Das Unternehmen Intel hat Informationen \u00fcber eine neue Klasse von Sicherheitsanf\u00e4lligkeiten in seinen Prozessoren ver\u00f6ffentlicht \u2013 MDS (Microarchitectural Data Sampling). \u00c4hnlich wie bei den fr\u00fcheren Spectre-Angriffen k\u00f6nnen auch die neuen Probleme zu einer Offenlegung vertraulicher Daten des Betriebssystems, virtueller Maschinen und fremder Prozesse f\u00fchren. Es wird behauptet, dass die Probleme zun\u00e4chst von Intel-Mitarbeitern und Partnern w\u00e4hrend eines internen Audits identifiziert wurden. Im Juni und August 2018 \u00fcbermittelten auch unabh\u00e4ngige Forscher Informationen \u00fcber die Probleme an Intel, woraufhin fast ein Jahr lang eine gemeinsame Arbeit mit Herstellern und Entwicklern von Betriebssystemen zur Identifizierung m\u00f6glicher Angriffsvektoren und zur Bereitstellung von Patches stattfand. Prozessoren von AMD und ARM sind von diesem Problem nicht betroffen.\n<\/p>\n
