Kernel 4.14.15 fixes 2 on 3 Variants of Specter & Meltdown

4.14.15: Vulnerabilities Specter and Meltdown also affect Linux systems. Distribution development teams are reportedly preparing up-to-date kernels, and everyone should update their browsers as well.

Previously publication we mentioned for a script which can test whether your Linux distribution is vulnerable to Specter 1 and 2 vulnerabilities or Meltdown attacks.

The script checks each par separately and displays the results. If it shows “STATUS: VULNERABLE” it it is vulnerable and needs an immediate (and if available) Kernel upgrade.

Kernel

As you can see in the above image, with an older kernel, one of the systems I use remains vulnerable to the Specter and Meltdown security holes, at least 2 from 3 Variants.

Let's see the same test in the kernel 4.14.15

The new kernel 4.14.15 fixes 2 of the 3 Variants of Specter and Meltdown vulnerabilities. For those of you who use Linux, look in your distribution updates for the most recent updated kernel, and upgrade immediately.

It remains to be seen when the Spectre Variant 1 will be closed, the only one left. But let's not forget her statement by Werner Haas, εκπροσώπου  της Cyberus και μέλος μιας από τις τρεις ανεξάρτητες ομάδες που ανακάλυψαν και ανέφεραν το Meltdown. Ο ειδικός ανέφερε ότι η επίτευξη μιας συνολικής s against Specter is very simple and probably implies with a “continued ” with corrections to the software and modifications to the .

“The [Spectre] attack scenario is not that simple, as it is very likely that there will be attacks -application χωρίς καν την συμμετοχή του ", Said Haas.

"Therefore, a general solution like Meltdown seems unlikely. Therefore, I expect combined repairs to hardware / software defects along with the warning that the fight against Spectre will be an ongoing process. "
