Se kdo še spomne Spectre v zadnjem letu dni, ki je v bistvu "šopek" eksplojtov, ki napadajo moderne processorje? Well, zdajle so researcherji pokazali na novo obliko napada na špekulativno procesiranje, ki ga izvajajo Intel Core processorji, in sicer vključno od prve generacije, do današnjih. Baje bo tole nemogoče pofixat v softwareu, v performančnem smislu izjemno drago v mikrokodi, in torej ne bo druge, kot da se tega lotijo na nivoju redesigna samega processorja. Torej še 5 let ne bomo videli popravkov.


"The root cause for SPOILER is a weakness in the address speculation of Intel’s proprietary implementation of the memory subsystem which directly leaks timing behavior due to physical address conflicts," the paper explains.


Zanimivo je, da so pretestirali tudi AMD in ARM processorje, ki pa niso dovzetni za to obliko napada. Kar je v bistvu dobra novica, vsaj za delničarje v AMD in ARMH. Torej za vsakogar od nas! Ajetkotkoje!
