Kwetsbaarheden verholpen in Adobe Illustrator

Feiten: Adobe heeft meerdere kwetsbaarheden verholpen in Adobe Illustrator (versies 29.8.6, 30.3 en eerder).
Interpretaties: De kwetsbaarheden bevinden zich in de wijze waarop Adobe Illustrator speciaal vervaardigde bestanden verwerkt. Er is sprake van een out-of-bounds write, een NULL pointer dereference, een out-of-bounds read en een heap-based buffer overflow. Door deze fouten in de bounds checking tijdens het parsen van bestanden kan een aanvaller het programma laten crashen (denial-of-service), gevoelige geheugeninhoud uitlezen, of code uitvoeren binnen de context van de applicatie. De kwetsbaarheden zijn aanwezig in meerdere versies van Adobe Illustrator en worden misbruikt door het openen van kwaadaardig opgemaakte bestanden.
Oplossingen: Adobe heeft updates uitgebracht om de kwetsbaarheden in Adobe Illustrator te verhelpen. Zie bijgevoegde referenties voor meer informatie.
