"NVD reports :

The decode_ihdr_chunk function in libavcodec/pngdec.c in FFmpeg before
2.7.2 does not enforce uniqueness of the IHDR (aka image header) chunk
in a PNG image, which allows remote attackers to cause a denial of
service (out-of-bounds array access) or possibly have unspecified
other impact via a crafted image with two or more of these chunks.

Multiple integer underflows in the ff_mjpeg_decode_frame function in
libavcodec/mjpegdec.c in FFmpeg before 2.7.2 allow remote attackers to
cause a denial of service (out-of-bounds array access) or possibly
have unspecified other impact via crafted MJPEG data.

The ff_sbr_apply function in libavcodec/aacsbr.c in FFmpeg before
2.7.2 does not check for a matching AAC frame syntax element before
proceeding with Spectral Band Replication calculations, which allows
remote attackers to cause a denial of service (out-of-bounds array
access) or possibly have unspecified other impact via crafted AAC
data.

The ff_mpv_common_init function in libavcodec/mpegvideo.c in FFmpeg
before 2.7.2 does not properly maintain the encoding context, which
allows remote attackers to cause a denial of service (invalid pointer
access) or possibly have unspecified other impact via crafted MPEG
data.

The destroy_buffers function in libavcodec/sanm.c in FFmpeg before
2.7.2 does not properly maintain height and width values in the video
context, which allows remote attackers to cause a denial of service
(segmentation violation and application crash) or possibly have
unspecified other impact via crafted LucasArts Smush video data.

The allocate_buffers function in libavcodec/alac.c in FFmpeg before
2.7.2 does not initialize certain context data, which allows remote
attackers to cause a denial of service (segmentation violation) or
possibly have unspecified other impact via crafted Apple Lossless
Audio Codec (ALAC) data.

The sws_init_context function in libswscale/utils.c in FFmpeg before
2.7.2 does not initialize certain pixbuf data structures, which allows
remote attackers to cause a denial of service (segmentation violation)
or possibly have unspecified other impact via crafted video data.

The ff_frame_thread_init function in libavcodec/pthread_frame.c in
FFmpeg before 2.7.2 mishandles certain memory-allocation failures,
which allows remote attackers to cause a denial of service (invalid
pointer access) or possibly have unspecified other impact via a
crafted file, as demonstrated by an AVI file.

The ff_rv34_decode_init_thread_copy function in libavcodec/rv34.c in
FFmpeg before 2.7.2 does not initialize certain structure members,
which allows remote attackers to cause a denial of service (invalid
pointer access) or possibly have unspecified other impact via crafted
(1) RV30 or (2) RV40 RealVideo data."
