I found this great article of Anton Gostev about Spectre and Meltdown, so I’m reposting it here :

By now, most of you have probably already heard of the biggest disaster in the history of IT – Meltdown and Spectre security vulnerabilities which affect all modern CPUs, from those in desktops and servers, to ones found in smartphones. Unfortunately, there’s much confusion about the level of threat we’re dealing with here, because some of the impacted vendors need reasons to explain the still-missing security patches. But even those who did release a patch, avoid mentioning that it only partially addresses the threat. And, there’s no good explanation of these vulnerabilities on the right level (not for developers), something that just about anyone working in IT could understand to make their own conclusion.

The most new and dangerous bug around it’s the one called “shellshock”, this is a security bug in the widely used Unix Bash shell which was disclosed on 24 September 2014. Many Internet daemons, such as web servers, use Bash to process certain commands, allowing an attacker to cause vulnerable versions of Bash to execute arbitrary commands. This can allow an attacker to gain unauthorized access to a computer system.

The bug causes Bash to unintentionally execute commands when they are stored in specially crafted environment variables. Within days, a series of further related vulnerabilities in Bash were found, leading to the need for further patches.

Let’s see how to check if your computer or server is vulnerable.
