CVE-2008-4024
HighSummary
Microsoft Office Word 2000 SP3, 2002 SP3 oraz Office 2004 dla Mac umożliwiają zdalnym atakującym wykonanie dowolnego kodu poprzez dokument Word zawierający spreparowane pole lcbPlcfBkfSdt w bloku informacji o pliku (FIB), co omija krok inicjalizacji i wywołuje 'dowolne zwolnienie pamięci', znane jako 'podatność na uszkodzenie pamięci w Wordzie'.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów korzystających z tych wersji Microsoft Office. Może to prowadzić do utraty danych lub przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację do najnowszych wersji Microsoft Office, które zawierają poprawki zabezpieczeń eliminujące tę podatność. Dodatkowo, należy ograniczyć otwieranie dokumentów z nieznanych źródeł.

Original NVD description (English source)
Microsoft Office Word 2000 SP3 and 2002 SP3 and Office 2004 for Mac allow remote attackers to execute arbitrary code via a Word document with a crafted lcbPlcfBkfSdt field in the File Information Block (FIB), which bypasses an initialization step and triggers an "arbitrary free," aka "Word Memory Corruption Vulnerability."
