Beskrivelse:
Der er rapporteret nogle sårbarheder i FFmpeg, som kan udnyttes af ondsindede personer til at udføre et DoS (Denial of Service) eller potentielt kompromittere et sårbart system.

Sårbarhederne skyldes diverse ikke-kontrollerede buffere i libavformat/rm.c, libavformat/sierravmd.c, libavformat/smacker.c, libavformat/tta.c, libavcodec/vorbis.c, libavcodec/dtsdec.c, libavcodec/4xm.c, libavcodec/alac.c, libavcodec/cook.c, libavcodec/shorten.c, libavcodec/snow.c, libavcodec/tta.c og libavcodec/smacker.c. Dette kan udnyttes til at forårsage buffer overflows, når en specielt udformet media-fil åbnes.

Succesfuld udnyttelse kan potentielt muliggøre eksekvering af vilkårlig kode.

Løsning:
Sårbarhederne er rettet i CVS-depotet.
