Omschrijving

Microsoft heeft kwetsbaarheden verholpen in Windows.

Een kwaadwillende kan de kwetsbaarheden mogelijk misbruiken om beveiligingsmaatregelen te omzeilen, privileges te verhogen, willekeurige code uit te voeren en/of toegang te verkrijgen tot gevoelige informatie.

De 13 ernstigste kwetsbaarheden bevinden zich in verschillende Windows-componenten en hebben een CVSS-score van 9,0 of hoger. Afhankelijk van de betreffende kwetsbaarheid kan misbruik leiden tot het uitvoeren van willekeurige code of het verkrijgen van verhoogde rechten.

De betreffende kwetsbaarheden zijn weergegeven in onderstaande tabel.

De overige kwetsbaarheden variëren in ernst van gemiddeld tot hoog. Het voert te ver om iedere kwetsbaarheid afzonderlijk in detail te behandelen in deze advisory. Raadpleeg het MSRC-portaal voor aanvullende informatie over de afzonderlijke kwetsbaarheden en de beschikbare beveiligingsupdates.
