Is anything going on in the InfoSec arena this week? I couldn’t tell. If you have been under a rock this week I have some news for you. There are two vulnerabilities in CPU designs that essentially put everything we thought we knew about computer security on its head. Meltdown and Spectre are vulnerabilities affecting virtually all modern CPUs. I don’t think I could ever visualize a complete picture of all the vulnerable systems that are impacted. But, to put it in perspective, my first Windows PC was a used Dell something or other with a 486 DX2 66 MHz CPU I got back in 1995. If I still had it, I would not need to patch it. But, if you have a 120 MHz Intel Pentium CPU based system laying around, it’s impacted.

The blast radius of these vulnerabilities is massive. Considering that, I am making a new section of the newsletter this week dedicated to Meltdown and Spectre. The reason for this is twofold: 1) There’s so much information in this space it could be a newsletter edition all by itself. 2) You might have some fatigue from these vulnerabilities. I don’t want you to skip over other awesome things in the newsletter. Scroll down past Tools for the Meltdown and Spectre section. Stay vigilant, keep your eyes open for patches, and rest assured Linus is PISSED.

Two personal notes:

  1. I ran my first Kubernetes Community meeting this week (and it was awesome)! Kubernetes 1.10 is coming Wednesday, March 21st.
  2. I have some job news coming very soon so stay tuned to

Why Raspberry Pi isn’t vulnerable to Spectre or Meltdown: “Both vulnerabilities exploit performance features (caching and speculative execution) common to many modern processors to leak data via a so-called side-channel attack. Happily, the Raspberry Pi isn’t susceptible to these vulnerabilities, because of the particular ARM cores that we use.”
