CVE-2013-0875
HighSummary
Funkcja ff_add_png_paeth_prediction w libavcodec/pngdec.c w FFmpeg przed wersją 1.1.3 umożliwia zdalnym atakującym wywołanie nieokreślonego wpływu poprzez spreparowany obraz PNG, związany z dostępem do tablicy poza jej granicami.
Risk Assessment
Podatność ta może prowadzić do nieprzewidzianych zachowań aplikacji, co stwarza ryzyko dla integralności i dostępności systemu. Atakujący mogą wykorzystać tę lukę do przeprowadzenia ataków zdalnych.
Recommendation
Zaleca się aktualizację FFmpeg do wersji 1.1.3 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto monitorować i weryfikować obrazy PNG przed ich przetwarzaniem.
