'Millions of WordPress sites have received a forced update over the past day to fix a critical vulnerability in a plugin called UpdraftPlus. The mandatory patch came at the request of UpdraftPlus developers because of the severity of the vulnerability, which allows untrusted subscribers, customers, and others to download the site’s private database as long as they have an account on the vulnerable site. Databases frequently include sensitive information about customers or the site’s security settings, leaving millions of sites susceptible to serious data breaches that spill passwords, user names, IP addresses, and more.' -- source: https://arstechnica.com/information-technology/2022/02/millions-of-wordpres… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Developers Patch Bugs Faster Than Microsoft, Apple, and Google, Study Shows
by Peter Reutemann 21 Feb '22

21 Feb '22

'Linux programmers fixed bugs faster than anyone — in an average of just 25 days (improving from 32 days in 2019 to just 15 in 2021). That's the conclusion of Google's "Project Zero" security research team, which studied the speed of bug-fixing from January 2019 to December 2021. ZDNet reports that Linux's competition "didn't do nearly as well." For instance, Apple, 69 days; Google, 44 days; and Mozilla, 46 days. Coming in at the bottom was Microsoft, 83 days, and Oracle, albeit with only a handful of security problems, with 109 days. By Project Zero's count, others, which included primarily open-source organizations and companies such as Apache, Canonical, Github, and Kubernetes, came in with a respectable 44 days. Generally, everyone's getting faster at fixing security bugs. In 2021, vendors took an average of 52 days to fix reported security vulnerabilities. Only three years ago the average was 80 days. In particular, the Project Zero crew noted that Microsoft, Apple, and Linux all significantly reduced their time to fix over the last two years. As for mobile operating systems, Apple iOS with an average of 70 days is a nose better than Android with its 72 days. On the other hand, iOS had far more bugs, 72, than Android with its 10 problems. Browsers problems are also being fixed at a faster pace. Chrome fixed its 40 problems with an average of just under 30 days. Mozilla Firefox, with a mere 8 security holes, patched them in an average of 37.8 days. Webkit, Apple's web browser engine, which is primarily used by Safari, has a much poorer track record. Webkit's programmers take an average of over 72 days to fix bugs.' -- source: https://linux.slashdot.org/story/22/02/20/1915222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why I Don’t Like Checking Version Numbers
by Lawrence D'Oliveiro 18 Feb '22

18 Feb '22

Some major web browsers will soon be hitting version 100. The rollover to a 3-digit version number is going to trigger a repeat of what happened when version numbers rolled from 9 to 10 -- some sites turned out to have buggy version checking based simplistically on strings rather than numeric values, and misbehave <https://www.theregister.com/2022/02/17/browsers_version_100_websites_bug/>. As a matter of habit, I have long been reluctant to condition behaviour in my own code based on writing code to look up version numbers of things. I prefer to include some kind of check that more directly determines the existence of relevant functionality.

Ransomware-As-A-Service
by Lawrence D'Oliveiro 10 Feb '22

10 Feb '22

From <https://www.theregister.com/2022/02/09/uk_us_au_ransomware_warning/>: Ransomware attacks are proliferating as criminals turn to gangs providing turnkey post-compromise services, Britain's National Cyber Security Centre (NCSC) has warned. So, ransomware has become so routine, it has spawned specialists who will take care of many of the technical details for you. For a fee, of course. I think “turnkey post-compromise services” shall be my phrase of the week ...

Listening To The Radio Killed My Car Stereo!
by Lawrence D'Oliveiro 10 Feb '22

10 Feb '22

From <https://arstechnica.com/cars/2022/02/radio-station-snafu-in-seattle-bricks-…>: ... the problem began on January 30 and afflicted Mazdas from model years 2014 to 2017 when the cars were tuned to the local NPR station, KUOW 94.9. At some point during the day's broadcast, a signal from KUOW caused the Mazdas' infotainment systems to crash—the screens died and the radios were stuck on 94.9 FM. The problem was image files† in the HD radio stream that the infotainment system didn’t know how to decode (they were lacking filename extensions). So it crashed. But the files were still in its cache on reboot, so it tried to decode them again. And crashed again. And it appears, there is no way to get rid of those files or reset the system to a safe state without major hardware surgery. And a replacement unit costs USD1,500 -- if you can get one. Luckily, Mazda has advised that it knows about the problem, and will replace the affected units free of charge -- once supplies are available. †Radio with pictures? Who knew?

'System76's latest Linux laptop combines one of AMD's most powerful 5000 series mobile CPUs with Nvidia's mid-range RTX 3060. Configurable to up to $3,442, the Kudu targets Linux users who have a lot of work to do, while quietly nodding at those who like to play games every now and then, too. The 15.6-inch Kudu is the second-priciest offering in System76's laptop lineup. It comes with an octa-core AMD Ryzen 9 5900HX, which has a base clock speed of 3.3 GHz and a boost of up to 4.6 GHz.' -- source: https://arstechnica.com/gadgets/2022/02/system76-linux-laptop-unites-amd-nv… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla is Shutting Down Its VR Web Browser, Firefox Reality
by Peter Reutemann 04 Feb '22

04 Feb '22

'A top VR web browser is closing down. Today, Mozilla announced it's shutting down its Firefox Reality browser -- the four-year-old browser built for use in virtual reality environments. The technology had allowed users to access the web from within their VR headset, doing things like visiting URLs, performing searches, and browsing both the 2D and 3D internet using your VR hand controllers, instead of a mouse. >From a report: Firefox Reality first launched in fall 2018 and has been available on Viveport, Oculus, Pico, and Hololens platforms through their various app stores. While capable of surfing the 2D web, the expectation was that users would largely use the new technology to browse and interact with the web's 3D content, like 360-degree panoramic images and videos, 3D models, and WebVR games, for example. But in an announcement published today, Mozilla says the browser will be removed from the stores where it's been available for download in the "coming weeks." Mozilla is instead directing users who still want to utilize a web browser in VR to Igalia's upcoming open-source browser, Wolvic, which is based on Firefox Reality's source code. This browser will be available for download starting next week, so users won't have to go without -- they'll just have to make the switch.' -- source: https://tech.slashdot.org/story/22/02/03/1653218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

by Peter Reutemann 04 Feb '22

04 Feb '22

'Slackware, the oldest actively maintained Linux distribution, released version 15.0 yesterday after a long release cycle that goes all the way back to 2016 where the last version (14.2) was released. According to the release notes, the whole spirit of this release is: "Keep it familiar, but make it modern." Among the news, this release offers kernel 5.15.19, PAM, PipeWire and PulseAudio, Wayland and X11 graphical systems, and Rust and Python 3. As graphical environments, both Xfce 4.16 and the latest Plasma 5 (Plasma 5.23.5, Frameworks 5.90, KDE apps 21.12 running under Qt 5.15.3) are available, with Cinnamon and Mate also available from third parties. The main compilers are gcc-11.2 and llvm 13.0. The default browser is Firefox 91.5esr, with Chromium available as a third-party repository. And... no systemd at all. Slackware can be downloaded from a variety of mirrors. BitTorrent downloads are going to be available too. I've used Slackware for 20 years and it's always impressed me with its stability and speed. I encourage everyone interested to try it.' -- source: https://linux.slashdot.org/story/22/02/04/027213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Says Windows May Need Up To 8 Hours of Online Time To Update
by Peter Reutemann 03 Feb '22

03 Feb '22

'According to a post on the Microsoft IT Pro Blog, Windows computers will need at least eight hours of online time to obtain and install the latest OS updates successfully. Tom's Hardware reports: Another revelation in the post is that Microsoft tracks how long PCs are connected to Windows Update, calling the statistics "Update Connectivity." The data is available to IT managers in the InTune app, a component of the Endpoint management suite. The post details Microsoft's attempts to figure out why some Windows devices aren't getting the latest quality and feature updates, and discovered that two hours of continuous connectivity was required to get updates. It then took six hours after the release of the patch for a machine to update itself reliably. Microsoft's figures show that 50 percent of Windows devices left behind by Windows Update and running a build of Windows 10 that's no longer serviced do not spend enough time connected to have the patches downloaded and installed in the background. This figure drops to 25 percent for customers using a serviced build of the operating system that lags behind in security updates by 60 days or more. The goods news, as noted by Tom's Hardware, is that "Windows 11 updates are smaller than their Windows 10 counterparts due to improved compression [and] new Microsoft Graph APIs," which should help speed up the update process.' -- source: https://tech.slashdot.org/story/22/02/01/2056211 Bloatware? I can download/install full Linux distros in less time (and updates don't take that long either, not even a full version upgrade!).

Insights Into WSL 1.0
by Lawrence D'Oliveiro 03 Feb '22

03 Feb '22

You may remember that Microsoft’s initial attempt at “Windows Services for Linux”, WSL 1.0 (or maybe just plain “WSL”), involved emulating Linux APIs on top of the Windows kernel. This was later scrapped in favour of the current WSL 2.0, which runs an actual Linux kernel, virtualized. Clearly, Microsoft found it problematic trying to keep things compatible with the native Linux kernel, and decided it was simpler to just run the real article. This report <https://www.theregister.com/2022/02/02/oracle_linux_microsoft/> links in passing to an interesting blog post <https://jmmv.dev/2020/11/wsl-lost-potential.html> covering some of the technicalities of how WSL 1.0 was implemented. Windows NT has, or had, the notion of different “environment subsystems” or “personalities” implemented in layers on top of the core kernel; in fact, Win32 is (or was) just one of these “personalities”, with the original POSIX layer being another. That blog post says that WSL1 was implemented as just such a “personality”. And if that had not been scrapped, it would have made some interesting kinds of integration across Windows and Linux processes possible. However, a reader comment to the original article <https://forums.theregister.com/forum/all/2022/02/02/oracle_linux_microsoft/…>, claiming to come from a former “PM” (“Product Manager”?) for WSL, emphatically declares ... WSL is not an NT kernel "personality" and is in no way related to NT's POSIX subsystem. Not even slightly. They are entirely different implementations of different things and share zero architecture and implementation details. This reinforces an impression I’ve had, that much of the modularity of the original Windows NT architecture has decayed away over the years, sacrificed by Microsoft to marketing exigencies. And that includes the whole “environment subsystem” concept. So WSL1 was actually less modular than it might have appeared to begin with, and that would have added to the support headaches.
