As most of you probably know, there was the spectre/meltdown vulnerabilities that were discovered to affect nearly all computers (almost all computer chips manufactured within the last 20 years) in late 2017 and early 2018. I haven’t really seen much news about it recently as it seems to have fallen off the radar for most people.
I had forgotten about it completely until I saw a section in the new vSphere module for Icinga2 (awesome by the way!) that mentioned the BIOS version on my hosts:
So does this mean that I shouldn’t upgrade the BIOS if Spectre/meltdown requires a 2.7.0 BIOS version?
Is there anything that you guys have done to protect your systems against these vulnerabilities? Did you forget about it as well?
