Omschrijving
Microsoft heeft kwetsbaarheden verholpen in diverse Office producten.
Een kwaadwillende kan de kwetsbaarheden misbruiken om een beveiligingsmaatregel te omzeilen, zich voor te doen als andere gebruiker, toegang te krijgen tot gevoelige gegevens of willekeurige code uit te voeren in de context van het slachtoffer.
Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide bestand te openen of link te volgen.
