CVE-2008-5014
HighSummary
W jslock.cpp w Mozilla Firefox 3.x przed wersją 3.0.2, Firefox 2.x przed wersją 2.0.0.18, Thunderbird 2.x przed wersją 2.0.0.18 oraz SeaMonkey 1.x przed wersją 1.1.13, zdalni atakujący mogą spowodować awarię usługi (crash) oraz potencjalnie wykonać dowolny kod, modyfikując obiekt window.__proto__.__proto__. To prowadzi do zablokowania nie-natywnego obiektu, co wywołuje błąd asercji związany z funkcją OBJ_IS_NATIVE.
Risk Assessment
Podatność ta stwarza ryzyko awarii aplikacji oraz możliwość wykonania złośliwego kodu, co może prowadzić do utraty danych lub przejęcia kontroli nad systemem przez atakującego.
Recommendation
Zaleca się aktualizację przeglądarki Firefox, Thunderbirda i SeaMonkey do najnowszych wersji, aby usunąć tę podatność oraz zminimalizować ryzyko ataków.

Original NVD description (English source)
jslock.cpp in Mozilla Firefox 3.x before 3.0.2, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying the window.__proto__.__proto__ object in a way that causes a lock on a non-native object, which triggers an assertion failure related to the OBJ_IS_NATIVE function.
