Security update for tiff (moderate)

This update for tiff fixes the following security issues:

These security issues were fixed:

• CVE-2017-18013: Fixed a NULL pointer dereference in the
  tif_print.cTIFFPrintDirectory function that could have lead to denial of
  service (bsc#1074317).
• CVE-2018-10963: Fixed an assertion failure in the
  TIFFWriteDirectorySec() function in tif_dirwrite.c, which allowed remote
  attackers to cause a denial
  of service via a crafted file (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).
