CVE-2008-3910
HighSummary
dns2tcp w wersjach przed 0.4.1 nieprawidłowo obsługuje wartości ujemne w pewnym polu długości w argumencie wejściowym do funkcji (1) dns_simple_decode lub (2) dns_decode, co pozwala zdalnym atakującym na nadpisanie bufora oraz wywołanie nieokreślonych innych skutków.
Risk Assessment
Podatność ta może prowadzić do zdalnego wykonania kodu lub destabilizacji systemu, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację dns2tcp do wersji 0.4.1 lub nowszej, aby usunąć tę podatność oraz zminimalizować ryzyko ataków.
