Beskrivelse:
Der er rapporteret nogle sårbarheder i Mozilla Firefox, som kan udnyttes af ondsindede personer til at udføre cross-site scripting og spoofing-angreb og potentielt kompromittere en brugers system.

1) Diverse fejl i browser-enginen kan udnyttes til at korrumpere hukommelsen og potentielt eksekvere vilkårlig kode.

2) Diverse fejl i Javascript-enginen kan udnyttes til at korrumpere hukommelsen og potentielt eksekvere vilkårlig kode.

3) En fejl i "addEventListener" og "setTimeout" metoderne kan udnyttes til at indsætte script-kode i et andet sites kontekst og derved omgå "same-origin" politikken.

4) En fejl i cross-domain håndteringen kan udnyttes til at indsætte vilkårlig HTML og scriptkode i et andet websites sub-frame.

Dette er relateret til sårbarhed #5 i:
SA21906

5) En uspecificeret fejl under håndteringen af elementer udenfor dokumenter kan udnyttes til at kalde en event-handler og eksekvere vilkårlig kode med chrome-rettigheder.

6) En uspecificeret fejl under håndteringen af "XPCNativeWrapper" kan muliggøre eksekvering af vilkårlig kode.
