Podjetje Intel je objavilo informacije o novi vrsti ranljivosti v svojih procesorjih \u2014 MDS (Microarchitectural Data Sampling). Tako kot prej\u0161nji napadi v razredu Spectre, tudi novi problemi lahko privedejo do uhajanja zaupnih podatkov operacijskega sistema, virtualnih strojev in tujih procesov. Trdi se, da so problemi najprej odkrili zaposleni in partnerji podjetja Intel med notranjim revizorjem. Junija in avgusta 2018 so o te\u017eavah v podjetju Intel poro\u010dili tudi neodvisni raziskovalci, po \u010demer je skoraj eno leto potekalo skupno delo s proizvajalci in razvijalci operacijskih sistemov za dolo\u010ditev mo\u017enih vektorjev napadov in dostavo popravkov. Procesorji AMD in ARM niso dovzetni za to te\u017eavo.\n<\/p>\n

\nUgotovljene ranljivosti:<\/p>\n

CVE-2018-12126 — MSBDS (Microarchitectural Store Buffer Data Sampling), obnavljanje vsebine shranjevalnih vrstic. Uporablja se v napadu Fallout. Stopnja nevarnosti je ocenjena na 6.5 to\u010dk (CVSS);<\/p>\n

CVE-2018-12127 — MLPDS (Microarchitectural Load Port Data Sampling), obnavljanje vsebine vhodnih portov. Uporablja se v napadu RIDL. CVSS 6.5;<\/p>\n

CVE-2018-12130 — MFBDS (Microarchitectural Fill Buffer Data Sampling), obnavljanje vsebine polnilnih vrstic. Uporablja se v napadih ZombieLoad in RIDL. CVSS 6.5;<\/p>\n

CVE-2019-11091 — MDSUM (Microarchitectural Data Sampling Uncacheable Memory), obnavljanje vsebine pomnilnika, ki ni predpomnjen. Uporablja se v napadu RIDL. CVSS 3.8. <\/p>\n<\/blockquote>\n
