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

  - An issue was discovered in Poppler 0.74.0. There is a
    heap-based buffer over-read in the function
    Splash::blitTransparent at
    splash/Splash.cc.(CVE-2019-10872)

  - 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 through 0.76.1, there is a heap-based buffer
    over-read in JPXStream::init in JPEG2000Stream.cc via
    data with inconsistent heights or
    widths.(CVE-2019-12293)

  - 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)

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.");
