CVE-2012-1149
HighSummary
Przepełnienie całkowitej liczby w module vclmi.dll w OpenOffice.org (OOo) 3.3, 3.4 Beta oraz prawdopodobnie wcześniejszych wersjach, a także w LibreOffice przed wersją 3.5.3, umożliwia zdalnym atakującym spowodowanie awarii aplikacji oraz potencjalne wykonanie dowolnego kodu poprzez spreparowany obiekt obrazu osadzonego, co zostało zademonstrowane przez obraz JPEG w pliku .DOC, który wywołuje przepełnienie bufora w stercie.
Risk Assessment
Podatność ta może prowadzić do awarii aplikacji, co wpływa na dostępność usług w organizacji. Dodatkowo, możliwość wykonania dowolnego kodu stwarza poważne zagrożenie dla bezpieczeństwa danych i systemów.
Recommendation
Zaleca się aktualizację OpenOffice.org i LibreOffice do najnowszych wersji, aby usunąć tę podatność. Należy również monitorować i ograniczać otwieranie plików z niezaufanych źródeł.

Original NVD description (English source)
Integer overflow in the vclmi.dll module in OpenOffice.org (OOo) 3.3, 3.4 Beta, and possibly earlier, and LibreOffice before 3.5.3, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted embedded image object, as demonstrated by a JPEG image in a .DOC file, which triggers a heap-based buffer overflow.
