"According to the versions of the perl packages installed, the EulerOS
Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerabilities :

  - The XSLoader::load method in XSLoader in Perl does not
    properly locate .so files when called in a string eval,
    which might allow local users to execute arbitrary code
    via a Trojan horse library under the current working
    directory.(CVE-2016-6185)

  - 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.");
