Security: CPU Bugs, Western Digital Back Doors

Filed under
Security
  • There will always be hardware bugs

    By now everyone has seen the latest exploit, meltdown and spectre, complete with logos and full academic paper. The gist of this is that side channel attacks on CPUs are now actually plausible instead of mostly theoretical. LWN (subscribe!) has a good collection of posts about actual technical details and mitigations. Because this involves hardware and not just software, fixes get more complicated.

  • What are Meltdown and Spectre? Here’s what you need to know.
  • Intel faces class action lawsuits regarding Meltdown and Spectre

    The three lawsuits—filed in California, Indiana, and Oregon (PDF)—cite not just the security vulnerabilities and their potential impact, but also Intel's response time to them. Researchers notified Intel about the flaws in June. Now, Intel faces a big headache. The vast majority of its CPUs in use today are impacted, and more class action complaints may be filed beyond these three.

  • Western Digital My Cloud drives have a built-in backdoor

    Western Digital's network attached storage solutions have a newfound vulnerability allowing for unrestricted root access.
    James Bercegay disclosed the vulnerability to Western Digital in mid-2017. After allowing six months to pass, the full details and proof-of-concept exploit have been published. No fix has been issued to date.
    More troubling is the existence of a hard coded backdoor with credentials that cannot be changed. Logging in to Western Digital My Cloud services can be done by anybody using "mydlinkBRionyg" as the administrator username and "abc12345cba" as the password. Once logged in, shell access is readily available followed with plenty of opportunity for injection of commands.

GPL Violations: Grsecurity Carries on Bullying Bruce Perens, Israel Complies with AGPL, Xiaomi Violates GPL

  • Linux's Grsecurity dev team takes blog 'libel' fight to higher court
    Open Source Security, Inc., the maker of the Grsecurity Linux kernel patches, suffered a setback last month when San Francisco magistrate judge Laurel Beeler granted a motion by defendant Bruce Perens to dismiss the company's defamation claim, with the proviso that the tossed legal challenge could be amended. The code biz and its president Brad Spengler sued Perens over a blog post in June in which Perens said that using the firm's Grsecurity software could expose customers to a contributory infringement claim under the terms of the Linux kernel's GPLv2 license. Open Source Security contends that statement has damaged its business.
  • Israel’s Information and Communications Technology Authority Bows to Pressure to Comply with Affero GPL
    Under pressure from open source advocates, the Israeli Information and Communications Technology (ICT) Authority recently shared its first open source software, extensions made by the ICT Authority to the CKAN data portal platform to help make the platform usable in Hebrew. The CKAN software is an open source data portal platform used since 2016 by the ICT Authority to make Israeli government data open and available on its government database website. The CKAN software is licensed under the GNU AGPL Version 3 license, an “ultra-strong” open source license that requires users of modified versions of CKAN software to offer its source code, even in the absence of distribution, to users interacting with software over the Internet.
  • Xiaomi Violating GPL 2.0 License With Mi A1 Kernel Sources
    Xiaomi is in violation of the GPL 2.0 license of the Linux Kernel project by still not releasing the kernel sources for the Mi A1 Android One and has been publicly criticized on the matter by established Android developer Francisco Franco earlier this week. While the smartphone was released in September and the Chinese consumer electronics manufacturer’s official policy is to publicize kernel sources for its devices within three months of their market launch, the Android One edition of the Mi A1 remains undetailed in this regard. Mr. Franco — best known for his work on the Franco Kernel, one of the most popular custom OS cores in the Android ecosystem — had some harsh words for the company on Twitter, calling its laidback approach to publicizing the kernel sources for the Mi A1 “an embarrassment” for the open source community and the type of software it allows it to create its commercial devices in the first place.

Introducing my new friend: a Slimbook

I have been following Slimbook for some time now. As you probably know, they ship a KDE laptop that is very cool, with KDE Neon pre-installed. They have attended to a couple of events I have attended to so I have been able to test their laptops, get feedback from buyers and ask them questions directly. The fact that they are a Spanish company was a beautiful surprise, We do not have that many hardware integrators and vendors in Spain. But what definitely caught my attention was the fact that they pay a lot of attention to the software. They ship the laptops with Linux pre-installed. Ok, that is not new any more. But they do pre-install several different distros. Now, that’s uncommon. But news do not stop there. Read more
