"According to the version of the perl-Data-Dumper package installed,
the EulerOS Virtualization installation on the remote host is
affected by the following vulnerability :

  - The Dumper method in Data::Dumper before 2.154, as used
    in Perl 5.20.1 and earlier, allows context-dependent
    attackers to cause a denial of service (stack
    consumption and crash) via an Array-Reference with many
    nested Array-References, which triggers a large number
    of recursive calls to the DD_dump
    function.(CVE-2014-4330)

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.");
