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

  - In Poppler 0.68.0, the Parser::getObj() function in
    Parser.cc may cause infinite recursion via a crafted
    file. A remote attacker can leverage this for a DoS
    attack.(CVE-2018-16646)

  - An issue was discovered in Poppler 0.71.0. There is a
    memory leak in GfxColorSpace::setDisplayProfile in
    GfxState.cc, as demonstrated by
    pdftocairo.(CVE-2018-18897)

  - An issue was discovered in Poppler 0.71.0. There is a
    NULL pointer dereference in goo/GooString.h, will lead
    to denial of service, as demonstrated by
    utils/pdfdetach.cc not validating a filename of an
    embedded file before constructing a save
    path.(CVE-2018-19060)

  - XRef::getEntry in XRef.cc in Poppler 0.72.0 mishandles
    unallocated XRef entries, which allows remote attackers
    to cause a denial of service (NULL pointer dereference)
    via a crafted PDF document, when XRefEntry::setFlag in
    XRef.h is called from Parser::makeStream in
    Parser.cc.(CVE-2018-20481)

  - An issue was discovered in Poppler through 0.78.0.
    There is a divide-by-zero error in the function
    SplashOutputDev::tilingPatternFill at
    SplashOutputDev.cc.(CVE-2019-14494)

  - In Poppler 0.73.0, a heap-based buffer over-read (due
    to an integer signedness error in the XRef::getEntry
    function in XRef.cc) allows remote attackers to cause a
    denial of service (application crash) or possibly have
    unspecified other impact via a crafted PDF document, as
    demonstrated by pdftocairo.(CVE-2019-7310)
