Not Just Apple: GnuTLS Bug Means Security Flaw For Major Linux Distros 144

Posted by timothy
from the holes-to-plug dept.
According to an article at Ars Technica, a major security bug faces Linux users, akin to the one recently found in Apple's iOS (and which Apple has since fixed). Says the article:"The bug is the result of commands in a section of the GnuTLS code that verify the authenticity of TLS certificates, which are often known simply as X509 certificates. The coding error, which may have been present in the code since 2005, causes critical verification checks to be terminated, drawing ironic parallels to the extremely critical 'goto fail' flaw that for months put users of Apple's iOS and OS X operating systems at risk of surreptitious eavesdropping attacks. Apple developers have since patched the bug." And while Apple can readily fix a bug in its own software, at least for users who keep up on patches, "Linux" refers to a broad range of systems and vendors, rather than a single company, and the affected systems include some of the biggest names in the Linux world, like Red Hat, Debian, and Ubuntu.

Linux Developers Consider On-Screen QR Codes For Kernel Panics 175

Posted by timothy
from the take-a-picture-it'll-last-longer dept.
An anonymous reader writes "Linux kernel developers are currently evaluating the possibility of using QR codes to display kernel oops/panic messages. Right now a lot of text is dumped to the screen when a kernel oops occurs, most of which isn't easily archivable by normal Linux end-users. With QR codes as Linux oops messages, a smart-phone could capture the display and either report the error string or redirect them to an error page on Kernel.org. The idea of using QR codes within the Linux kernel is still being discussed by upstream developers."

Intel Releases $99 'MinnowBoard Max,' an Open-Source Single-Board Computer 97

Posted by timothy
from the embed-and-deploy dept.
A few months back, we posted a video interview with some of the folks behind the Linux-friendly, x86-based MinnowBoard. TechCrunch reports the release of a more powerful version of the same all-in-one computer, now with a 1.91GHz Atom E3845 processor. According to the linked article, "The board's schematics are also available for download and the Intel graphics chipset has open-source drivers so hackers can have their way with the board. While it doesn’t compete directly with the Raspberry Pi – the Pi is more an educational tool and already has a robust ecosystem – it is a way for DIYers to mess around in x86 architected systems as well as save a bit of cash. The system uses break-out boards called Lures to expand functionality."

Ask Slashdot: User-Friendly Firewall For a Brand-New Linux User? 187

Posted by timothy
from the perfect-security-on-the-way dept.
An anonymous reader writes "I am a new Linux user; I'm on 2nd day now. Currently I am trying out Ubuntu, but that could change. I am looking for a user friendly firewall that I can set up that lets me do these things:1) set up a default deny rule 2) carve out exceptions for these programs: browser, email client, chat client, yum and/or apt. 3) carve out exceptions to the exceptions in requirement 2 — i.e. I want to be able to then block off IPs and IP ranges known to be used by malware, marketers, etc., and all protocols which aren't needed for requirement 2. It also needs to have good enough documentation that a beginner like me can figure it out. Previously, I had done all of the above in AVG Firewall on Windows, and it was very easy to do. So far, I have tried these things:1) IPTABLES — it looked really easy to screw it up and then not notice that it's screwed up and/or not be able to fix it even if I did notice, so I tried other things at that point... 2) searched the internet and found various free firewalls such as Firestarter, GUFW, etc., which I weren't able to make meet my requirements. Can someone either point me to a firewall that meets my needs or else give me some hints on how to make firestarter or GUFW do what I need?"

from the wardriving-in-style dept.
New submitter FikseGTS (3604833) writes "A Tesla Model S owner located a 4 pin connector on the left side of the Tesla Model S dashboard that turns out to be a disguised ethernet networking port. After crafting his owns patch cable to connect with the Tesla's port, a networking connection was established between the Tesla Model S and a laptop computer. The Model S is running a 100 Mbps, full duplex ethernet network and 3 devices were found with assigned IP addresses in the 192.168.90.0 subnet. Some ports and services that were open on the devices were 22 (SSH), 23 (telnet),53 (open domain), 80 (HTTP), 111 (rpcbind), 2049 (NFS), 6000 (X11). Port 80 was serving up a web page with the image or media of the current song being played. The operating system is modified version of Ubuntu using an ext3 filesystem. Using X11 it also appears that someone was able to somewhat run Firefox on both of the Model S screens. Is a jailbroken Tesla Model S on the way?" Some more details on this front would be appreciated, for anyone who has a Tesla they'd like to explore.

Linus Torvalds Suspends Key Linux Developer 641

Posted by Soulskill
from the arguing-about-penguins dept.
alphadogg writes: "An argument between developers of some of the most basic parts of Linux turned heated this week, resulting in a prominent Red Hat employee and code contributor being banned from working on the Linux kernel. Kay Sievers, a well-known open-source software engineer, is a key developer of systemd, a system management framework for Linux-based operating systems. Systemd is currently used by several prominent Linux distributions, including two of the most prominent enterprise distros, Red Hat and SUSE. It was recently announced that Ubuntu would adopt systemd in future versions as well. Sievers was banned by kernel maintainer Linus Torvalds on Wednesday for failing to address an issue that caused systemd to interact with the Linux kernel in negative ways."

Intel Upgrades MinnowBoard: Baytrail CPU, Nearly Halves Price To $99 92

Posted by Unknown Lamer
from the moar-power dept.
DeviceGuru (1136715) writes "Intel and CircuitCo have revealed a smaller, faster, 2nd-gen MinnowBoard open SBC based on an Atom E3800 SoC and supported by both Android 4.4 and various standard Linux OSes. The MinnowBoard Max, which will ship in Q3 starting at $99, blows past the original MinnowBoard (Slashdot video) on price, performance, and energy consumption. The 3.9 x 2.9-inch Max's $99 starting price includes a 64-bit 1.46GHz Intel Atom E3815 (Bay Trail-T) CPU, 1GB RAM and 8GB SPI flash, and coastline ports for MicroSD, Micro-HDMI, GbE, dual USB, and SATA. Unlike the original MinnowBoard, the Max provides two expansion connectors: a low-speed header, with signals similar to the Arduino's Shield connector; and a high-speed connector, which can support mSATA and mini-PCIe sockets on expansion modules, among other interfaces. Although the Max's design supports CPUs up to Intel's quad-core 1.91GHz (10W TDP) E3845, only two choices shown initially at MinnowBoard.org, with the higher-end $129 model stepping up to a 1.33GHz dual-core E3825 plus 2GB RAM.."

oVirt 3.4 Means Management, VMs Can Live On the Same Machine 51

darthcamaro (735685) writes "Red Hat's open source oVirt project hit a major milestone this week with the release of version 3.4. It's got improved storage handling so users can mix and match different resource types, though the big new feature is one that seems painfully obvious. For the first time oVirt users can have the oVirt Manager and oVirt VMs on the same physical machine. 'So, typically, customers deployed the oVirt engine on a physical machine or on a virtual machine that wasn't managed or monitored,' Scott Herold, principal product manager for Red Hat Enterprise Virtualization said. 'The oVirt 3.4 release adds the ability for oVirt to self-host its engine, including monitoring and recovery of the virtual machine.'" (Wikipedia describes oVirt as "a free platform virtualization management web application community project.")

Ask Slashdot: How To Handle Unfixed Linux Accessibility Bugs? 266

Posted by timothy
from the linux-on-the-desktop dept.
dotancohen (1015143) writes "It is commonly said that open source software is preferable because if you need something changed, you can change it yourself. Well, I am not an Xorg developer and I cannot maintain a separate Xorg fork. Xorg version 1.13.1 introduced a bug which breaks the "Sticky Keys" accessibility option. Thus, handicapped users who rely on the feature cannot use Xorg-based systems with the affected versions and are stuck on older software versions. Though all pre-bug Linux distros are soon scheduled for retirement, there seems to be no fix in sight. Should disabled users stick with outdated, vulnerable, and unsupported Linux distros or should we move to OS-X / Windows?

The prospect of changing my OS, applications, and practices due to such an ostensibly small issue is frightening. Note that we are not discussing 'I don't like change' but rather 'this unintentional change is incompatible with my physical disability.' Thus this is not a case of every change breaks someone's workflow."

KDE developers, who do have long experience with Qt (something Canonical is moving towards for its mobile ambitions), have refuted Bob's claims and said that display server does matter."

Ask Slashdot: Moving From Tech Support To Development? 133

An anonymous reader writes "My eastern European tech-support job will be outsourced in 6 months to a nearby country. I do not wish to move, having relationship and roots here, and as such I stand at a crossroads. I could take my current hobby more seriously and focus on Java development. I have no degree, no professional experience in the field, and as such, I do not hold much market value for an employer. However, I find joy in the creative problem solving that programming provides. Seeing the cogs finally turn after hours invested gives me pleasures my mundane work could never do. The second option is Linux system administration with a specialization in VMware virtualisation. I have no certificates, but I have been around enterprise environments (with limited support of VMware) for 21 months now, so at the end of my contract with 27 months under my belt, I could convince a company to hire me based on willingness to learn and improve. All the literature is freely available, and I've been playing with VDIs in Debian already.

My situation is as follows: all living expenses except food, luxuries and entertainment is covered by the wage of my girlfriend. That would leave me in a situation where we would be financially alright, but not well off, if I were to earn significantly less than I do now. I am convinced that I would be able to make it in system administration, however, that is not my passion. I am at an age where children are not a concern, and risks seem to be, at first sight, easier to take. I would like to hear the opinion and experience of fellow readers who might have been in a similar situation."

AMD Develops New Linux Open-Source Driver Model 142

Posted by timothy
from the winds-of-change dept.
An anonymous reader writes "AMD privately shared with Phoronix during GDC2014 that they're developing a new Linux driver model. While there will still be an open (Gallium3D) and closed-source (Catalyst) driver, the Catalyst driver will be much smaller. AMD developers are trying to isolate the closed-source portion of the driver to just user-space while the kernel driver that's in the mainline Linux kernel would also be used by Catalyst. It's not clear if this will ultimately work but they hope it will for reducing code duplication, eliminating fragmentation with different kernels, and allowing open and closed-source driver developers to better collaborate over the AMD Radeon Linux kernel driver."

Speedy Attack Targets Web Servers With Outdated Linux Kernels 93

Posted by Soulskill
from the update-your-junk dept.
alphadogg writes "Web servers running a long-outdated version of the Linux kernel were attacked with dramatic speed over two days last week, according to Cisco Systems. All the affected servers were running the 2.6 version, first released in December 2003. 'When attackers discover a vulnerability in the system, they can exploit it at their whim without fear of it being remedied,' Cisco said. After the Web server has been compromised, the attackers slip in a line of JavaScript to other JavaScript files within the website. That code bounces the website's visitors to a second compromised host. 'The two-stage process allows attackers to serve up a variety of malicious content to the visitor,' according to Cisco."

Linux May Succeed Windows XP As OS of Choice For ATMs 367

Posted by Soulskill
from the cash-from-a-penguin dept.
Dega704 sends this news from ComputerWorld: "Some financial services companies are looking to migrate their ATM fleets from Windows to Linux in a bid to have better control over hardware and software upgrade cycles. Pushing them in that direction apparently is Microsoft's decision to end support for Windows XP on April 8, said David Tente, executive director, USA, of the ATM Industry Association. 'There is some heartburn in the industry' over Microsoft's end-of-support decision, Tente said. ATM operators would like to be able to synchronize their hardware and software upgrade cycles. But that's hard to do with Microsoft dictating the software upgrade timetable. As a result, 'some are looking at the possibility of using a non-Microsoft operating system to synch up their hardware and software upgrades,' Tente said."

Debian Considering Long Term Support for Squeeze 46

Posted by Unknown Lamer
from the thank-gnu dept.
Via Bits from Debian, comes news that the security team is considering adding a Long Term Support suite for Squeeze (Debian 6) after Jessie (Debian 8) is released sometime next year. From the mailing list post: "At the moment it seems likely that an extended security support timespan for squeeze is possible. The plan is to go ahead, sort out the details as as it happens, and see how this works out and whether it is going to be continued with wheezy. The rough draft is that updates will be delivered via a separate suite (e.g. squeeze-lts), where everyone in the Debian keyring can upload in order to minimise bottlenecks and allow contributions by all interested parties. Some packages will be exempted upfront due to their volatile nature (e.g. some web applications) and others might be expected to see important changes. The LTS suite will be limited to amd64 and i386. The exact procedures will be sorted out soon and announced in a separate mail. ... It needs to be pointed out that for this effort to be sustainable actual contributions by interested parties are required. squeeze-lts is not something that will magically fall from the sky. If you're dependent/interested in extended security support you should make an effort to contribute." If successful, the LTS idea would possibly be carried over to Wheezy. With all of the changes coming in Jessie and its aggressive release schedule, this sysadmin really likes the idea of having a bit more breathing room for updating infrastructure between releases. The email also contains a bunch of other info on changes coming to the security process.

In related news, the Debian Installer team announced the first alpha of debian-installer for Jessie. Just the installer, not the distro as a whole (Jessie will be frozen in November). XFCE remains the default desktop, ia64 was kicked out of the archive, and a few new ARM variants are supported.

GNU C Library Alternative Musl Libc Hits 1.0 Milestone 134

Posted by Unknown Lamer
from the pry-glibc-from-my-cold-dead-ld.so dept.
New submitter dalias (1978986) writes "The musl libc project has released version 1.0, the result of three years of development and testing. Musl is a lightweight, fast, simple, MIT-licensed, correctness-oriented alternative to the GNU C library (glibc), uClibc, or Android's Bionic. At this point musl provides all mandatory C99 and POSIX interfaces (plus a lot of widely-used extensions), and well over 5000 packages are known to build successfully against musl.

Several options are available for trying musl. Compiler toolchains are available from the musl-cross project, and several new musl-based Linux distributions are already available (Sabotage and Snowflake, among others). Some well-established distributions including OpenWRT and Gentoo are in the process of adding musl-based variants, and others (Aboriginal, Alpine, Bedrock, Dragora) are adopting musl as their default libc."
The What's New file contains release notes (you have to scroll to the bottom). There's also a handy chart comparing muscl to other libc implementations: it looks like musl is a better bet than dietlibc and uclibc for embedded use.

No amount of careful planning will ever replace dumb luck.
