CVE-2008-5236
HighSummary
W xine-lib w wersji 1.1.12 oraz wcześniejszych (do 1.1.15) występują wielokrotne przepełnienia bufora w stercie, które mogą pozwolić zdalnym atakującym na wykonanie dowolnego kodu. Problemy te są związane z przetwarzaniem określonych elementów EBML oraz kombinacji wartości w funkcjach demuxujących.
Risk Assessment
Atakujący może wykorzystać te podatności do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów korzystających z podatnej wersji xine-lib.
Recommendation
Zaleca się aktualizację xine-lib do najnowszej wersji, aby usunąć te podatności oraz zastosowanie dodatkowych środków zabezpieczających w celu ochrony przed potencjalnymi atakami.

Original NVD description (English source)
Multiple heap-based buffer overflows in xine-lib 1.1.12, and other 1.1.15 and earlier versions, allow remote attackers to execute arbitrary code via vectors related to (1) a crafted EBML element length processed by the parse_block_group function in demux_matroska.c; (2) a certain combination of sps, w, and h values processed by the real_parse_audio_specific_data and demux_real_send_chunk functions in demux_real.c; and (3) an unspecified combination of three values processed by the open_ra_file function in demux_realaudio.c. NOTE: vector 2 reportedly exists because of an incomplete fix in 1.1.15.
