Ranije ovog mjeseca saznalo se za otkrivenu novu kriti\u010dnu ranjivost u Intel procesorima, nazvanu \u201eSpoiler\u201c. Stru\u010dnjaci koji su otkrili problem obavijestili su da procesori AMD i ARM nisu podlo\u017eni tome. Sada je kompanija AMD potvrdila da zbog arhitektonskih karakteristika Spoiler ne predstavlja prijetnju za njezine procesore.<\/p>\n

\"AMD<\/p>\n

Poput ranjivosti Spectre i Meltdown, novi problem le\u017ei u implementaciji mehanizama spekulativnog izvr\u0161enja naredbi u Intel procesorima. U AMD \u010dipovima ovaj mehanizam je druga\u010dije implementiran, a koristi se druga\u010diji pristup upravljanju operacijama u radnoj memoriji i ke\u0161u. Preciznije, Spoiler mo\u017ee pristupiti parcijalnim informacijama o adresi (iznad 11 bita adrese) tijekom u\u010ditavanja. Procesori AMD ne koriste parcijalne podudarnosti adresa iznad 11 bita adrese prilikom rje\u0161avanja sukoba u\u010ditavanja.<\/p>\n

\"AMD<\/p>\n

Va\u017eno je napomenuti da, iako se Spoiler, kao i Spectre, oslanja na mehanizam spekulativnog izvr\u0161enja naredbi, zatvaranje nove ranjivosti postoje\u0107im \u201ezakrpama\u201c protiv prethodnih eksploita ne\u0107e biti mogu\u0107e. To zna\u010di da su aktuelni Intel procesori potrebni novi zakrpe koje bi ponovno mogle utjecati na performanse \u010dipova. A u daljnjem razvoju, od Intela \u0107e se, naravno, zahtijevati ispravke na razini arhitekture. Kompanija AMD ne\u0107e morati poduzimati sli\u010dne korake.<\/p>\n

\"AMD<\/p>\n

Na kraju \u0107emo napomenuti da Spoiler utje\u010de na sve Intel procesore, po\u010dev\u0161i od Core \u010dipova prve generacije pa do aktuelnih Coffee Lake Refresh, kao i onih koje tek o\u010dekujemo, Cascade Lake i Ice Lake. Iako je Intel o problemu obavije\u0161ten jo\u0161 po\u010detkom prosinca pro\u0161le godine, a od trenutka javnog otkrivanja Spoilera pro\u0161lo je ve\u0107 vi\u0161e od deset dana, kompanija Intel jo\u0161 uvijek nije predstavila mogu\u0107e na\u010dine rje\u0161avanja problema niti je izjavila ne\u0161to slu\u017ebeno o tome.<\/p>\n
