CVE-2016-3658

In LibTIFF version 4.0.8, there is a heap-based use-after-free vulnerability in the t2p_writeproc function in tiff2pdf.c.

In LibTIFF version 4.0.9, there is a heap-based buffer over-read in the function PackBitsEncode in tif_packbits.c.

The pal2rgb tool in LibTIFF 4.0.9 has a vulnerability that allows remote attackers to cause application crashes via a crafted TIFF file due to a heap-based buffer overflow.

The TIFFReadDirEntryArray function in LibTIFF 4.0.8 mishandles memory allocation for short files, potentially leading to application crashes during tiff2pdf invocation.

There is a heap based buffer overflow in LibTIFF 4.0.8 in tools/tiff2pdf.c triggered by a PlanarConfig=Contig image. This can lead to an out-of-bounds write and potentially to remote denial of service or arbitrary code execution attacks.

In LibTIFF version 4.0.8, there is an assertion abort in the TIFFWriteDirectoryTagCheckedLong8Array function in tif_dirwrite.c. Crafted input can lead to a remote denial of service attack.

In LibTIFF 4.0.8, there is a heap-based buffer overflow in the t2p_write_pdf function, which could lead to various damages. A crafted TIFF document can lead to out-of-bounds read, invalid free, or memory corruption, potentially allowing arbitrary code execution.

LibTIFF version 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.

LibTIFF version 4.0.7 has an undefined behavior issue related to 'shift exponent too large for 64-bit type long', which may lead to application crashes.

LibTIFF version 4.0.7 has an undefined behavior issue related to values outside the range of representable values of type unsigned char, which may allow remote attackers to cause application crashes or possibly have unspecified other impacts via a crafted image.
