Produktbeschreibung

Das BIOS ist die Firmware bei IBM PC kompatiblen Computern.

Angriff

Ein lokaler Angreifer kann mehrere Schwachstellen in Dell BIOS ausnutzen, um beliebigen Code auszuführen, den Stapelspeicher zu manipulieren, Informationen aus dem SMRAM in den Kernelbereich zu lecken, eine Denial-of-Service-Situation zu schaffen oder seine Privilegien zu erhöhen und die Sicherheitsmechanismen des Betriebssystems zu umgehen.
