Security: CPU Bugs, Western Digital Back Doors

tuxmachines.org - Sun, 01/07/2018 - 16:46
  • 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.

Newly Installed Linux Mint 18.3 Sylvia Cinnamon Edition Won't Boot

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 15:23
Hi all, first time poster here.

I just installed Linux on my laptop as a replacement to Windows 8.1, which was running slowly. The steps I used to install it were fully formatting and wiping my hard drive using Parted Magic and then installing Linux Mint 18.3 via a bootable USB. As far as I can tell, the install was successful, but when I try to boot from the hard drive I get a message "checking media presence, no media present."

I would really appreciate any help anyone could give me to get this working. I'm sure there's a lot more info I could provide that would be helpful, but I'm a true newbie, so could really use some guidance. Thanks in advance!

LXer: Pros and cons of Linux

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 15:00
Published at LXer:

Windows today beats almost all the markets thanks to its simplicity and large number of programs and games in a free access. We are used to Windows since there are no compatible systems like Windows. However, it is not true. Unfortunately, most people are creatures of habit that's why it will take years for the Linux to take its place among the users.


dont want to see volumes in file manager

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 14:52

do either of you know a way to hide the volumes in the file manager?
The Deepin file manager shows all the volumes I CAN connect to, I do this via fstab and don't need the view, and it's only confusing.
Nautilus File Manager also displays the folders in which I have included the partitions twice, i. e. normally in the overview at the top left and then again at the bottom, as mounted.
I mount like this..
: > //ip/share/documents /home/tom/documents cifs.....


hmm...cannot add pictures from pasteboard?

I am not finding anything useful or helpful anymore at Linux Questions. So I think I am done. I am signed up for too many different forums as it is. So I am out of here. Good luck all and remember to have fun.

LXer: The Best Linux Distributions for 2018

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 11:12
Published at LXer:

It’s a new year and the landscape of possibility is limitless for Linux. Whereas 2017 brought about some big changes to a number of Linux distributions, I believe 2018 will bring serious stability and market share growth—for both the server and the desktop.



LinuxQuestions.org latest posts - Sun, 01/07/2018 - 10:10
I've been sporadically participating in site discussions but realized I never introduced myself. I came across this forum last year and it has helped me get a better understanding of open source software and the linux kernel.
I'm not a developer but I do enjoy surfing the command line and I dabble in python.

I'm hoping to bring open source to the enterprise and it'd be great to have the help of a professional. I'm spending weeks on projects that should take minutes. If you're interested in helping please let me know. Otherwise I look forward to chatting with the community

Greg Kroah-Hartman on Meltdown, Spectre and the Linux kernel

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 08:56

As the admin of a small "fleet" of Slackware desktops and servers, I can honestly say that I'm not looking forward to this:

Quote: And then keep updating them over the next few weeks, we are still working out lots of corner case bugs given that the testing involved here is complex given the huge variety of systems and workloads this affects Yoinks!

I'm glad though that a lot of very clever people are hard at work resolving this whole mess. Also I'm happy that most of the boxes at my company are AMD. I think I'm down to a measly 9-10 Intel boxes, so that's a good thing at least.

But yea, interesting times ahead indeed.

What is your plan/experience with all this? I for one intend to just apply whatever patches Pat + crew put out.

sort v8.25 coreutils incantation wanted, or did i find a bug?

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 08:42
edit: never mind, as usual i wasnt telling the full story, i was also using --key=4
and it turns out sometimes the first 2 fields did not have a space separated when
field 2 got too big for its britches. but still, how does one google about numbers with commas without getting comma separated fields? lol....
my google-fu is failing me tonight.

i want a linux sort incantation for a list of numbers with comas
Code: 1,233
3,500 but i keep getting google results for 'comma separated lists' :(

the '--human-numeric-sort' option mostly does it but it glitches at odd points, some numbers (no commas or perhaps fewer commas than the previous number?) show up out of place, then the sort continues ascending after that.

i'll take other pipeable commands or bash incantations.

[SOLVED] Command to Change Taskbar Settings?

thank you.
