CVE-2012-1206
HighSummary
W Hancom Office 2010 SE 8.5.5 występuje wiele przepełnień całkowitych, które pozwalają zdalnym atakującym na wykonanie dowolnego kodu poprzez użycie dużych wartości wymiarów w obrazach JPG lub PNG. Problem ten występuje w modułach filtrów obrazów JPG i PNG, co prowadzi do przepełnienia bufora w pamięci heap.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów korzystających z tej wersji oprogramowania. Może to prowadzić do utraty danych lub przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację Hancom Office do najnowszej wersji, która zawiera poprawki bezpieczeństwa eliminujące tę podatność. Dodatkowo, należy ograniczyć możliwość otwierania nieznanych lub podejrzanych plików graficznych.

Original NVD description (English source)
Multiple integer overflows in Hancom Office 2010 SE 8.5.5 allow remote attackers to execute arbitrary code via large dimension values in a (1) JPG image to the ImportGR in the JPG image filter module (HncJpeg10.flt) or (2) PNG image to the PNG image filter module (HncPng10.flt), which triggers a heap-based buffer overflow.
