CVE-2008-3471
HighSummary
W Microsoft Excel (w wersjach 2000 SP3, 2002 SP3, 2003 SP2 i SP3 oraz 2007 Gold i SP1) oraz w Office Excel Viewer i Office Compatibility Pack występuje przepełnienie bufora na stosie. Atakujący zdalnie mogą wykonać dowolny kod poprzez złośliwy plik BIFF, który wywołuje błędne obliczenia rozmiaru.
Risk Assessment
Podatność ta może prowadzić do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów organizacji. Atakujący mogą uzyskać pełną kontrolę nad zainfekowanym systemem.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszych wersji, które eliminują tę podatność. Należy również ograniczyć otwieranie plików BIFF z nieznanych źródeł.
