as used in Google Chrome before 46.0.2490.71 and other products, relies on a
coefficient-partition count during multi-threaded operation, which allows
remote attackers to cause a denial of service (race condition and memory
corruption) or possibly have unspecified other impact via a crafted WebM file
(CVE-2015-6761).
The decode_ihdr_chunk function in libavcodec/pngdec.c in FFmpeg before 2.4.11
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 (CVE-2015-6818).
The ff_sbr_apply function in libavcodec/aacsbr.c in FFmpeg before 2.4.11 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 (CVE-2015-6820).
The ff_mpv_common_init function in libavcodec/mpegvideo.c in FFmpeg before
2.4.11 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 (CVE-2015-6821).
The destroy_buffers function in libavcodec/sanm.c in FFmpeg before 2.4.11
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 (CVE-2015-6822).
The allocate_buffers function in libavcodec/alac.c in FFmpeg before 2.4.11
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
(CVE-2015-6823).
The sws_init_context function in libswscale/utils.c in FFmpeg before 2.4.11
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 (CVE-2015-6824).
The ff_frame_thread_init function in libavcodec/pthread_frame.c in FFmpeg
before 2.4.11 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 (CVE-2015-6825).
The ff_rv34_decode_init_thread_copy function in libavcodec/rv34.c in FFmpeg
before 2.4.11 does not initialize certain structure members, which allows
remote attackers to cause a denial of service (invalid pointer access) ... [Please see the references for more information on the vulnerabilities]");
