Beskrivelse:
SEC Consult har rapporteret en sårbarhed i Microsoft Internet Explorer, som kan udnyttes af ondsindede personer til at kompromittere en brugers system.

Sårbarheden skyldes, at JView Profiler COM-objektet (javaprxy.dll) ikke initialiseres korrekt i Internet Explorer via object-tagget. Dette kan udnyttes via et ondsindet website til at korrumpere hukommelsen.

Succesfuld udnyttelse muliggør eksekvering af vilkårlig kode, men forudsætter, at "javaprxy.dll" findes på systemet.

NOTE: "javaprxy.dll" er inkluderet i Microsoft Java Virtual Machine. Exploit-kode er offentligt tilgængelig.

Sårbarheden er bekræftet på et fuldt opdateret system med Internet Explorer 6.0, Microsoft VM (virtual machine) build 3802 og Microsoft Windows XP SP 2. Det rapporteres, at Internet Explorer version 5.01 og 5.5 også er berørte.
