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

  - PDFDoc::markObject in PDFDoc.cc in Poppler 0.74.0
    mishandles dict marking, leading to stack consumption
    in the function Dict::find() located at Dict.cc, which
    can (for example) be triggered by passing a crafted pdf
    file to the pdfunite binary.(CVE-2019-9903)

  - 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
    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
    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)

  - 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)

  - 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)

  - An issue was discovered in Poppler 0.74.0. There is a
    heap-based buffer over-read in the function
    PSOutputDev::checkPageSlice at
    PSOutputDev.cc.(CVE-2019-10871)

  - 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)

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.");
