CVE-2008-4211
HighSummary
Błąd związany z podpisywaniem liczb całkowitych w QuickLook w systemie Apple Mac OS X 10.5.5 oraz w Office Viewer w systemie iPhone OS 1.0 do 2.1 umożliwia zdalnym atakującym spowodowanie awarii aplikacji oraz wykonanie dowolnego kodu poprzez spreparowany plik Microsoft Excel, co prowadzi do nieautoryzowanego dostępu do pamięci.
Risk Assessment
Podatność ta może prowadzić do przerwania działania aplikacji oraz umożliwić atakującym wykonanie złośliwego kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów i danych użytkowników.
Recommendation
Zaleca się aktualizację systemów do najnowszych wersji, które eliminują tę podatność oraz monitorowanie i ograniczenie otwierania plików Excel z nieznanych źródeł.
