Meltdown et Spectre, le feuilleton continue. Apr\u00e8s Intel c'est au tour d'AMD d'admettre que ses processeurs sont aussi touch\u00e9s par le probl\u00e8me apr\u00e8s avoir dans un premier temps d\u00e9clar\u00e9 que l'impact de la d\u00e9couverte de ces failles serait “quasi-nul” pour l'entreprise. Les dice AMD seraient touch\u00e9s par deux variantes de la faille Spectre, la plus difficile \u00e0 patcher, qui permet d'acc\u00e9der aux donn\u00e9es d'autres applications en cours d'ex\u00e9cution. Des patch et mises \u00e0 jour du microcode des processeurs sont en cours de pr\u00e9paration et de d\u00e9ploiement.<\/strong><\/p>\n

Finalement, AMD est aussi touch\u00e9<\/strong>. Apr\u00e8s avoir dans un premier temps ni\u00e9 \u00eatre concern\u00e9 par les failles de s\u00e9curit\u00e9 mat\u00e9rielles Meltdown et Spectre<\/a>, le fondeur vient revenir sur ses d\u00e9clarations dans un communiqu\u00e9 publi\u00e9 dans la soir\u00e9e du jeudi 11 janvier. On y apprend qu'en r\u00e9alit\u00e9 la faille de s\u00e9curit\u00e9 Spectre concerne aussi les processeurs AMD – ils restent n\u00e9anmoins \u00e9pargn\u00e9s par la faille Meltdown, qui donne acc\u00e8s \u00e0 \u00e0 peu pr\u00e8s tout ce qui transite par le processeur. Deux variantes de cette faille seraient concern\u00e9es. Pour rappel, Spectre permet \u00e0 une personne mal intentionn\u00e9e d'acc\u00e9der discr\u00e8tement aux donn\u00e9es des applications en cours d'ex\u00e9cution.<\/p>\n
