Update NOW! CVE-2018-1002105, with root access. ​Kubernetes’ first major security hole discovered | ZDNet

Posted by jpluimers on 2018/12/04

From [WayBack] ​Kubernetes’ first major security hole discovered | ZDNet in reverse order:

Fortunately, there is a fix, but some of you aren’t going to like it. You must upgrade Kubernetes. Now. Specifically, there are patched version of Kubernetes [WayBack] v1.10.11,  [WayBack] v1.11.5, [WayBack] v1.12.3, and [WayBack] v1.13.0-rc.1.

…

[WayBack] Red Hat said, “The privilege escalation flaw makes it possible for any user to gain full administrator privileges on any compute node being run in a Kubernetes pod. [WayBack] This is a big deal. Not only can this actor steal sensitive data or inject malicious code, but they can also bring down production applications and services from within an organization’s firewall.”

…

And the bug, [WayBack] CVE-2018-1002105, aka the Kubernetes privilege escalation flaw, is a doozy. It’s a [WayBack] CVSS 9.8 critical security hole.

Scott Hanselman on Witter: “Why should I care about Kubernetes, Docker, and Container Orchestration?”

Posted by jpluimers on 2018/02/08

An important question for many people, so if you want to know more or get started: [WayBack] Scott Hanselman on Twitter: “Why should I care about Kubernetes, Docker, and Container Orchestration?” followed by:

Yes, AKS is Azure Container Services (go figure!).

Notes

  • For burning, Scott recommends [WayBack] Etcher: Burn images to SD cards & USB drives, safely and easily (which is now also available as experimental [WayBack] Etcher CLI), I tended to use a script like below since I’m a command-line person, but since Etcher does write and verify in one run, I’m considering switching:
    1. find where the SD card is mounted on your Mac: diskutil list
    2. sudo su -
    3. execute this from the directory where you downloaded filling in targetDevice with the value from diskutil list

    targetDevice="disk9"
    imageName="2017-11-29-raspbian-stretch-lite"
    unzip -o ${imageName}.zip
    diskutil umount "/dev/${targetDevice}s1"; \
    dd bs=1m of="/dev/r${targetDevice}" if=${imageName}; \
    sync; \
    diskutil list; \
    diskutil eject "/dev/${targetDevice}"

jessie frazelle on Twitter: “Hire the people who will automate themselves out of a job, then just keep giving them jobs.”

Posted by jpluimers on 2017/12/31

This is what DevOps is all about: [WayBack] jessie frazelle on Twitter: “Hire the people who will automate themselves out of a job, then just keep giving them jobs.”

I had seen the tweet before, but forgot to save it. Jonas Bandi reminded me of it at [WayBack] Weekend Reader: End of Year Edition – reality-loop.

Jessie is doing great work. For instance, she developed and published contained.af, and nobody captured the flag yet: [WayBack] jessie frazelle on Twitter: «A year ago I made contained.af and it’s launched over 128,000 containers & no one has retrieved the flag».

The game runs in a container, gives you console access and has a bunch of questions. Still need to dig deeper in it, as it is a fascinating set-up. If you like to try it:

Wishing you a year where nobody captures your flags (:

Must read: [WayBack] Some Thoughts on the Docker-Kubernetes Announcement – Scott’s Weblog – The weblog of an IT pro specializing in cloud computing, virtualization, and networking, all with an open source view
