An issue was discovered in LibTIFF 4.0.9. There is a int32 overflow in multiply_ms in tools/ppm2tiff.c, which can cause a denial of service (crash) or possibly have unspecified other impact via a crafted image file.
newoffsets handling in ChopUpSingleUncompressedStrip in tif_dirread.c in LibTIFF 4.0.9 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted TIFF file, as demonstrated by tiff2pdf. This is a different vulnerability than CVE-2018-15209.
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.
LibTIFF 4.0.7 has a signed integer overflow, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted 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.
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.
Multiple integer overflows in tiff_getimage.c in LibTIFF 3.9.4 allow remote attackers to execute arbitrary code via a crafted tile size in a TIFF file, which is not properly handled by the (1) gtTileSeparate or (2) gtStripSeparate function, leading to a heap-based buffer overflow.
In LibTIFF 4.0.9, there is a heap-based buffer over-read in the function PackBitsEncode in tif_packbits.c.
A heap-based buffer overflow flaw was found in libtiff in the handling of TIFF images in libtiff's TIFF2PDF tool. A specially crafted TIFF file can lead to arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
