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

  - 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 0.71.0. 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
    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)

Note that Tenable Network Security has extracted the preceding
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.");
