"The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2019-2022 advisory.

  - 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)

  - 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)

  - A reachable Object::dictLookup assertion in Poppler 0.72.0 allows attackers to cause a denial of service
    due to the lack of a check for the dict data type, as demonstrated by use of the FileSpec class (in
    FileSpec.cc) in pdfdetach. (CVE-2018-20650)

  - In Poppler 0.72.0, PDFDoc::setup in PDFDoc.cc allows attackers to cause a denial-of-service (application
    crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF
    file in which an xref data structure is mishandled during extractPDFSubtype processing. (CVE-2018-20662)

  - 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)

  - A heap-based buffer underwrite exists in ImageStream::getLine() located at Stream.cc in Poppler 0.74.0
    that can (for example) be triggered by sending a crafted PDF file to the pdfimages binary. It allows an
    attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.
    (CVE-2019-9200)

  - Poppler 0.74.0 has a heap-based buffer over-read in the CairoRescaleBox.cc downsample_row_box_filter
    function. (CVE-2019-9631)

  - An issue was discovered in Poppler 0.71.0. There is a reachable abort in Object.h, will lead to denial of
    service because EmbFile::save2 in FileSpec.cc lacks a stream check before saving an embedded file.
    (CVE-2018-19058)

  - An issue was discovered in Poppler 0.71.0. There is a out-of-bounds read in EmbFile::save2 in FileSpec.cc,
    will lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating embedded files before
    save attempts. (CVE-2018-19059)

  - 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)

  - Poppler before 0.70.0 has a NULL pointer dereference in _poppler_attachment_new when called from
    poppler_annot_file_attachment_get_attachment. (CVE-2018-19149)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
