CVE-2016-2329 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-2329): libavcodec/tiff.c in FFmpeg before 2.8.6 does not properly validate RowsPerStrip values and YCbCr chrominance subsampling factors, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted TIFF file, related to the tiff_decode_tag and decode_frame functions. CVE-2016-2328 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-2328): libswscale/swscale_unscaled.c in FFmpeg before 2.8.6 does not validate certain height values, which allows remote attackers to cause a denial of service (out-of-bounds array read access) or possibly have unspecified other impact via a crafted .cine file, related to the bayer_to_rgb24_wrapper and bayer_to_yv12_wrapper functions. CVE-2016-2213 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-2213): The jpeg2000_decode_tile function in libavcodec/jpeg2000dec.c in FFmpeg before 2.8.6 allows remote attackers to cause a denial of service (out-of-bounds array read access) via crafted JPEG 2000 data.
