The ffmpeg lavf demuxer allows user-assisted attackers to cause a denial of service (application crash) via a crafted GIF file, possibly related to gstreamer, as demonstrated by lol-giftopnm.gif.
Stack-based buffer overflow in the str_read_packet function in libavformat/psxstr.c in FFmpeg before r13993 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a crafted STR file that interleaves audio and video sectors.
Multiple buffer overflows in libavcodec in ffmpeg before 0.4.9_p20060530 allow remote attackers to cause a denial of service or possibly execute arbitrary code via multiple unspecified vectors in (1) dtsdec.c, (2) vorbis.c, (3) rm.c, (4) sierravmd.c, (5) smacker.c, (6) tta.c, (7) 4xm.c, (8) alac.c, (9) cook.c, (10) shorten.c, (11) smacker.c, (12) snow.c, and (13) tta.c. NOTE: it is likely that this is a different vulnerability than CVE-2005-4048 and CVE-2006-2802.
Heap-based buffer overflow in the avcodec_default_get_buffer function (utils.c) in FFmpeg libavcodec 0.4.9-pre1 and earlier, as used in products such as (1) mplayer, (2) xine-lib, (3) Xmovie, and (4) GStreamer, allows remote attackers to execute arbitrary commands via small PNG images with palettes.
