Summary
Na architekturze arm64, instrukcja WASM `br_table` z dużą liczbą wpisów może spowodować, że etykieta będzie zbyt daleko od instrukcji, co prowadzi do obcięcia i niepoprawnego obliczenia adresu skoku. Ta podatność została naprawiona w wersjach Firefox 141, Firefox ESR 115.26, Firefox ESR 128.13, Firefox ESR 140.1, Thunderbird 141, Thunderbird 128.13 oraz Thunderbird 140.1.
Risk Assessment
Organizacje korzystające z podatnych wersji przeglądarek mogą być narażone na błędne obliczenia adresów skoków, co może prowadzić do nieprzewidzianych zachowań aplikacji lub potencjalnych luk w zabezpieczeniach.
Recommendation
Zaleca się aktualizację do najnowszych wersji Firefox i Thunderbird, aby usunąć tę podatność i zminimalizować ryzyko związane z jej wykorzystaniem.
