Omschrijving
Microsoft heeft kwetsbaarheden verholpen in Microsoft Office (inclusief SharePoint, Visio, Word, Excel en PowerPoint).
De kwetsbaarheden in Microsoft Office omvatten verschillende 'use after free'-fouten, heap-gebaseerde bufferoverflows en andere kwetsbaarheden die ongeautoriseerde aanvallers in staat stellen om willekeurige code uit te voeren op lokale machines. Deze kwetsbaarheden kunnen worden geëxploiteerd via speciaal vervaardigde documenten of door misbruik van onbetrouwbare gegevens, wat kan leiden tot ongeautoriseerde toegang en controle over systemen.
