Hi all,

I'd like to announce the linux-stable security tree project. The purpose
is to create a derivative tree from the regular stable tree that would
contain only commits that fix security vulnerabilities.

  • Cybersecurity education isn't good, nobody is shocked

    There was a news story published last week about the almost total lack of cybersecurity attention in undergraduate education. Most people in the security industry won't be surprised by this. In the majority of cases when the security folks have to talk to developers, there is a clear lack of understanding about security.

  • Making it easier to deploy TPMTOTP on non-EFI systems

    On EFI systems you can handle this by sticking the secret in an EFI variable (there's some special-casing in the code to deal with the additional metadata on the front of things you read out of efivarfs). But that's not terribly useful if you're not on an EFI system. Thankfully, there's a way around this. TPMs have a small quantity of nvram built into them, so we can stick the secret there. If you pass the -n argument to sealdata, that'll happen. The unseal apps will attempt to pull the secret out of nvram before falling back to looking for a file, so things should just magically work.

  • 6 steps to calculate ROI for an open hardware project

    Free and open source software advocates have courageously blazed a trail that is now being followed by those interested in open source for physical objects. It's called free and open source hardware (FOSH), and we're seeing an exponential rise in the number of free designs for hardware released under opensource licenses, Creative Commons licenses,or placed in the public domain.

Linux Mint security – 28 days later

Linux
Security

Linux Mint has suffered a reputation damage, which has led to doubts and questions being raised in the community. Valid questions, because you don’t want any private, confidential data to be transmitted to a third party without your knowledge and consent. So you may want to check if Mint is clean, and whether it can be used safely. This article outlines the technical methods.

However, you should also not forget that this is not the first, nor the last hack of a website related to a distro project. All the big names have had similar issues in the past. Moreover, obscurity does not guarantee security. If you’ve never thought about this topic before Feb 20, then you really should not be focusing too much energy on it now. Because all the other times you downloaded packages and updates your system, there could have been a breach somewhere, but since you were not aware of it, you did not do anything about it. Now you are aware, but it does not change the reality, only your perception. You may want to double-check everything now, it’s a natural reaction, but it’s not really grounded in any hard, solid facts. If anything, the hack only helps put more security highlight on the distros and their management, so they should now be more secure than ever before.

There.

  • OSVDB Shuts Down, Firefox Add-ons Unsafe & More…

    Speaking of vulnerabilities: We lost an open source security asset this week. On Tuesday we received word that OSVDB, or the Open Sourced Vulnerability Database project, an organization that’s cataloged computer security flaws since 2002, is closing up shop. The news came by way of an OSVDB blog that said, “We are not looking for anyone to offer assistance at this point, and it [the database] will not be resurrected in its previous form.” As for why the database is being shut down, the post went on to somewhat cryptically explain, “The industry simply did not want to contribute and support such an effort.” A good analysis of the details by Jon Gold was published Thursday on Network World.

  • Nation-wide radio station hack airs hours of vulgar “furry sex” ramblings

    Some Tuesday morning listeners of KIFT, a Top 40 radio station located in Breckenridge, Colorado, were treated to a radically different programming menu than they were used to. Instead of the normal fare from Taylor Swift, The Chainsmokers, or other pop stars, a hack by an unknown party caused one of the station's signals to broadcast a sexually explicit podcast related to the erotic attraction to furry characters. The unauthorized broadcast lasted for about 90 minutes.

    KIFT wasn't the only station to be hit by the hack. On the same day, Livingston, Texas-based country music station KXAX also broadcast raunchy furry-themed audio. And according to an article posted Wednesday by radio industry news site RadioInsight.com, the unauthorized broadcasts from a hobbyist group called FurCast were also forced on an unnamed station in Denver and an unidentified national syndicator.

  • Maryland hospital: Ransomware success wasn’t IT department’s fault

    MedStar refused to respond to Ars Technica's inquiries about the attack. In the statement released to media, MedStar's spokesperson said, "As we have said before, based on the advice of IT, cybersecurity and law enforcement experts, MedStar will not be elaborating further on additional aspects of this malware event. This is not only for the protection and security of MedStar Health, its patients and associates, but is also for the benefit of other healthcare organizations and companies." The spokesperson claimed the hospital had "no evidence of any compromise of patient or associate data… furthermore, we are pleased that we brought our systems back up in what can only be viewed as a very rapid recovery led by dedicated MedStar and external IT expert partners."

  • Its a good thing SELinux blocks access to the docker socket.

    I have seen lots of SELinux bugs being reported where users are running a container that volume mounts the docker.sock into a container. The container then uses a docker client to do something with docker. While I appreciate that a lot of these containers probbaly need this access, I am not sure people realize that this is equivalent to giving the container full root outside of the contaienr on the host system. I just execute the following command and I have full root access on the host.

  • Linux botnet attacks increase in scale

    Hackers are using malware which targets Linux to build botnets to launch distributed denial of service (DDoS attacks) security researchers have warned.

    The so-called BillGates Trojan botnet family of malware - apparently so named by the virus writers because it targets machines running Linux, not Windows - has been labelled with a "high" risk factor in a threat advisory issued by Akamai's Security Intelligence Research Team.

  • Ubuntu patches Linux kernel security bugs
  • Linux Kernel Security Bugs Patched

    Ubuntu users can install the update via the Unity Dash. To update, search the Unity Dash for the Software Updater utility and allow the program to reload the software repositories and search for new drivers. Once the Software Updater has found the updates, simply click on the "Install All" button to install them on your machine. Since this is a kernel update, you will need to reboot your device after the update. Canonical notes that the kernel updates have been given a new version number, which may require some users to recompile and reinstall all third party kernel modules.

Linux Practicality vs Activism

One of the greatest things about running Linux is the freedom it provides. Where the division among the Linux community appears is in how we value this freedom. For some, the freedom enjoyed by using Linux is the freedom from vendor lock-in or high software costs. Most would call this a practical consideration. Others users would tell you the freedom they enjoy is software freedom. This means embracing Linux distributions that support the Free Software Movement, avoiding proprietary software completely and all things related. In this article, I'll walk you through some of the differences between these two freedoms and how they affect Linux usage. Read more
