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

Sårbarheden skyldes en uspecificeret fejl i håndteringen af Excel filer og kan udnyttes via en specielt udformet Excel fil med specielt udformet header information.

Succesfuld udnyttelse kan føre til eksekvering af vilkårlig kode men kræver at brugeren lokkes til at åbne en ondsindet Excel fil.
