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 tdnstrips value, which triggers an infinite loop.
Buffer overflow in the t2pwritepdfstring 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.
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.
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 NeXT RLE decoder in the TIFF library (libtiff) before 3.8.2 might allow context-dependent attackers to execute arbitrary code via unknown vectors involving decoding large RLE images.
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 PixarLog decoder in the TIFF library (libtiff) before 3.8.2 might allow context-dependent attackers to execute arbitrary code via unknown vectors.
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).
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 tdircount value in the TIFFFetchShortPair function in tifdirread.c.
A heap-based buffer overflow flaw was found in the way tiff2pdf, a TIFF image to a PDF document conversion tool, of libtiff, a library of functions for manipulating TIFF (Tagged Image File Format) image format files, performed write of TIFF image content into particular PDF document file, when not properly initialized T2P context struct pointer has been provided by tiff2pdf (application requesting the conversion) as one of parameters for the routine performing the write. A remote attacker could provide a specially-crafted TIFF image format file, that when processed by tiff2pdf would lead to tiff2pdf executable crash or, potentially, arbitrary code execution with the privileges of the user running the tiff2pdf binary.

A heap-based buffer overflow was found in the way libtiff, library for manipulating TIFF (Tagged Image File Format) image format files, processed certain TIFF images using PixarLog Compression format. An attacker could create a specially-crafted TIFF image that, when opened, could cause an application using libtiff to crash or, possibly, execute arbitrary code with the privileges of the user running the application.
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.
The TIFFToRGB function in libtiff before 3.8.1 allows remote attackers to cause a denial of service (crash) via a crafted TIFF image with Yr/Yg/Yb values that exceed the YCR/YCG/YCB values, which triggers an out-of-bounds read.
