Buffer overflow in the readgifimage function in gif2tiff.c in the gif2tiff tool in LibTIFF 4.0.6 allows remote attackers to cause a denial of service (segmentation fault) via a crafted gif file.

The t2p_readwrite_pdf_image_tile function in LibTIFF allows remote attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a JPEG file with a TIFFTAG_JPEGTABLES of length one.

The TIFFFetchNormalTag function in LibTiff 4.0.6 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) by setting the tags TIFF_SETGET_C16ASCII or TIFF_SETGET_C32_ASCII to values that access 0-byte arrays. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9297.

The TIFFReadRawStrip1 and TIFFReadRawTile1 functions in tif_read.c in libtiff before 4.0.7 allows remote attackers to cause a denial of service (crash) or possibly obtain sensitive information via a negative index in a file-content buffer.

LibTIFF version 4.0.7 is vulnerable to a heap-based buffer over-read in tif_lzw.c resulting in DoS or code execution via a crafted bmp image to tools/bmp2tiff.

The DumpModeDecode function in libtiff 4.0.6 and earlier allows attackers to cause a denial of service (invalid read and crash) via a crafted tiff image.

The _TIFFFax3fillruns function in libtiff before 4.0.6 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted Tiff image.

Heap-based buffer overflow in tif_packbits.c in libtiff 4.0.6 and earlier allows remote attackers to crash the application via a crafted bmp file.

Out-of-bounds read in the PixarLogCleanup function in tif_pixarlog.c in libtiff 4.0.6 and earlier allows remote attackers to crash the application by sending a crafted TIFF image to the rgb2ycbcr tool.

Stack-based buffer overflow in the _TIFFVGetField function in libtiff 4.0.6 and earlier allows remote attackers to crash the application via a crafted tiff.
