Security experts have already uncovered two critical safety deficiencies in modern processors that, as soon as the attackers develop appropriate methods, have led to a series of new security incidents. These are security risks, called Meltdown and Specter, that are present in almost all modern processors that have been developed over the past decade. Recently, security experts have revealed that processors have a business Intel another security vulnerabilitywho was mentioned PortSmash.
The vulnerability of PortSmash is that Intel processors are vulnerable to a so-called side-channel vulnerability and that the process gains access to data that must be protected. Unfortunately, this is not just a theoretical vulnerability, because security experts on the GitHub web portal have already published a code-based code that can be used to alienate the private OpenSSL key from the TLS server. The new vulnerabilities can only be avoided by excluding HyperThreading technology, which is not easy to implement in practice, as personal computers and servers greatly degrade performance.
Intel has not yet revealed how they will fix the new vulnerability in their processors. At a competing AMD company, however, they are still considering whether their processors can also be vulnerable to PortSmash vulnerabilities. The first results of the research must be known in the coming weeks.
