Microsoft's Edge Browser for Linux is Now Available for All Users
by Peter Reutemann 03 Nov '21

03 Nov '21

'A year after releasing the first preview build of its Chromium-based Edge browser for Linux, Microsoft is announcing its general availability. From a report: The new release supports a variety of Linux distributions, including Ubuntu, Debian, Fedora and openSUSE. Microsoft announced Linux on Edge's availability milestone during the first day of its Ignite IT Pro conference. As of the release of Edge for Linux to the "stable" (mainstream user) channel, Edge is now available on Windows, Mac, iOS, Android and Linux. As it did when introducing the new Edge on macOS, Microsoft has been positioning Edge on Linux as more of an offering for IT pros and developers who want to test web sites than as a browser for "normal" users on those platforms. However, any user on any supported platform can use the new Edge.' -- source: https://linux.slashdot.org/story/21/11/02/1627250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Trojan Source' Bug Threatens the Security of All Code
by Peter Reutemann 02 Nov '21

02 Nov '21

'"Virtually all compilers -- programs that transform human-readable source code into computer-executable machine code -- are vulnerable to an insidious attack in which an adversary can introduce targeted vulnerabilities into any software without being detected," warns cybersecurity expert Brian Krebs in a new report. An anonymous reader shares an excerpt: Researchers with the University of Cambridge discovered a bug that affects most computer code compilers and many software development environments. At issue is a component of the digital text encoding standard Unicode, which allows computers to exchange information regardless of the language used. Unicode currently defines more than 143,000 characters across 154 different language scripts (in addition to many non-script character sets, such as emojis). Specifically, the weakness involves Unicode's bi-directional or "Bidi" algorithm, which handles displaying text that includes mixed scripts with different display orders, such as Arabic -- which is read right to left -- and English (left to right). But computer systems need to have a deterministic way of resolving conflicting directionality in text. Enter the "Bidi override," which can be used to make left-to-right text read right-to-left, and vice versa. "In some scenarios, the default ordering set by the Bidi Algorithm may not be sufficient," the Cambridge researchers wrote. "For these cases, Bidi override control characters enable switching the display ordering of groups of characters." Bidi overrides enable even single-script characters to be displayed in an order different from their logical encoding. As the researchers point out, this fact has previously been exploited to disguise the file extensions of malware disseminated via email. Here's the problem: Most programming languages let you put these Bidi overrides in comments and strings. This is bad because most programming languages allow comments within which all text -- including control characters -- is ignored by compilers and interpreters. Also, it's bad because most programming languages allow string literals that may contain arbitrary characters, including control characters. "So you can use them in source code that appears innocuous to a human reviewer [that] can actually do something nasty," said Ross Anderson, a professor of computer security at Cambridge and co-author of the research. "That's bad news for projects like Linux and Webkit that accept contributions from random people, subject them to manual review, then incorporate them into critical code. This vulnerability is, as far as I know, the first one to affect almost everything." The research paper, which dubbed the vulnerability "Trojan Source," notes that while both comments and strings will have syntax-specific semantics indicating their start and end, these bounds are not respected by Bidi overrides. [...] Anderson said such an attack could be challenging for a human code reviewer to detect, as the rendered source code looks perfectly acceptable. "If the change in logic is subtle enough to go undetected in subsequent testing, an adversary could introduce targeted vulnerabilities without being detected," he said. Equally concerning is that Bidi override characters persist through the copy-and-paste functions on most modern browsers, editors, and operating systems.' -- source: https://it.slashdot.org/story/21/11/01/2147254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Raspberry Pi Zero 2 W: 5x faster than the original for $5 more
by Peter Reutemann 01 Nov '21

01 Nov '21

'The diminutive Raspberry Pi Zero is getting its first upgrade in nearly five years. Today, Raspberry Pi founder Eben Upton announced the Raspberry Pi Zero 2 W, a new $15 product that puts the processor from the Raspberry Pi 3 into a board the exact same size as the original Zero. The new board swaps the old Zero's 1 GHz single-core ARM11 processor for a quad-core Cortex A53-based Broadcom BCM2710A1 processor, also clocked at 1 GHz—the same processor used in the original Raspberry Pi 3 released back in 2016, albeit clocked slightly lower. This is a substantial increase in power and capability for the Pi Zero, going from one core to four and from 32 bits to 64. Upton said that the performance increase over the original Zero "varies across workloads" but that for multithreaded tasks like those simulated by sysbench, "it is almost exactly five times faster." Heat dissipation is provided by "thick internal copper layers" in the board, which should help prevent thermal throttling without the use of additional fans or heatsinks.' -- source: https://arstechnica.com/gadgets/2021/10/raspberry-pi-zero-2-w-crams-pi-3-pa… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Newly-Discovered 'AbstractEmu' Malware Rooted Android Devices, Evaded Detection
by Peter Reutemann 01 Nov '21

01 Nov '21

'"New Android malware can root infected devices to take complete control and silently tweak system settings, as well as evade detection using code abstraction and anti-emulation checks," reports BleepingComputer. Cybersecurity company Lookout said on its blog that they'd spotted the malware on Google Play "and prominent third-party stores such as the Amazon Appstore and the Samsung Galaxy Store.... To protect Android users, Google promptly removed the app as soon as we notified them of the malware." We named the malware "AbstractEmu" after its use of code abstraction and anti-emulation checks to avoid running while under analysis. A total of 19 related applications were uncovered, seven of which contain rooting functionality, including one on Play that had more than 10,000 downloads... This is a significant discovery because widely-distributed malware with root capabilities have become rare over the past five years. As the Android ecosystem matures there are fewer exploits that affect a large number of devices, making them less useful for threat actors... By using the rooting process to gain privileged access to the Android operating system, the threat actor can silently grant themselves dangerous permissions or install additional malware — steps that would normally require user interaction. Elevated privileges also give the malware access to other apps' sensitive data, something not possible under normal circumstances... AbstractEmu does not have any sophisticated zero-click remote exploit functionality used in advanced APT-style threats, it is activated simply by the user having opened the app. As the malware is disguised as functional apps, most users will likely interact with them shortly after downloading... By rooting the device, the malware is able to silently modify the device in ways that would otherwise require user interaction and access data of other apps on the device. "Apps bundling the malware included password managers and tools like data savers and app launchers," reports BleepingComputer, "all of them providing the functionality they promised to avoid raising suspicions..." Lookout's blog post said they'd spotted people affected by the malware in 17 different countries.' -- source: https://it.slashdot.org/story/21/10/31/1253225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Sprite Fright: Not Your Father’s Blender Open Movie
by Lawrence D'Oliveiro 31 Oct '21

31 Oct '21

The latest short feature from the Blender Studio is now out <https://www.blender.org/>. While past efforts have had the occasional sombre, not to say dark, elements, this one just takes the darkness to the next level. It’s an out-and-out horror story, with overtones of environmental retribution in its plot. Carnage, gore, deaths, and just plain ickiness in full measure, packed into a mere 10 minutes. I just hope the script writer is getting therapy ...

Protonmail Celebrates Swiss Court Victory Exempting it From Telco Data Retention Laws
by Peter Reutemann 28 Oct '21

28 Oct '21

'Encrypted email provider Protonmail has hailed a recent Swiss legal ruling as a "victory for privacy," after winning a lawsuit that sees it exempted from data retention laws in the mountainous realm. From a report: Referring to a previous ruling that exempted instant messaging services from data capture and storage laws, the Protonmail team said this week: "Together, these two rulings are a victory for privacy in Switzerland as many Swiss companies are now exempted from handing over certain user information in response to Swiss legal orders." Switzerland's Federal Administrative Court ruled on October 22 that email providers in Switzerland are not considered telecommunications providers under Swiss law, thereby removing them from the scope of data retention requirements imposed on telcos. The victory comes after controversy over a previous (and not directly related) Swiss court order that forced the company to collect mobile device push notification identifiers from a specified user's account. That user was later arrested by French police, who had asked their Swiss counterparts to obtain the surveillance order. Protonmail chief exec Andy Yen told The Register his business doesn't routinely collect such data on its users.' -- source: https://yro.slashdot.org/story/21/10/27/147224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Core i9 11900K: Five Linux Distros Show Sizable Lead Over Windows 11
by Peter Reutemann 28 Oct '21

28 Oct '21

'Phoronix: Now that Windows 11 has been out as stable and the initial round of updates coming out, I've been running fresh Windows 11 vs. Linux benchmarks for seeing how Microsoft's latest operating system release compares to the fresh batch of Linux distributions. First up is the fresh look at the Windows 11 vs. Linux performance on an Intel Core i9 11900K Rocket Lake system. Microsoft Windows 11 Pro with all stable updates as of 18 October was used for this round of benchmarking on Intel Rocket Lake. The Windows 11 performance was being compared to all of the latest prominent Linux distributions, including: Ubuntu 20.04.3 LTS, Ubuntu 21.10, Arch Linux (latest rolling), Fedora Workstation 35, Clear Linux 35150. All the testing was done on the same Intel Core i9 11900K test system at stock speeds (any frequency differences reported in the system table come down to how the information is exposed by the OS, i.e. base or turbo reporting) with 2 x 16GB DDR4-3200 memory, 2TB Corsair Force MP600 NVMe solid-state drive, and an AMD Radeon VII graphics card. Each operating system was cleanly installed and then run at its OS default settings for seeing how the out-of-the-box OS performance compares for these five Linux distributions to Microsoft Windows 11 Pro. But for the TLDR version... Out of 44 tests run across all six operating systems, Windows 11 had just three wins on this Core i9 11900K system. Meanwhile Intel's own Clear Linux platform easily dominated with coming in first place 75% of the time followed by Fedora Workstation 35 in second place with first place finishes 9% of the time. The geometric mean for all 44 tests showed Linux clearly in front of Windows 11 for this current-generation Intel platform. Ubuntu / Arch / Fedora were about 11% faster overall than Windows 11 Pro on this system. Meanwhile, Clear Linux was about 18% faster than Windows 11 and enjoyed about 5% better performance overall than the other Linux distributions.' -- source: https://linux.slashdot.org/story/21/10/27/1625217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Setback for Nvidia's $54 Billion ARM Bid as EU Regulators Open Probe
by Peter Reutemann 28 Oct '21

28 Oct '21

'Nvidia suffered a setback on Wednesday as EU antitrust regulators opened a full-scale investigation into its $54 billion bid for British chip designer ARM on concerns the deal could lead to higher prices, less choice and reduced innovation. From a report: Britain's competition agency is also probing the deal for the country's most important technology company, warning that it could damage competition and weaken rivals. Reuters reported the European Commission viewed as insufficient concessions offered by the world's biggest maker of graphics and artificial intelligence (AI) chips during its preliminary review. Nvidia has not disclosed what these are but it has previously said it would maintain ARM as a neutral technology supplier to sooth concerns from customers such as Qualcomm, Samsung and Apple. The Commission said it would decide by March 15 whether to clear or block the deal. "Whilst Arm and Nvidia do not directly compete, Arm's IP is an important input in products competing with those of Nvidia, for example in datacentres, automotive and in Internet of Things," EU competition chief Margrethe Vestager said in a statement.' -- source: https://slashdot.org/story/21/10/27/1648229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Android's 12L Feature Drop Aims To Be a Big Improvement for Folding Phones
by Peter Reutemann 28 Oct '21

28 Oct '21

'At this year's Android Dev Summit, Google announced an upcoming update for devices with larger screens, which includes tablets, foldables, and devices that run ChromeOS. From a report: Google is calling the update 12L, and it's supposed to make Android 12 run smoother on big screens. We first heard the possibility of a "12.1" update in late September, and it looks like many of the rumored features are true. 12L optimizes the layout of a device's UI, adjusting the placement of the home screen, lock screen, notifications, Quick Settings, and more. Google notes that any screen 600 density-independent pixels (dp) and above will display a two-column layout that makes use of the entire screen. In the example Google shows, the Quick Settings menu is pushed towards the left side of the screen, while the notifications panel is locked to the right, giving you the ability to access both simultaneously -- all without opening one app and closing another. 12L also introduces a new taskbar that makes it easier for users to quickly switch between different apps. Dragging and dropping an app from the taskbar opens it up in split-screen mode, which Google notes it has enabled for all apps, whether they're resizable or not.' -- source: https://tech.slashdot.org/story/21/10/27/1821200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Trying To Cripple Its Own Open-Source Project
by Lawrence D'Oliveiro 23 Oct '21

23 Oct '21

Microsoft is trying to remove a feature called “Hot Reload” from Dotnet, saying it is something that should only be available through Visual Studio <https://www.theregister.com/2021/10/22/microsoft_net_hot_reload_visual_stud…>. Trouble is, this is the (supposedly) Open-Source version of Dotnet. And you do not take away useful features from Open-Source projects. You can do that to proprietary products, where the users have no choice but to put up with it. As of this writing, the commit that removes the feature has already been merged, but a follow up request to revert that change, while gathering a lot of support, has not been accepted into the official code base yet. As one of the commenters says: “This is the PR that is truly going to decide .NET is really an OSS or not!”. This is just one in a long line of incidents <https://www.theregister.com/2021/10/18/net_foundation_gnome/> casting doubt on the independence of Dotnet as an Open-Source project.

App Telemetry For Developers
by Lawrence D'Oliveiro 23 Oct '21

23 Oct '21

Here’s an interesting idea <https://www.theregister.com/2021/10/22/new_relic_codestream/>: if an app should crash during a production run, it can send telemetry data back to the developer providing some program state and pinpointing exact locations in the source code. This is done using eBPF (Extended Berkeley Packet Filter), which is able to collect information about running applications with minimal impact. You thought packet-filtering was only about managing network activity, but no, it is more useful than that. Yes, there is potential for this sort of thing to be misused, if it is not correctly managed. With great power comes great responsibility etc. By the way, while eBPF may have its roots in the older BPF as found in the BSDs, it is nevertheless a Linux-only technology <https://ebpf.io/>. Though Microsoft is trying to port some parts of it to Windows <https://cloudblogs.microsoft.com/opensource/2021/05/10/making-ebpf-work-on-…>.

GPSD Bug Will Switch Your Time-Keeping Systems To March 2002 This Weekend, Unless You Update
by Peter Reutemann 22 Oct '21

22 Oct '21

'"Apparently a bug in GPSD, the daemon responsible for deriving time from the GPS system, is going to trigger on October 24, 2021, jumping the time back to March of 2002," writes Slashdot reader suutar. "There's a fix that's been committed since August, but of course not everything is up to date." ZDNet's Steven J. Vaughan-Nichols writes: This will be ugly. Or, as Stephen Williams, who uncovered the bug put it, "I have a feeling that there will be some 'interesting moments' in the early morning when a bunch of the world's stratum 1 NTP servers using GPSD take the long strange trip back to 2002." GPSD maintainer Gary E. Miller has acknowledged the problem, and a fix has been made to the code. To be exact, the fix is in August 2021's GPSD 3.23 release. So, what's the problem if the fix is already in? Well, there are two problems. First, it won't be backported to previous releases. If you're still using an older version, you may be out of luck. Second, as Miller observed, not all distros "pick up GPSD updates or upstream their patches. [This] is a very sore spot with me." So, just because your operating system is up to date does not mean that it will have the necessary GPSD fix. Miller suggests that you check it and do it yourself: "I [am] gonna fall back on Greg K_H's dictum: All users must update." Oh, wondering what the mysterious root cause of all this commotion GPS Week Rollover? It's a legacy GPS problem. The GPS signal GPS week number uses a 10-bit code with a maximum value of 1,023. This means every 19.7 years; the GPS week number rolls over to zero. Or, as Miller noted, "This code is a 1024 week time warp waiting to happen." So, check your systems now for this problem. And, if, like most of us, you're relying on someone upstream from you for the correct time, check with them to make sure they've taken care of this forthcoming trouble.' -- source: https://it.slashdot.org/story/21/10/21/2053248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Versus The Chip Foundries
by Lawrence D'Oliveiro 21 Oct '21

21 Oct '21

Nice backgrounder <https://arstechnica.com/tech-policy/2021/10/intel-slipped-and-its-future-no…> on how Intel (and American chipmakers generally) slipped from their leadership position by overlooking an important new business: manufacturing chips according to other people’s designs. We’ve all heard of Taiwan-based TSMC, which is the world leader in this area; when it was founded way back in 1987 (with help from the Taiwanese Government and from Philips), none of the US companies would take such an idea seriously. They didn’t think it would amount to a very profitable business, and anyway they wanted to control their own Intellectual Property. Plus, a company that made chips both for its own internal businesses and for others could never be seen to be entirely above accusations of conflict of interest. Note also the role played by Carver Mead, basically the father of the whole concept of RISC. He wanted a place to go to, where his students (and those of other teachers) could get their designs turned into actual working chips. He had special personal connections with Intel to get access to their fabs, but he knew others were not so lucky. So he played an influential part in getting TSMC started.

Brave Removes Google as its Default Search Engine
by Peter Reutemann 20 Oct '21

20 Oct '21

'As Paul Thurrott reports, Brave is removing Google Search as its default search engine. From the report: Going forward, the Brave web browser will default to Brave Search. "Brave Search has grown significantly since its release last June, with nearly 80 million queries per month," Brave CEO and co-founder Brendan Eich says. "Our users are pleased with the comprehensive privacy solution that Brave Search provides against Big Tech by being integrated into our browser. As we know from experience in many browsers, the default setting is crucial for adoption, and Brave Search has reached the quality and critical mass needed to become our default search option, and to offer our users a seamless privacy-by-default online experience." Brave Search is built on top of an independent index, and doesn't track users, their searches, or their clicks, the firm says. And starting with Brave 1.3 on desktop and Android, and Brave 1.32 on iOS, it will be the default search engine in the browser, instead of Google, in the United States, Canada, and the United Kingdom. It is also replacing Qwant in France and DuckDuckGo in Germany, and Brave says that more locales will be added in the next several months. Existing users can keep their chosen search engine default, of course, and new users who prefer other search engines can configure as needed. Brave Search doesn't display ads today, but the free version of the service will soon be ad-supported. An ad-free Premium version is coming "in the near future," Brave says. Along with this search engine news, Brave announced the Web Discovery Project (WDP), "which it describes as a privacy-preserving system for users to anonymously contribute data to improve Brave Search results," writes Thurrott. "The WDP is an opt-in feature that protects user privacy and anonymity by ensuring that contributed data is not linked to individuals, their devices, or any set of users." It has a GitHub repo available to help you learn more about this system.' -- source: https://tech.slashdot.org/story/21/10/19/2121251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

PowerPC Fork of Firefox Reaches End of the Road
by Peter Reutemann 15 Oct '21

15 Oct '21

'Ars Technica: It has been well over a decade since PowerPC Macs roamed the earth -- so long that the Intel Macs that replaced them are themselves being replaced by something else. But to this day, there's a small community of people still developing software for PowerPC Macs and Mac OS 9. One of those projects was TenFourFox, a fork of the Firefox browser for G3, G4, and G5-based PowerPC Macs running Mac OS X 10.4 or 10.5. Maintained primarily by Cameron Kaiser, the TenFourFox project sprang up in late 2010 after Mozilla pulled PowerPC support from Firefox 4 during its development. And amazingly, the browser has continued to trundle on ever since. But continuing to backport Firefox features to aging, stuck-in-time PowerPC processors only got more difficult as time went on. And in March of this year, Kaiser announced that TenFourFox updates would be ending after over a decade of development. The final planned release of TenFourFox was earlier this month. Kaiser's full post is long, but it's worth a read for vintage-computer enthusiasts or anyone who works on software -- Kaiser expresses frustration with the realities of developing and supporting a niche app, but he also highlights TenFourFox's impressive technical achievements and ruminates on the nature of the modern Internet and open source software development [...]. Kaiser doesn't intend to fully halt work on the browser, but he is downshifting it into what he calls "hobby mode." He will continue to backport security patches from newer ESR releases of Firefox and post them to the TenFourFox Github page, but anyone who wants to use these will need to build the app themselves. Kaiser also won't commit to providing support for these additions or providing them on any kind of schedule. Other developers are also welcome to continue to release TenFourFox builds on their own.

Modular Framework Laptop Gets Marketplace For All Those Modules
by Peter Reutemann 15 Oct '21

15 Oct '21

'Framework, makers of the modular 13.5-inch Framework laptop that's designed to be easily repaired and upgraded, has launched a dedicated marketplace filled with replacement parts and upgrades for its portable computer. The Verge reports: Writing in a blog post, the company said the marketplace is currently focused on replacement parts and expansion cards, but that it hopes to add more customization modules like additional language keyboards later this year, as well as third-party and community developed modules in 2022. The marketplace already includes a range of expansion cards for the laptop, which are designed to slot into its four modular compartments to add everything from extra storage to features like MicroSD card slots or more USB ports. There's also user upgradeable RAM and storage for sale. But the store is clearly a work in progress, and lists a host of other items like replacement CPU-equipped mainboards, keyboards, and spare parts like batteries and displays as "coming soon."

Canonical Releases Ubuntu Linux 21.10 Impish Indri
by Peter Reutemann 15 Oct '21

15 Oct '21

'Following a brief beta-testing period, Ubuntu 21.10 has finally become available to download in the "final" stable form. BetaNews: Code-named "Impish Indri," this version of Ubuntu is not a Long Term Support (LTS) version, so it is only supported for nine months. Ubuntu 21.10 features Linux kernel 5.13 and a Snap variant of the Mozilla Firefox browser. "Ubuntu 21.10 brings the all-new PHP 8 and GCC 11 including full support for static analysis, greatly improving everyday developer security awareness in low-level programming. With Gnome 40 desktop users gain dynamic workspaces and touchpad gestures. The new Firefox snap, published by Mozilla, improves security and guarantees access to both the latest and the extended support release versions of the browser. The exact same versions of the browser are available on multiple different versions of Ubuntu, simplifying enterprise developer platform management," says Canonical.' -- source: https://linux.slashdot.org/story/21/10/14/2013235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

LibreOffice, OpenOffice Bug Allows Hackers To Spoof Signed Docs
by Peter Reutemann 12 Oct '21

12 Oct '21

'LibreOffice and OpenOffice have pushed updates to address a vulnerability that makes it possible for an attacker to manipulate documents to appear as signed by a trusted source. Although the severity of the flaw is classified as moderate, the implications could be dire. BleepingComputer reports: The discovery of the flaw, which is tracked as CVE-2021-41832 for OpenOffice, was the work of four researchers at the Ruhr University Bochum. The same flaw impacts LibreOffice, which is a fork of OpenOffice spawned from the main project over a decade ago, and for their project is tracked as CVE-2021-25635. If you're using either of the open-source office suites, you're advised to upgrade to the latest available version immediately. For OpenOffice, that would be 4.1.10 and later, and for LibreOffice, 7.0.5 or 7.1.1 and later. Since neither of these two applications offer auto-updating, you should do it manually by downloading the latest version from the respective download centers -- LibreOffice, OpenOffice. If you're using Linux and the aforementioned versions aren't available on your distribution's package manager yet, you are advised to download the "deb", or "rpm" package from the Download center or build LibreOffice from source. If updating to the latest version is not possible for any reason, you can always opt to completely disable the macro features on your office suite, or avoid trusting any documents containing macros.
