CVE-2013-2277
HighSummary
Funkcja ff_h264_decode_seq_parameter_set w pliku h264_ps.c w libavcodec w FFmpeg przed wersją 1.1.3 nie weryfikuje relacji między głębokością luminancji a głębokością chrominancji. To może umożliwić zdalnym atakującym spowodowanie odmowy usługi (dostęp do tablicy poza zakresem i awaria aplikacji) lub potencjalnie inne nieokreślone skutki za pomocą spreparowanych danych H.264.
Risk Assessment
Podatność ta może prowadzić do awarii aplikacji, co może zakłócić działanie usług w organizacji. Istnieje również ryzyko wykorzystania tej luki do przeprowadzenia bardziej złożonych ataków.
Recommendation
Zaleca się aktualizację FFmpeg do wersji 1.1.3 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto monitorować i ograniczać dostęp do aplikacji przetwarzających dane H.264.

Original NVD description (English source)
The ff_h264_decode_seq_parameter_set function in h264_ps.c in libavcodec in FFmpeg before 1.1.3 does not validate the relationship between luma depth and chroma depth, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted H.264 data.
