tools/tiffcrop.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in buffers. Reported as MSVR 35093, MSVR 35096, and MSVR 35097.

tools/tiffcrop.c in libtiff 4.0.6 has an out-of-bounds read in readContigTilesIntoBuffer(). Reported as MSVR 35092.

tif_predict.h and tif_predict.c in libtiff 4.0.6 have assertions that can lead to assertion failures in debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with subsampling. Reported as MSVR 35105, aka "Predictor heap-buffer-overflow."

tif_write.c in libtiff 4.0.6 has an issue in the error code path of TIFFFlushData1() that didn't reset the tif_rawcc and tif_rawcp members. Reported as MSVR 35095, aka "TIFFFlushData1 heap-buffer-overflow."

An exploitable remote code execution vulnerability exists in the handling of TIFF images in LibTIFF version 4.0.6. A crafted TIFF document can lead to a type confusion vulnerability resulting in remote code execution. This vulnerability can be triggered via a TIFF file delivered to the application using LibTIFF's tag extension functionality.

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.

The DumpModeEncode function in tif_dumpmode.c in the bmp2tiff tool in LibTIFF 4.0.6 and earlier, when the "-c none" option is used, allows remote attackers to cause a denial of service (buffer over-read) via a crafted BMP image.

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.

The putcontig8bitCIELab function in tif_getimage.c in LibTIFF 4.0.6 allows remote attackers to cause a denial of service (out-of-bounds read) via a packed TIFF image.

tif_getimage.c in LibTIFF 4.0.6 allows remote attackers to cause a denial of service (out-of-bounds read) via the SamplesPerPixel tag in a TIFF image.
