I run this kernel in Ubuntu 16,04 and it is mitigated against Meltdown with KPTI and mitigated against Spectre variant 1, and Firefox 58 is in the LTS version. You're good enough.

Do the new meltdown / spectre kernels update automatically or is this something I have to manually do using Synaptic Package Manager

For kernel updates follow this link and read through the thread.

Is the kernel posted above secure enough or is there a new more secure kernel which I should update to

run this command to find out

Code: [Select]
$ grep . /sys/devices/system/cpu/vulnerabilities/*

I used the script to check. Here is the report from your command:


Code: [Select]
/sys/devices/system/cpu/vulnerabilities/meltdown:Not affected
/sys/devices/system/cpu/vulnerabilities/spectre_v1:Mitigation: OSB (observable speculation barrier, Intel v6)
/sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation: Full AMD retpoline

It seems the new kernel 4.13.33 fixes the variant 2 version on an older amd at least.


I'm using latest kernel 4.15 on an AMD CPU too and I see this message on boot I can't just now remember. However, running
Code: [Select]
$ grep . /sys/devices/system/cpu/vulnerabilities/*
shows this:
Code: [Select]
/sys/devices/system/cpu/vulnerabilities/meltdown:Not affected
/sys/devices/system/cpu/vulnerabilities/spectre_v1:Vulnerable
/sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation: Full generic retpoline

I believe message on boot has something to do with last line of that output; full generic reptoline.

Hmmm... off to live in a cave in the middle of a forest (next to a river with plenty of fish)...  ;)

Will launch my secret nuclear weapons at Intel first...
Don't worry about artificial intelligence.  Worry about natural stupidity.  :)

Bad news is that now more than 200 different forms of malware have turned up in the "wild" modified to attempt to exploit the Spectre vulnerability, which indicates the probability that some sophisticated sleeper applications may evolve to pose a huge threat to Microsoft Windows.

Good news is that this week I will be posting several different alternative ways to monitor for the vulnerabilities besides the already available spectre-meltdown-checker. Debian has now backported the spectre-meltdown-checker for stretch.

Here's another nice article I just found on the web, it describes another way to check on meltdown-spectre http://kroah.com/log/blog/2018/01/19/meltdown-status-2/

Here's a nice article I just found while surfing the web https://insights.ubuntu.com/2018/01/17/spectre-mitigation-updates-available-for-testing-in-ubuntu-proposed

It says:
Quote
You are invited to test and provide feedback for the following updated Linux kernels.  We have also rebased all derivative kernels such as the public cloud kernels (Amazon, Google, Microsoft, etc) and the Hardware Enablement (HWE) kernels.

It provides links for the proposed kernels for Ubuntu 14.04, 16.04, 17.04, 17.10.
