Beskrivelse:
Der er rapporteret en sårbarhed i Mozilla-produkter, som potentielt kan udnyttes af ondsindede personer til at kompromittere en brugers system.

Sårbarheden skyldes en fejl under håndteringen af "about:blank" sider loadet af chrome i et addon. Dette kan udnyttes til at eksekvere vilkårlig scriptkode med chrome-rettigheder ved f.eks. at klikke et link åbnet i et "about:blank" vindue oprettet og populeret på bestemt måde af et addon.

Succesfuld udnyttelse forudsætter, at bestemte addons er installeret.

Sårbarheden er rapporteret i følgende produkter og versioner:
* Firefox 2.0.0.5
* Thunderbird 2.0.0.5
* SeaMonkey 1.1.3

NOTE: Version 2.0.0.6 forhindrer også udnyttelse af Firefox og Thunderbird som vektorer af en URI-håndteringssårbarhed i Microsoft Windows.
