CVE-2013-2495
HighSummary
Funkcja iff_read_header w pliku iff.c w libavformat w FFmpeg do wersji 1.1.3 nieprawidłowo obsługuje rozmiary danych dla formatu Interchange File Format (IFF) podczas operacji związanych z fragmentem CMAP lub kodekiem wideo. Może to prowadzić do odmowy usługi (przepełnienie całkowite, dostęp do tablicy poza zakresem i awaria aplikacji) lub innych nieokreślonych skutków za pomocą spreparowanego nagłówka.
Risk Assessment
Atakujący zdalnie mogą wykorzystać tę podatność do spowodowania awarii aplikacji, co może prowadzić do przerwy w dostępności usług. Istnieje również ryzyko nieokreślonych skutków ubocznych, które mogą wpłynąć na integralność systemu.
Recommendation
Zaleca się aktualizację FFmpeg do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów pod kątem nieautoryzowanych prób dostępu.

Original NVD description (English source)
The iff_read_header function in iff.c in libavformat in FFmpeg through 1.1.3 does not properly handle data sizes for Interchange File Format (IFF) data during operations involving a CMAP chunk or a video codec, which allows remote attackers to cause a denial of service (integer overflow, out-of-bounds array access, and application crash) or possibly have unspecified other impact via a crafted header.
