Vulnerabilidades

The TIFFFetchShortPair function in tif_dirread.c in libtiff 3.8.0 allows remote attackers to cause a denial of service (application crash) via a crafted TIFF image that triggers a NULL pointer dereference, possibly due to changes in type declarations and/or the TIFFVSetField function.

libtiff up to 3.7.0 allows remote attackers to cause a denial of service (application crash) via a TIFF image header with a zero "YCbCr subsampling" value, which causes a divide-by-zero error in (1) tif_strip.c and (2) tif_tile.c, a different vulnerability than CVE-2004-0804.

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.

Heap-based buffer overflow in the OJPEGVSetField function in tif_ojpeg.c for libtiff 3.6.1 and earlier, when compiled with the OJPEG_SUPPORT (old JPEG support) option, allows remote attackers to execute arbitrary code via a malformed TIFF image.

Multiple integer overflows in libtiff 3.6.1 and earlier allow remote attackers to cause a denial of service (crash or memory corruption) via TIFF images that lead to incorrect malloc calls.

Integer overflow in (1) tif_dirread.c and (2) tif_fax3.c for libtiff 3.5.7 and 3.7.0 allows remote attackers to execute arbitrary code via a TIFF file containing a TIFF_ASCII or TIFF_UNDEFINED directory entry with a -1 entry count, which leads to a heap-based buffer overflow.

Integer overflow in the tiffdump utility for libtiff 3.7.1 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted TIFF file.

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.

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.

Vulnerability in tif_dirread.c for libtiff allows remote attackers to cause a denial of service (application crash) via a TIFF image that causes a divide-by-zero error when the number of row bytes is zero, a different vulnerability than CVE-2005-2452.
