"This update for tiff fixes the following issues: 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)
