=> ↺ Enabling Calc support for 16384 columns by default

• Last couple of weeks I have been working on the 16k columns support in Calc. There’s been a lot of work on this already by Noel and others, but so far this has been hidden behind the experimental option, and normally documents open only with the “normal” 1024 columns support. The goal of this work is to finish the 16k support stable enough for it to be the default, so that people who need this many columns can finally get them without any complications.

• As of now all Calc tests pass with the default switched to 16k, and I’ve also dealt with all the known problems from tdf#133764 (minus few rare corner cases that I can deal with later). But I’m pretty sure there are more hidden problems lurking, either crashes because of incorrect bounds checking, or performance problems when some code suddenly deals with 16x more columns. So the next step is to enable this by default in master and collect compl… feedback from guin… testers :).

=> ↺ Use Range Based For Loops – EasyHack

• Because for loops are a powerful tool in C/C++, they are one of the desirable tools when you want to do something repeatedly, or process elements of a data structures. But there many ways to write a for loop. Some forms of it are easier to use, read, write and understand, and some are not. Range based for loops are discussed in this article. They can be good if you know where to use them.

In this blog post, we dive into the actors and mechanics behind digital advertising. If you are curious about the different use cases of digital advertising in embedded devices, please visit the previous blog post in the series.

=> ↺ SUSE statement on “Dirty Pipe” attack | SUSE Communities

• On Monday, March 7th, security researcher Max Kellermann published a new software vulnerability that affect users of the Linux Kernel. The vulnerability, called Dirty Pipe (CVE-2022-0847) , impacts Linux Kernels 5.8 and later, and allows local attackers to overwrite files even if they had only read permissions, allowing for easy privilege escalation.

• The issue is triggered by a combination of two bugs, one bug in Linux Kernels 4.9 and newer and made exploitable by the second bug introduced in Linux Kernel 5.8.

=> ↺ ‘Dirty Pipe’ Linux vulnerability allows an attacker to overwrite data – SiliconANGLE

• A newly revealed vulnerability in the Linux kernel allows an attacker to overwrite data in arbitrary read-only files.

• Detailed today by security researchers Max Kellermann and dubbed “Dirty Pipe,” the vulnerability leads to privilege escalation, since unprivileged processes can inject code into root processes. The vulnerability, officially named CVE-2022-0847, affects Linux Kernel 5.8 and later versions, even on Android devices, but has been fixed in Linux versions 5.16.11, 5.15.25 and 5.10.102.

• Kellermann explains that he found the vulnerability after receiving a support ticket about corrupt files a year ago. The customer complained that the access logs downloaded could not be decompressed. Kellermann confirmed the issue, fixed the issue manually and then closed the ticket, but the issue then occurred again and again.

=> ↺ Serious ‘Dirty Pipe’ Bug Patched in Linux Kernel | Decipher

• A newly disclosed vulnerability in the Linux kernel could allow an attacker to write any data into an arbitrary file and gain elevated privileges. The bug affects the major Linux distributions going back to version 5.8 and Android, but a fix was included in the latest Linux kernel and Android releases in late February. Many vulnerabilities are discovered by researchers who are digging into a particular app or code base, looking for potential issues. But this flaw (CVE-2022-0847) has an unusual origin story. It began in February 2021 when Max Kellermann received a support ticket from a customer of IONOS, the hosting provider where he works. The customer was having an issue decompressing nightly log files, and Kellermann discovered a corrupt file on the log server. He found a cyclic redundancy check (CRC) error in the file, which he fixed and then moved on. The same issue happened several more times in the next couple of months, and Kellermann found each time that the contents of the file looked correct, save for the CRC error.

=> ↺ Linux has been bitten by its most high-severity vulnerability in years | Ars Technica

• Linux has yet another high-severity vulnerability that makes it easy for untrusted users to execute code capable of carrying out a host of malicious actions including installing backdoors, creating unauthorized user accounts, and modifying scripts or binaries used by privileged services or apps.

=> ↺ Linux distributions patch kernel privilege escalation flaw • The Register

• A Linux local privilege escalation flaw dubbed Dirty Pipe has been discovered and disclosed along with proof-of-concept exploit code.

• The flaw, CVE-2022-0847, was introduced in kernel version 5.8 and fixed in versions 5.16.11, 5.15.25 and 5.10.102.

• It can be exploited by a normal logged-in user or a rogue running program to gain root-level privileges; it can also be used by malicious apps to take over vulnerable Android devices. Max Kellermann said he found the programming blunder and reported it to the kernel security team in February, which issued patches within a few days. By now these should be filtering through to affected Linux distros.

• The bug can be abused to add or overwrite data in sensitive read-only files, such as removing the root password from /etc/passwd allowing anyone on the system to get superuser access, or temporarily altering a setuid binary to grant root privileges.

• If you’re running a Linux distro on your computer or use an Android smartphone, you should install the latest updates immediately as a severe security vulnerability has been found and patched in the Linux kernel.

• The vulnerability, tracked as CVE-2022-0847 and dubbed “Dirty Pipe”, was discovered by a software developer named Max Kellerman at the web hosting company IONOS earlier this year.

=> ↺ Researchers Warn of Linux Kernel ‘Dirty Pipe’ Arbitrary File Overwrite Vulnerability

• Linux distributions are in the process of issuing patches to address a newly disclosed security vulnerability in the kernel that could allow an attacker to overwrite arbitrary data into any read-only files and allow for a complete takeover of affected systems.

• Dubbed “Dirty Pipe” (CVE-2022-0847, CVSS score: 7.8) by IONOS software developer Max Kellermann, the flaw “leads to privilege escalation because unprivileged processes can inject code into root processes.”

• Kellerman said the bug was discovered after digging into a support issue raised by one of the customers of the cloud and hosting provider that concerned a case of a “surprising kind of corruption” affecting web server access logs.

=> ↺ Google’s New Tech Can Read Your Body Language—Without Cameras

• WHAT IF YOUR computer decided not to blare out a notification jingle because it noticed you weren’t sitting at your desk? What if your TV saw you leave the couch to answer the front door and paused Netflix automatically, then resumed playback when you sat back down? What if our computers took more social cues from our movements and learned to be more considerate companions?

• It sounds futuristic and perhaps more than a little invasive—a computer watching your every move? But it feels less creepy once you learn that these technologies don’t have to rely on a camera to see where you are and what you’re doing. Instead, they use radar. Google’s Advanced Technology and Products division—better known as ATAP, the department behind oddball projects such as a touch-sensitive denim jacket—has spent the past year exploring how computers can use radar to understand our needs or intentions and then react to us appropriately.

• This is not the first time we’ve seen Google use radar to provide its gadgets with spatial awareness. In 2015, Google unveiled Soli, a sensor that can use radar’s electromagnetic waves to pick up precise gestures and movements. It was first seen in the Google Pixel 4′s ability to detect simple hand gestures so the user could snooze alarms or pause music without having to physically touch the smartphone. More recently, radar sensors were embedded inside the second-generation Nest Hub smart display to detect the movement and breathing patterns of the person sleeping next to it. The device was then able to track the person’s sleep without requiring them to strap on a smartwatch.

=> ↺ ZDNet

• Patent trolls, aka Patent Assertion Entities (PAE)s, have plagued open-source software for ages. Over the years though, other groups have risen up to keep them from stealing from the companies and organizations that actually use patents’ intellectual property (IP). One such group, Unified Patents, an international organization of over 200 businesses, has been winning for the last two years. This is their story to date.

• Unified Patents brings the fight to the trolls. It deters patent trolls from attacking its members by making it too expensive for the troll to win. The group does this by examining troll patents and their activities in various technology sectors (Zones). The United Patents Open Source Software Zone (OSS Zone) is the newest of these Zones.
