Kernel 4.14.15 fixes 2 on 3 Variants of Specter & Meltdown

Kernel 4.14.15: Vulnerabilities Specter and Meltdown they also affect Linux systems. The development teams of the distributions are reportedly preparing updated kernels, and everyone should update the browser they are using.

Previously publication we mentioned for a script which can check if the Linux distribution you are using is vulnerable to vulnerabilities 1 and 2 or in Meltdown attacks.

The script checks each variant separately and displays the results. If it displays "STATUS: VULNERABLE" the system is vulnerable and needs immediate (and if available) Kernel upgrade.

As you can see in the above , με παλαιότερο kernel, ένα από τα συστήματα που χρησιμοποιώ παραμένει ευπαθές στα κενά ασφαλείας Specter και Meltdown, τουλάχιστον στα 2 από τα 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, a representative of Cyberus Technology and a member of one of the three independent teams that discovered and reported Meltdown. The expert said that achieving comprehensive protection against Specter is very simple and will likely involve an "ongoing process" of fixes to and hardware modifications.

"The [Specter] attack scenario is not so simple, as it is very likely that there will be cross- "without even the involvement of the OS," 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. "
