Beskrivelse:
Der er rapporteret to sårbarheder i Microsoft DirectX, som kan udnyttes af ondsindede personer til at kompromittere en brugers system.

1) En fejl i DirectShow (quartz.dll) under fortolkningen af SAMI-filer (Synchronized Accessible Media Interchange) kan udnyttes til at forårsage et stack-baseret buffer overflow via en specielt udformet fil.

Succesfuld udnyttelse muliggør eksekvering af vilkårlig kode.

Sårbarheden er rapporteret i DirectX 7.0 og 8.1. Nyere versioner er ikke berørte.

2) En fejl i DirectShow under fortolkningen af AVI- og WAV-filer kan udnyttes til at eksekvere vilkårlig kode, når en bruger f.eks. besøger et ondsindet website.

Sårbarheden er rapporteret i DirectX 7.0 til og med 10.0.
