: Xnspy is one of many so-called stalkerware apps sold under the guise of allowing a parent to monitor their child's activities, but are explicitly marketed for spying on a spouse or domestic partner's devices without their permission. Its website boasts, "to catch a cheating spouse, you need Xnspy on your side," and, "Xnspy makes reporting and data extraction simple for you." Stalkerware apps, also known as spouseware, are surreptitiously planted by someone with physical access to a person's phone, bypassing the on-device security protections, and are designed to stay hidden from home screens, which makes them difficult to detect. Once installed, these apps will silently and continually upload the contents of a person's phone, including their call records, text messages, photos, browsing history and precise location data, allowing the person who planted the app near-complete access to their victim's data. But new findings show many stalkerware apps are riddled with security flaws and are exposing the data stolen from victims' phones. Xnspy is no different.' -- source: https://yro.slashdot.org/story/22/12/12/1658208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Raspberry Pi Inventory Improving, Could Reach Pre-Pandemic Levels In 2023
by Peter Reutemann 13 Dec '22

13 Dec '22

'According to CEO Eben Upton, "hundreds of thousands" of Raspberry Pi Zero, 3A+, and 4 models should show up next year. Ars Technica reports: In a "Supply chain update" blog post ("It's good news!"), CEO Eben Upton wrote that Raspberry Pi has "set aside a little over a hundred thousand units, split across Zero W, 3A+, and the 2GB and 4GB variants of Raspberry Pi 4, for single-unit sales." During the pandemic-spurred component shortage, most of the Pis produced every month were going to businesses, leaving those in need of one or two for a project refreshing rpilocator and cursing their timing. Zeros will start showing up first, then 3A+, then different models of 4. Upton acknowledged this reality (and even linked the locator) and asked that people buy only from approved resellers and consider the Pico and Pico W lines for projects that might fit, as those lines remain strong. As of this morning, a few 3A+ and CM4 models showed an optimistic green on the rpilocator spreadsheet. Raspberry Pi will continue to serve its commercial and industrial customers, Upton wrote, but will "make sure that inventory-building behavior which would otherwise prolong the shortage for everybody else can't take place." Meanwhile, Raspberry Pi will increase the percentage of boards designated for single-unit sales. With that change and future chip allocations, Upton expects that by the end of the third quarter of 2023, things will be back to how they were before the Great Pi Shortage, with "hundreds of thousands of units available at any given time."

OSnews Decries 'The Mass Extinction of Unix Workstations'
by Peter Reutemann 12 Dec '22

12 Dec '22

'Anyone remember the high-end commercial UNIX workstations from a few decades ago — like from companies like IBM, DEC, SGI, and Sun Microsystems? Today OSnews looked back — but also explored what happens when you try to buy one today> : As x86 became ever more powerful and versatile, and with the rise of Linux as a capable UNIX replacement and the adoption of the NT-based versions of Windows, the days of the UNIX workstations were numbered. A few years into the new millennium, virtually all traditional UNIX vendors had ended production of their workstations and in some cases even their associated architectures, with a lacklustre collective effort to move over to Intel's Itanium — which didn't exactly go anywhere and is now nothing more than a sour footnote in computing history. Approaching roughly 2010, all the UNIX workstations had disappeared.... and by now, they're all pretty much dead (save for Solaris). Users and industries moved on to x86 on the hardware side, and Linux, Windows, and in some cases, Mac OS X on the software side.... Over the past few years, I have come to learn that If you want to get into buying, using, and learning from UNIX workstations today, you'll run into various problems which can roughly be filed into three main categories: hardware availability, operating system availability, and third party software availability. Their article details their own attempts to buy one over the years, ultimately concluding the experience "left me bitter and frustrated that so much knowledge — in the form of documentation, software, tutorials, drivers, and so on — is disappearing before our very eyes." Shortsightedness and disinterest in their own heritage by corporations, big and small, is destroying entire swaths of software, and as more years pass by, it will get ever harder to get any of these things back up and running.... As for all the third-party software — well, I'm afraid it's too late for that already. Chasing down the rightsholders is already an incredibly difficult task, and even if you do find them, they are probably not interested in helping you, and even if by some miracle they are, they most likely no longer even have the ability to generate the required licenses or release versions with the licensing ripped out. Stuff like Pro/ENGINEER and SoftWindows for UNIX are most likely gone forever.... Software is dying off at an alarming rate, and I fear there's no turning the tide of this mass extinction. The article also wonders why companies like HPE don't just "dump some ISO files" onto an FTP server, along with patch depots and documentation. "This stuff has no commercial value, they're not losing any sales, and it will barely affect their bottom line.' -- source: https://tech.slashdot.org/story/22/12/12/0116206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Kernel Fixes Longstanding Bug in Its Handling of Floppy Disks
by Peter Reutemann 12 Dec '22

12 Dec '22

'"Linux kernel 6.2 should contain fixes for some problems handling floppy disks," reports the Register, "a move which shows that someone somewhere is still using them." This isn't the only such fix in recent years. As a series of articles on Phoronix details, there has been a slow but steady flow of fixes for the kernel's handling of floppy drives since at least kernel 5.17, as The Register mentioned when it came out.... Back in July 2016, SUSE kernel developer Jiri Kosina submitted a patch. The problem arose because this change broke something else and later got reverted, and so the problem hung around. In July last year, he sent in a new patch that fixed it again for the 5.12 kernel, and was later back-ported to 5.10, an LTS version, and again into kernel 5.15 — another an LTS version, and the one you're running today if you're on the current Ubuntu LTS release, or something built from it such as Linux Mint 21.... Now, in December 2022, a new patch for the forthcoming kernel 6.2 fixes a memory leak that dates back to 5.11 or before.' -- source: https://linux.slashdot.org/story/22/12/11/0711207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Reports Decline In Android Memory Safety Vulnerabilities As Rust Usage Grows
by Peter Reutemann 10 Dec '22

10 Dec '22

'Last year, Google announced Android Open Source Project (AOSP) support for Rust, and today the company provided an update, while highlighting the decline in memory safety vulnerabilities. 9to5Google reports: Google says the "number of memory safety vulnerabilities have dropped considerably over the past few years/releases."; Specifically, the number of annual memory safety vulnerabilities fell from 223 to 85 between 2019 and 2022. They are now 35% of Android's total vulnerabilities versus 76% four years ago. In fact, "2022 is the first year where memory safety vulnerabilities do not represent a majority of Android's vulnerabilities." That count is for "vulnerabilities reported in the Android security bulletin, which includes critical/high severity vulnerabilities reported through our vulnerability rewards program (VRP) and vulnerabilities reported internally." During that period, the amount of new memory-unsafe code entering Android has decreased: "Android 13 is the first Android release where a majority of new code added to the release is in a memory safe language. " Rust makes up 21% of all new native code in Android 13, including the Ultra-wideband (UWB) stack, DNS-over-HTTP3, Keystore2, Android's Virtualization framework (AVF), and "various other components and their open source dependencies." Google considers it significant that there have been "zero memory safety vulnerabilities discovered in Android's Rust code" so far across Android 12 and 13. Google's blog post today also talks about non-memory-safety vulnerabilities, and its future plans: "... We're implementing userspace HALs in Rust. We're adding support for Rust in Trusted Applications. We've migrated VM firmware in the Android Virtualization Framework to Rust. With support for Rust landing in Linux 6.1 we're excited to bring memory-safety to the kernel, starting with kernel drivers.' -- source: https://tech.slashdot.org/story/22/12/01/2124259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Xfce dialog buttons in header
by Peter Reutemann 09 Dec '22

09 Dec '22

Hi everyone Since moving to Xfce, I've been a bit annoyed at my muscle memory as I now have to click on Save/Load/Cancel buttons in the header of save/load dialogs instead of the bottom right. Apparently, I'm not the only dinosaur unhappy about this change, having to move the mouse so far between file format combobox and save button... With the following command, you can move the buttons back to the bottom: xfconf-query -c xsettings -p /Gtk/DialogsUseHeader -s false Found here: https://forums.linuxmint.com/viewtopic.php?p=2039043&sid=a6eeaaa02b60fe9ddd… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
