  <description>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).
