The TIFFVGetField function in tifdir.c in libtiff 4.0.6 allows attackers to cause a denial of service (invalid memory write and crash) or possibly have unspecified other impact via crafted field data in an extension tag in a TIFF image. (CVE-2015-7554)

Heap-based buffer overflow in the PackBitsPreEncode function in tif_packbits.c in bmp2tiff in libtiff 4.0.6 and earlier allows remote attackers to execute arbitrary code or cause a denial of service via a large width field in a BMP image. (CVE-2015-8668)

Buffer overflow in the readextension function in gif2tiff.c in LibTIFF 4.0.6 allows remote attackers to cause a denial of service (application crash) via a crafted GIF file. (CVE-2016-3186) (the program gif2tiff has been obsoleted)

The fpAcc function in tif_predict.c in the tiff2rgba tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (divide-by-zero error) via a crafted TIFF image. (CVE-2016-3622)

The rgb2ycbcr tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (divide-by-zero) by setting the (1) v or (2) h parameter to 0. (CVE-2016-3623)

The TIFFVGetField function in tifdirinfo.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted TIFF image. (CVE-2016-3632)

Multiple integer overflows in the (1) cvtbystrip and (2) cvtbytile functions in the tiff2rgba tool in LibTIFF 4.0.6 and earlier, when -b mode is enabled,allow remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image, which triggers an out-of-bounds write. (CVE-2016-3945)

Heap-based buffer overflow in the horizontalDifference8 function in tif_pixarlog.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image to tiffcp. (CVE-2016-3990)

Heap-based buffer overflow in the loadImage function in the tiffcrop tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted TIFF image with zero tiles. (CVE-2016-3991)

PixarLogDecode() out-of-bound writes (CVE-2016-5314)
