"This update for poppler fixes the following issues :

  - CVE-2017-14977: Fixed a NULL pointer dereference
    vulnerability in the FoFiTrueType::getCFFBlock()
    function in FoFiTrueType.cc that occurred due to lack of
    validation of a table pointer, which allows an attacker
    to launch a denial of service attack. (bsc#1061265)

  - CVE-2017-1000456: Validate boundaries in
    TextPool::addWord to prevent overflows in subsequent
    calculations (bsc#1074453)

  - CVE-2017-15565: Prevent NULL pointer dereference in the
    GfxImageColorMap::getGrayLine() function via a crafted
    PDF document (bsc#1064593)

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."
