"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).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
