Summary: Security update for tiff

Details: This update for tiff fixes the following security issues: - CVE-2017-5225: Prevent heap buffer overflow in the tools/tiffcp that could have caused DoS or code execution via a crafted BitsPerSample value (bsc#1019611) - CVE-2018-7456: Prevent a NULL Pointer dereference in the function TIFFPrintDirectory when using the tiffinfo tool to print crafted TIFF information, a different vulnerability than CVE-2017-18013 (bsc#1082825) - CVE-2017-11613: Prevent denial of service in the TIFFOpen function. During the TIFFOpen process, td_imagelength is not checked. The value of td_imagelength can be directly controlled by an input file. In the ChopUpSingleUncompressedStrip function, the _TIFFCheckMalloc function is called based on td_imagelength. If the value of td_imagelength is set close to the amount of system memory, it will hang the system or trigger the OOM killer (bsc#1082332) - CVE-2016-10266: Prevent remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image, related to libtiff/tif_read.c:351:22 (bsc#1031263) - CVE-2018-8905: Prevent heap-based buffer overflow in the function LZWDecodeCompat via a crafted TIFF file (bsc#1086408) - CVE-2016-9540: Prevent out-of-bounds write on tiled images with odd tile width versus image width (bsc#1011839). - CVE-2016-9535: tif_predict.h and tif_predict.c had assertions that could have lead to assertion failures in debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with subsampling (bsc#1011846). - CVE-2016-9535: tif_predict.h and tif_predict.c had assertions that could have lead to assertion failures in debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with subsampling (bsc#1011846). - Removed assert in readSeparateTilesIntoBuffer() function (bsc#1017689). - CVE-2016-10095: Prevent stack-based buffer overflow in the _TIFFVGetField function that allowed remote attackers to cause a denial of service (crash) via a crafted TIFF file (bsc#1017690). - CVE-2016-8331: Prevent remote code execution because of incorrect handling of TIFF images. A crafted TIFF document could have lead to a type confusion vulnerability resulting in remote code execution. This vulnerability could have been be triggered via a TIFF file delivered to the application using LibTIFF's tag extension functionality (bsc#1007276). - CVE-2016-3632: The _TIFFVGetField function allowed remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted TIFF image (bsc#974621).
