Intel Issues Meltdown, Spectre Patches For Newer CPUs

13 Enero 2018

In the wake of Meltdown and Spectre security flaws, Intel is now facing at least three class action lawsuits.

The stock sale in late November occurred more than five months after Intel was alerted to flaws in its chips. If you haven't already, uou can get up to speed in our FAQ on the subject, which explains both exploits and who is most at risk. According to the latest reports, there are some exciting details regarding the weakness and what is actually broken. The second bug named Spectre meanwhile affects chips made by Intel, ARM and AMD and lets hackers to trick 'error-free applications' to shell out sensitive information.

Intel confirmed that the researchers first alerted Intel to the flaws in June. Later that day, the Computer Emergency Response Team Coordination Center (CERT/CC) issued a security update that said the only way to protect against Spectre in particular would be to replace affected processors.

Unfortunately, the Microsoft fix may result in some performance dips. Barclays has actually raised its target price for INTC, however, from $45.26 to $55 a share.

They also plan to design their future chip architecture to prevent the exploits.

In the case of some discrete workloads where the performance impact will initially be higher, Intel expects the impact to be reduced by additional post-deployment identification, testing and improvement of the software updates.

"Processors have long been sold based solely on performance considerations, not security", says Watson. This also works for AMD systems that have been patched, as they are being 'fixed' regardless of whether these processors actually require the security fix or not. The company downplayed these issues in a statement on Wednesday, but it wasn't enough to prevent to stock from shedding another 3.4% by 11:30 a.m. EST on Thursday. AMD's EPYC server chips are in the beginning stages of assaulting Intel's server chip monopoly, and a closing of the performance gap could do wonders for its market share.

Second, the patches required to kill the Meltdown exploit will reportedly cause Intel processors to take a performance hit. At the centre of all this is Intel as it produces processors for a majority of computing devices around the world.

Two separate security flaws were discovered by researchers and disclosed this week.

So far, it has not received any reports of attacks due to the two critical flaws, dubbed Meltdown and Spectre. Known to have existed on devices released since 1995, these Intel CPU bugs could allow an attacker to access restricted areas of the operating system's kernel memory. So that includes your passwords, login keys, or any files that happen to be cached when unauthorized access occurs.

However, later on Thursday afternoon, CERT/CC withdrew that recommendation, saying merely that anybody affected should install operating system updates as soon as possible.
