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.Show less

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.Show less

LibTIFF 3.9.0 ignores tags in certain situations during the first stage of TIFF file processing and does not properly handle this during the second stage, which allows remote attackers to cause a denial of service (application crash) via a crafted file, a different vulnerability than CVE-2010-2481.Show less

The TIFFReadDirectory function in LibTIFF 3.9.0 does not properly validate the data types of codec-specific tags that have an out-of-order position in a TIFF file, which allows remote attackers to cause a denial of service (application crash) via a crafted file, a different vulnerability than CVE-2010-2481.Show less

The TIFFRGBAImageGet function in LibTIFF 3.9.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a TIFF file with an invalid combination of SamplesPerPixel and Photometric values.Show less

LibTIFF 3.9.4 and earlier does not properly handle an invalid td_stripbytecount field, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted TIFF file, a different vulnerability than CVE-2010-2443.Show less

The TIFFExtractData macro in LibTIFF before 3.9.4 does not properly handle unknown tag types in TIFF directory entries, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted TIFF file.Show less

The TIFFVStripSize function in tif_strip.c in LibTIFF 3.9.0 and 3.9.2 makes incorrect calls to the TIFFGetField function, which allows remote attackers to cause a denial of service (application crash) via a crafted TIFF image, related to "downsampled OJPEG input" and possibly related to a compiler optimization that triggers a divide-by-zero error.Show less

The OJPEGPostDecode function in tif_ojpeg.c in LibTIFF 3.9.0 and 3.9.2, as used in tiff2ps, allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted TIFF image, related to "downsampled OJPEG input."Show less

The TIFFYCbCrtoRGB function in LibTIFF 3.9.0 and 3.9.2, as used in ImageMagick, does not properly handle invalid ReferenceBlackWhite values, which allows remote attackers to cause a denial of service (application crash) via a crafted TIFF image that triggers an array index error, related to "downsampled OJPEG input."Show less

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."Show less

The OJPEGReadBufferFill function in tif_ojpeg.c in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an OJPEG image with undefined strip offsets, related to the TIFFVGetField function.Show less

Stack-based buffer overflow in the TIFFFetchSubjectDistance function in tif_dirread.c in LibTIFF before 3.9.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long EXIF SubjectDistance field in a TIFF file.Show less

Integer overflow in the TIFFroundup macro in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted TIFF file that triggers a buffer overflow.Show less

Multiple integer overflows in inter-color spaces conversion tools in libtiff 3.8 through 3.8.2, 3.9, and 4.0 allow context-dependent attackers to execute arbitrary code via a TIFF image with large (1) width and (2) height values, which triggers a heap-based buffer overflow in the (a) cvt_whole_image function in tiff2rgba and (b) tiffcvt function in rgb2ycbcr.Show less

Multiple buffer underflows in the (1) LZWDecode, (2) LZWDecodeCompat, and (3) LZWDecodeVector functions in tif_lzw.c in the LZW decoder in LibTIFF 3.8.2 and earlier allow context-dependent attackers to execute arbitrary code via a crafted TIFF file, related to improper handling of the CODE_CLEAR code.Show less
