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

  - A stack-based buffer overflow was found in the poppler
    library. An attacker could create a malicious PDF file
    that would cause applications that use poppler (such as
    Evince) to crash, or potentially execute arbitrary code
    when opened. (CVE-2017-9775)

  - An integer overflow leading to heap-based buffer
    overflow was found in the poppler library. An attacker
    could create a malicious PDF file that would cause
    applications that use poppler (such as Evince) to
    crash, or potentially execute arbitrary code when
    opened. (CVE-2017-9776)

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.");
