Gestern berich\u00adte\u00adten wir \u00fcber eine Rei\u00adhe Patches, die die soge\u00adnann\u00adte Melt\u00addown-L\u00fccke auf AMD-Sys\u00adte\u00admen schlie\u00ad\u00dfen soll\u00adte.

Ent\u00adge\u00adgen der Stel\u00adlung\u00adnah\u00adme Micro\u00adsofts<\/a> zu den Start\u00adpro\u00adble\u00admen soll es sich laut AMD<\/span> nicht um einen Patch f\u00fcr Melt\u00addown und Spect\u00adre, son\u00addern nur um einen f\u00fcr Spect\u00adre bzw. Vari\u00adan\u00adte 1 in der Goog\u00adle Pro\u00adject Zero Nomen\u00adkla\u00adtur han\u00addeln. Dem\u00adnach ist der Arti\u00adkel Micro\u00adsofts so feh\u00adler\u00adhaft wie viel\u00adleicht manch eine Chip\u00adsatz\u00addo\u00adku. Den genau\u00aden Feh\u00adler, der zu dem Blue\u00adscreen f\u00fchrt, konn\u00adte man uns indes nicht mit\u00adtei\u00adlen, und so bleibt die\u00adser Punkt im Raum der Spekulation.<\/p>\n

Micro\u00adsoft has just con\u00adfirm\u00aded issues with a series of Melt\u00addown and Spect\u00adre<\/strong> secu\u00adri\u00adty updates for Win\u00addows devices run\u00adning on AMD<\/span> chip\u00adsets, and the com\u00adpa\u00adny tem\u00adpo\u00adr\u00ada\u00adri\u00adly pul\u00adled all the\u00adse patches to pre\u00advent fur\u00adther issues on the impac\u00adted computers.<\/p><\/blockquote>\n

Das passt dann auch wie\u00adder zu AMDs Stel\u00adlung\u00adnah\u00adme.<\/a> Die\u00adse ist bez\u00fcg\u00adlich der Vari\u00adan\u00adte 2 Branch Tar\u00adget Injec\u00adtion, wel\u00adche eben\u00adfalls zu Spect\u00adre z\u00e4hlt, noch sehr vage for\u00admu\u00adliert. So hei\u00dft es dort schlicht, dass die Angreif\u00adbar\u00adkeit von AMD-Hard\u00adware nahe\u00adzu null sei, es g\u00e4be ja auch noch kei\u00adne Demons\u00adtra\u00adti\u00adon des Sze\u00adna\u00adri\u00ados auf AMD-Hard\u00adware. Bei Vari\u00adan\u00adte 3, wel\u00adche als Melt\u00addown bekannt ist, spricht AMD<\/span> hin\u00adge\u00adgen kla\u00adre Wor\u00adte: Kei\u00adne Anf\u00e4l\u00adlig\u00adkeit wegen Architekturunterschieden.<\/p>\n\n\n\n\n\n\n\n

Auch bei der Vari\u00adan\u00adte 1, die von Micro\u00adsoft gepatched wer\u00adden soll, han\u00addelt es sich um eine L\u00fccke, die laut AMD<\/span> auf fast allen Sys\u00adte\u00admen durch die Vor\u00adein\u00adstel\u00adlung deak\u00adti\u00adviert ist.
