This update for tiff fixes the following issues:

Security issues fixed:

• CVE-2016-5315: The setByteArray function in tif_dir.c allowed remote attackers to cause a denial of service (out-of-bounds read) via a crafted tiff image. (bsc#984809)
• CVE-2016-10267: LibTIFF allowed remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image, related to libtiff/tif_ojpeg.c:816:8. (bsc#1017694)
• CVE-2016-10269: LibTIFF allowed remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted TIFF image, related to 'READ of size 512' and libtiff/tif_unix.c:340:2. (bsc#1031254)
• CVE-2016-10270: LibTIFF allowed remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted TIFF image, related to 'READ of size 8' and libtiff/tif_read.c:523:22. (bsc#1031250)
• CVE-2017-18013: In LibTIFF, there was a Null-Pointer Dereference in the tif_print.c TIFFPrintDirectory function, as demonstrated by a tiffinfo crash. (bsc#1074317)
• CVE-2017-7593: tif_read.c did not ensure that tif_rawdata is properly initialized, which might have allowed remote attackers to obtain sensitive information from process memory via a crafted image. (bsc#1033129)
• CVE-2017-7595: The JPEGSetupEncode function in tiff_jpeg.c allowed remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted image. (bsc#1033127)
• CVE-2017-7596: LibTIFF had an 'outside the range of representable values of type float' undefined behavior issue, which might have allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image. (bsc#1033126)
• CVE-2017-7597: tif_dirread.c had an 'outside the range of representable values of type float' undefined behavior issue, which might have allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image. (bsc#1033120)
• CVE-2017-7599: LibTIFF had an 'outside the range of representable values of type short' undefined behavior issue, which might have allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image. (bsc#1033113)
• CVE-2017-7600: LibTIFF had an 'outside the range of representable values of type unsigned char' undefined behavior issue, which might have allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image. (bsc#1033112)
• CVE-2017-7601: LibTIFF had a 'shift exponent too large for 64-bit type long' undefined behavior issue, which might have allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image. (bsc#1033111)
• CVE-2017-7602: LibTIFF had a signed integer overflow, which might have allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image. (bsc#1033109)
• Multiple divide by zero issues
• CVE-2016-5314: Buffer overflow in the PixarLogDecode function in tif_pixarlog.c allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted TIFF image, as demonstrated by overwriting the vgetparent function pointer with rgb2ycbcr. (bsc#987351 bsc#984808 bsc#984831)

It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
