SUSE-SU-2018:1835-1

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, tdimagelength is not checked. The value of tdimagelength can be directly controlled by an input file. In the ChopUpSingleUncompressedStrip function, the TIFFCheckMalloc function is called based on tdimagelength. 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: tifpredict.h and tifpredict.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: tifpredict.h and tifpredict.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).
