Intel shares fall as worries mount over chip flaw costs

Postado Janeiro 13, 2018

While in theory, it appears that the performance of PCs might take a hit, the impact for average computer users wouldn't be significant. They updated on steps they have taken after The Register publicly exposed the vulnerabilities in Intel Chips on Tuesday. "We are in the process of deploying mitigations to cloud services and have also released security updates to protect Windows customers against vulnerabilities affecting supported hardware chips from Intel, ARM, and AMD", it went on to say.

Security researchers had disclosed two security flaws exposing vulnerability of almost every modern computing device containing chips from Intel, Advanced Micro Devices and ARM Holdings.

Desktops, laptops, cloud servers, and smartphones are affected by one or both vulnerabilities, the researchers warn. Sony, the other major console manufacturer, whose Playstation also uses custom AMD processor, has not responded or confirmed about the effect of Meltdown on its game consoles.

The news prompted Intel's shares to slide more than 2 percent during trading on Thursday. "These new exploits leverage data about the proper operation of processing techniques common to modern computing platforms, potentially compromising security even though a system is operating exactly as it is created to".

Microsoft and Google have said they expect few performance problems for most of their cloud computing customers. "Most of the software vendors welcome that interaction as long as you see this disclosure in private first, so you have a chance to fix the bugs".

"Businesses and consumers should update operating systems and apply patches as soon as they become available".

Intel said in a statement it has already issued updates "for the majority of processor products introduced within the past five years". If the processor can't enforce the privileges, this flaw will let other standard programs access the restricted locations such as natively coded programs and content on the web using JavaScript.

The chip design flaws, which affect everything from iOS and macOS to Linux and Windows, could lead to hackers extracting important protected information such as passwords and encryption keys from programmes and operating systems if exploited. "The good news is that Spectre is harder to exploit". The company in its presentation also says the exploits do not impact just "one architecture or processor implementation".

We've since learned that this "chipgate" is actually about two critical vulnerabilities in modern processors called Meltdown and Spectre. They are from Google's Project Zero, the University of Pennsylvania, Austria's Graz University of Technology, Australia's University of Adelaide and security firms Cyberus Technology, Rambus and Data61.
