CVE-2012-3993
HighSummary
Implementacja Chrome Object Wrapper (COW) w Mozilla Firefox przed wersją 16.0, Firefox ESR 10.x przed 10.0.8, Thunderbird przed 16.0, Thunderbird ESR 10.x przed 10.0.8 oraz SeaMonkey przed 2.13 nieprawidłowo reaguje na błędy metod InstallTrigger, co pozwala zdalnym atakującym na wykonanie dowolnego kodu JavaScript z uprawnieniami chrome poprzez spreparowaną stronę internetową, związane z problemem 'zanieczyszczenia XrayWrapper'.
Risk Assessment
Podatność ta może prowadzić do wykonania złośliwego kodu w kontekście przeglądarki, co stwarza poważne zagrożenie dla bezpieczeństwa danych użytkowników oraz integralności systemu.
Recommendation
Zaleca się aktualizację przeglądarki Firefox, Thunderbird oraz SeaMonkey do najnowszych wersji, aby usunąć tę podatność oraz zminimalizować ryzyko ataków.

Original NVD description (English source)
The Chrome Object Wrapper (COW) implementation in Mozilla Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x before 10.0.8, and SeaMonkey before 2.13 does not properly interact with failures of InstallTrigger methods, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges via a crafted web site, related to an "XrayWrapper pollution" issue.
