Fatter stadig ikke, at de ikke har fikset det? "'Leakage ... is visible in all Intel generations starting from first-gen Core CPUs" By Thomas Claburn in San Francisco 5 Mar 2019 at 06:34 https://www.theregister.co.uk[...]

"The issue is separate from the Spectre vulnerabilities, and is not addressed by existing mitigations. It can be exploited from user space without elevated privileges." "Intel is said to have been informed of the findings on December 1, 2018. The chip maker did not immediately respond to a request for comment. The paper's release comes after the 90 day grace period that's common in the security community for responsible disclosure.Moghimi doubts Intel has a viable response. "My personal opinion is that when it comes to the memory subsystem, it's very hard to make any changes and it's not something you can patch easily with a microcode without losing tremendous performance," he said."So I don't think we will see a patch for this type of attack in the next five years and that could be a reason why they haven't issued a CVE."

Igen ligesom spectre og meltdown er det ikke et problem for almideligt single bruger system i hjemmet Issuet ligger i multibruger og multioOSsystemmer aka server situationer Det eneste angrebsvinkel jeg kan see fra en "fremmed" er via java script. Men de fleste nyere browser har allerede random timer tics til at besvaergeligoere denne slags angreb

#2 Nu er det nok også de færreste hjemme brugere som går "nok" op i sikkerhed til at bekymre sig om dette. Tag derimod de store server farme, cloud setups etc som kører på Intel hardware, det er dem som bliver ramt og det er desværre også der (For intel) at pengene er.

#3: Arh. About two thirds of the revenue stems from the PC Client Group, which generated $9.2 billion over Q3 2014. The Data Center Group brought in $3.7 billion, while the Internet of Things group and the Software And Services groups each brought in about half a billion in revenues. 2/3 dele af deres indtægt er fra "PC" markedet, i 2014 tal.

#4 I 2014 ja.. Der er mangel på Intel chips lige pt da der er stor efterspørgsel efter mere udstyr til datacentre da væksten er eksploderet på den front. Der er en grund til at AMDs primære fokus med ZEN har været deres EPYC serie rettet imod server markedet.

Efter Forbes skrev om det svarede intel: UpdateAfter initial publication, an Intel spokesperson provided this statement: "Intel received notice of this research, and we expect that software can be protected against such issues by employing side channel safe software development practices. This includes avoiding control flows that are dependent on the data of interest. We likewise expect that DRAM modules mitigated against Rowhammer style attacks remain protected. Protecting our customers and their data continues to be a critical priority for us and we appreciate the efforts of the security community for their ongoing research." In plain English, I think Intel is laying the blame for Spoiler on software developers who don’t follow “side channel safe software development practices”, and manufacturers of memory modules that have not “mitigated” against this kind of attack. In my view, if Spoiler was entirely due to sub-par software and memory modules, it would affect AMD processors as well. Intel’s statement does not change my take on this news. https://www.forbes.com[...]
