CVE-2011-1276
HighSummary
Przepełnienie bufora w Microsoft Excel 2002 SP3, 2003 SP3 i 2007 SP2 oraz w wersjach Office 2004 i 2008 dla Mac, a także w Excel Viewer SP2 i Office Compatibility Pack dla formatów plików Word, Excel i PowerPoint 2007 SP2, umożliwia zdalnym atakującym wykonanie dowolnego kodu lub spowodowanie odmowy usługi (uszkodzenie pamięci) poprzez spreparowany arkusz kalkulacyjny Excel. Problem wynika z niewłaściwej walidacji informacji o rekordach.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, ponieważ umożliwia zdalne wykonanie kodu, co może prowadzić do przejęcia kontroli nad systemem lub utraty danych. Dodatkowo, może prowadzić do awarii usług związanych z aplikacjami biurowymi.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszych wersji, które zawierają poprawki bezpieczeństwa. Należy również ograniczyć otwieranie nieznanych lub podejrzanych plików Excel, aby zminimalizować ryzyko ataku.
