The _TIFFmalloc function in tif_unix.c in LibTIFF 4.0.3 does not reject a zero size, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image that is mishandled by the TIFFWriteScanline function in tif_write.c, as demonstrated by tiffdither.

Buffer overflow in the PixarLogDecode function in tif_pixarlog.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted TIFF image, as demonstrated by overwriting the vgetparent function pointer with rgb2ycbcr.

LibTIFF 4.0.7 allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted TIFF image, related to "WRITE of size 2048" and libtiff/tif_next.c:64:9.

tools/tiffcrop.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (heap-based buffer over-read and buffer overflow) or possibly have unspecified other impact via a crafted TIFF image, related to "READ of size 1" and libtiff/tif_fax3.c:413:13.

LibTIFF 4.0.7 allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted TIFF image, related to "READ of size 8" and libtiff/tif_read.c:523:22.

LibTIFF 4.0.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image, related to libtiff/tif_read.c:351:22.

LibTIFF 4.0.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image, related to libtiff/tif_ojpeg.c:816:8.

tools/tiffcp.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (integer underflow and heap-based buffer under-read) or possibly have unspecified other impact via a crafted TIFF image, related to "READ of size 78490" and libtiff/tif_unix.c:115:23.

Off-by-one error in the t2p_readwrite_pdf_image_tile function in tools/tiff2pdf.c in LibTIFF 4.0.7 allows remote attackers to have unspecified impact via a crafted image.

Integer overflow in tools/tiffcp.c in LibTIFF 4.0.7, 3.9.3, 3.9.4, 3.9.5, 3.9.6, 3.9.7, 4.0.0alpha4, 4.0.0alpha5, 4.0.0alpha6, 4.0.0beta7, 4.0.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.4beta, 4.0.5 and 4.0.6 allows remote attackers to have unspecified impact via a crafted image, which triggers a heap-based buffer overflow.

Heap-based buffer overflow in the readContigStripsIntoBuffer function in tif_unix.c in LibTIFF 4.0.7, 3.9.3, 3.9.4, 3.9.5, 3.9.6, 3.9.7, 4.0.0alpha4, 4.0.0alpha5, 4.0.0alpha6, 4.0.0beta7, 4.0.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.4beta, 4.0.5 and 4.0.6 allows remote attackers to have unspecified impact via a crafted image.

LibTIFF version 4.0.7 is vulnerable to a heap buffer overflow in the tools/tiffcp resulting in DoS or code execution via a crafted BitsPerSample value.

tools/tiffcp.c in libtiff 4.0.6 has an out-of-bounds write on tiled images with odd tile width versus image width. Reported as MSVR 35103, aka "cpStripToTile heap-buffer-overflow."

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."
