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.

tif_pixarlog.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in heap allocated buffers. Reported as MSVR 35094, aka "PixarLog horizontalDifference heap-buffer-overflow."

Multiple stack-based buffer overflows in the TIFF library (libtiff) before 3.8.2, as used in Adobe Reader 9.3.0 and other products, allow context-dependent attackers to execute arbitrary code or cause a denial of service via unspecified vectors, including a large tdir_count value in the TIFFFetchShortPair function in tif_dirread.c.

Heap-based buffer overflow in the JPEG decoder in the TIFF library (libtiff) before 3.8.2 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via an encoded JPEG stream that is longer than the scan line size (TiffScanLineSize).

Stack-based buffer overflow in the tiffsplit command in libtiff 3.8.2 and earlier might might allow attackers to execute arbitrary code via a long filename. NOTE: tiffsplit is not setuid. If there is not a common scenario under which tiffsplit is called with attacker-controlled command line arguments, then perhaps this issue should not be included in CVE.

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."

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/tiff2pdf.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in heap allocated buffers in t2p_process_jpeg_strip(). Reported as MSVR 35098, aka "t2p_process_jpeg_strip 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."

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.

TIFF library (libtiff) before 3.8.2 allows context-dependent attackers to pass numeric range checks and possibly execute code, and trigger assert errors, via large offset values in a TIFF directory that lead to an integer overflow and other unspecified vectors involving "unchecked arithmetic operations".

Heap-based buffer overflow in the PixarLog decoder in the TIFF library (libtiff) before 3.8.2 might allow context-dependent attackers to execute arbitrary code via unknown vectors.

Buffer overflow in the t2p_write_pdf_string function in tiff2pdf in libtiff 3.8.2 and earlier allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a TIFF file with a DocumentName tag that contains UTF-8 characters, which triggers the overflow when a character is sign extended to an integer that produces more digits than expected in an sprintf call.

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.

Stack-based buffer overflow in libTIFF before 3.7.2 allows remote attackers to execute arbitrary code via a TIFF file with a malformed BitsPerSample tag.

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow.

Multiple vulnerabilities in the RLE (run length encoding) decoders for libtiff 3.6.1 and earlier, related to buffer overflows and integer overflows, allow remote attackers to execute arbitrary code via TIFF files.

tif_getimage.c in LibTIFF 3.9.0 and 3.9.2 on 64-bit platforms, as used in ImageMagick, does not properly perform vertical flips, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted TIFF image, related to "downsampled OJPEG input."

Unspecified vulnerability in the custom tag support for the TIFF library (libtiff) before 3.8.2 allows remote attackers to cause a denial of service (instability or crash) and execute arbitrary code via unknown vectors.

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.

The _TIFFVGetField function in tif_dir.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.

In LibTIFF 4.0.6 and possibly other versions, the program processes BMP images without verifying that biWidth and biHeight in the bitmap-information header match the actual input, as demonstrated by a heap-based buffer over-read in bmp2tiff. NOTE: mentioning bmp2tiff does not imply that the activation point is in the bmp2tiff.c file (which was removed before the 4.0.7 release).

tools/tiffcrop.c in libtiff 4.0.6 reads an undefined buffer in readContigStripsIntoBuffer() because of a uint16 integer overflow. Reported as MSVR 35100.

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.

tools/pal2rgb.c in pal2rgb in LibTIFF 4.0.9 allows remote attackers to cause a denial of service (TIFFSetupStrips heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted TIFF file.

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.

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.

The EstimateStripByteCounts function in TIFF library (libtiff) before 3.8.2 uses a 16-bit unsigned short when iterating over an unsigned 32-bit value, which allows context-dependent attackers to cause a denial of service via a large td_nstrips value, which triggers an infinite loop.

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.

Double free vulnerability in tif_jpeg.c in libtiff before 3.8.1 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image that triggers errors related to "setfield/getfield methods in cleanup functions."
