"According to the versions of the poppler packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - In Poppler 0.59.0, a NULL Pointer Dereference exists in
    the XRef::parseEntry() function in XRef.cc via a
    crafted PDF document.(CVE-2017-14517)

  - In Poppler 0.59.0, a floating point exception exists in
    the isImageInterpolationRequired() function in
    Splash.cc via a crafted PDF document.(CVE-2017-14518)

  - In Poppler 0.59.0, memory corruption occurs in a call
    to Object::streamGetChar in Object.h after a repeating
    series of Gfx::display, Gfx::go, Gfx::execOp,
    Gfx::opShowText, and Gfx::doShowText calls (aka a
    Gfx.cc infinite loop).(CVE-2017-14519)

  - In Poppler 0.59.0, a floating point exception occurs in
    Splash::scaleImageYuXd() in Splash.cc, which may lead
    to a potential attack when handling malicious PDF
    files.(CVE-2017-14520)

  - In Poppler 0.59.0, a floating point exception occurs in
    the ImageStream class in Stream.cc, which may lead to a
    potential attack when handling malicious PDF
    files.(CVE-2017-14617)

  - In Poppler 0.59.0, memory corruption occurs in a call
    to Object::dictLookup() in Object.h after a repeating
    series of Gfx::display, Gfx::go, Gfx::execOp,
    Gfx::opFill, Gfx::doPatternFill,
    Gfx::doTilingPatternFill and Gfx::drawForm calls (aka a
    Gfx.cc infinite loop), a different vulnerability than
    CVE-2017-14519.(CVE-2017-14929)

  - The FoFiTrueType::getCFFBlock function in
    FoFiTrueType.cc in Poppler 0.59.0 has a NULL pointer
    dereference vulnerability due to lack of validation of
    a table pointer, which allows an attacker to launch a
    denial of service attack.(CVE-2017-14977)

  - The FoFiType1C::convertToType0 function in
    FoFiType1C.cc in Poppler 0.59.0 has a heap-based buffer
    over-read vulnerability if an out-of-bounds font
    dictionary index is encountered, which allows an
    attacker to launch a denial of service
    attack.(CVE-2017-14976)

  - The FoFiType1C::convertToType0 function in
    FoFiType1C.cc in Poppler 0.59.0 has a NULL pointer
    dereference vulnerability because a data structure is
    not initialized, which allows an attacker to launch a
    denial of service attack.(CVE-2017-14975)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
