Beskrivelse:
Der er identificeret en sårbarhed i Microsoft Visual Basic for Applications (VBA) der giver ondsindede Office og HTML dokumenter mulighed for at forårsage et buffer overflow.

Problemet er at VBA (VBE.DLL og VBE6.DLL) ikke kontrollerer bestemte parametre korrekt før et dokument behandles. Dette giver ondsindede personer mulighed for at kreere et dokument der kan forårsage et buffer overflow og muligvis føre til eksekvering af vilkårlig kode.

Dette berører alle programmer der benytter VBA til at behandle dokumenter. Dette inkluderer Internet Explorer såfremt Microsoft Office programmer er installeret fordi Office dokumenter automatisk åbnes med en hjælpe applikation.
