The TIFFYCbCrtoRGB function in LibTIFF 3.9.0 and 3.9.2, as used in ImageMagick, does not properly handle invalid ReferenceBlackWhite values, which allows remote attackers to cause a denial of service (application crash) via a crafted TIFF image that triggers an array index error, related to "downsampled OJPEG input."
