FFmpeg before 2.8.12, 3.0.x and 3.1.x before 3.1.9, 3.2.x before 3.2.6, and 3.3.x before 3.3.2 does not properly restrict HTTP Live Streaming filename extensions and demuxer names, which allows attackers to read arbitrary files via crafted playlist data.
libavcodec/webp.c in FFmpeg before 2.8.12, 3.0.x before 3.0.8, 3.1.x before 3.1.8, 3.2.x before 3.2.5, and 3.3.x before 3.3.1 does not ensure that pix_fmt is set, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to the vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions.
FFmpeg before 2017-03-05 has an out-of-bounds write caused by a heap-based buffer overflow related to the ff_h264_slice_context_init function in libavcodec/h264dec.c.
FFmpeg before 2017-02-07 has an out-of-bounds write caused by a heap-based buffer overflow related to the decode_frame function in libavcodec/pictordec.c.
FFmpeg before 2017-02-04 has an out-of-bounds write caused by a heap-based buffer overflow related to the decode_frame_common function in libavcodec/pngdec.c.
FFmpeg before 2017-01-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the ipvideo_decode_block_opcode_0xA function in libavcodec/interplayvideo.c and the avcodec_align_dimensions2 function in libavcodec/utils.c.
FFmpeg before 2017-01-23 has an out-of-bounds write caused by a stack-based buffer overflow related to the decode_zbuf function in libavcodec/pngdec.c.
Heap-based buffer overflow in libavformat/http.c in FFmpeg before 2.8.10, 3.0.x before 3.0.5, 3.1.x before 3.1.6, and 3.2.x before 3.2.2 allows remote web servers to execute arbitrary code via a negative chunk size in an HTTP response.
Heap-based buffer overflow in libavformat/rtmppkt.c in FFmpeg before 2.8.10, 3.0.x before 3.0.5, 3.1.x before 3.1.6, and 3.2.x before 3.2.2 allows remote attackers to execute arbitrary code by leveraging failure to check for RTMP packet size mismatches.
Heap-based buffer overflow in ffserver.c in FFmpeg before 2.8.10, 3.0.x before 3.0.5, 3.1.x before 3.1.6, and 3.2.x before 3.2.2 allows remote attackers to execute arbitrary code by leveraging failure to check chunk size.
