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.

Multiple integer overflows in the (1) cvt_by_strip and (2) cvt_by_tile 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.

The _TIFFVGetField function in tif_dirinfo.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.

The NeXTDecode function in tif_next.c in LibTIFF allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted TIFF image, as demonstrated by libtiff5.tif.

The NeXTDecode function in tif_next.c in LibTIFF allows remote attackers to cause a denial of service (uninitialized memory access) via a crafted TIFF image, as demonstrated by libtiff5.tif.

tif_luv.c in libtiff allows attackers to cause a denial of service (out-of-bounds reads) via a crafted TIFF image.

tif_luv.c in libtiff allows attackers to cause a denial of service (out-of-bounds writes) via a crafted TIFF image, a different vulnerability than CVE-2015-8781.

tif_luv.c in libtiff allows attackers to cause a denial of service (out-of-bounds write) via an invalid number of samples per pixel in a LogL compressed TIFF image, a different vulnerability than CVE-2015-8782.

Multiple buffer overflows in libtiff before 4.0.3 allow remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) extension block in a GIF image or (2) GIF raster image to tools/gif2tiff.c or (3) a long filename for a TIFF image to tools/rgb2ycbcr.c. NOTE: vectors 1 and 3 are disputed by Red Hat, which states that the input cannot exceed the allocated buffer size.

The LZW decompressor in the gif2tiff tool in libtiff 4.0.3 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted GIF image.

Heap-based buffer overflow in the readgifimage function in the gif2tiff tool in libtiff 4.0.3 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted height and width values in a GIF image.

Stack-based buffer overflow in tif_dir.c in LibTIFF before 4.0.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted DOTRANGE tag in a TIFF image.

ppm2tiff does not check the return value of the TIFFScanlineSize function, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PPM image that triggers an integer overflow, a zero-memory allocation, and a heap-based buffer overflow.

Heap-based buffer overflow in tif_pixarlog.c in LibTIFF before 4.0.3 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted TIFF image using the PixarLog Compression format.

The t2p_read_tiff_init function in tiff2pdf (tools/tiff2pdf.c) in LibTIFF 4.0.2 and earlier does not properly initialize the T2P context struct pointer in certain error conditions, which allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image that triggers a heap-based buffer overflow.

Multiple integer overflows in tiff2pdf in libtiff before 4.0.2 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted tiff image, which triggers a heap-based buffer overflow.

Integer signedness error in the TIFFReadDirectory function in tif_dirread.c in libtiff 3.9.4 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a negative tile depth in a tiff image, which triggers an improper conversion between signed and unsigned types, leading to a heap-based buffer overflow.

Integer overflow in the ReadDirectory function in tiffdump.c in tiffdump in LibTIFF before 3.9.5 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted TIFF file containing a directory data structure with many directory entries.

Heap-based buffer overflow in tif_ojpeg.c in the OJPEG decoder in LibTIFF before 3.9.5 allows remote attackers to execute arbitrary code via a crafted TIFF file.

Heap-based buffer overflow in the thunder (aka ThunderScan) decoder in tif_thunder.c in LibTIFF 3.9.4 and earlier allows remote attackers to execute arbitrary code via crafted THUNDER_2BITDELTAS data in a .tiff file that has an unexpected BitsPerSample value.
