  These security issues were fixed:

  - CVE-2017-18013: There was a Null-Pointer Dereference in the tif_print.c
  TIFFPrintDirectory function, as demonstrated by a tiffinfo crash.
  (bsc#1074317)

  - CVE-2018-10963: The TIFFWriteDirectorySec() function in tif_dirwrite.c
  allowed remote attackers to cause a denial of service (assertion failure
  and application crash) via a crafted file, a different vulnerability
  than CVE-2017-13726.  (bsc#1092949)

  - 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-2018-8905: Prevent heap-based buffer overflow in the function
  LZWDecodeCompat via a crafted TIFF file (bsc#1086408)

  - 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)
