"According to the version of the gcc packages installed, the EulerOS
Virtualization installation on the remote host is affected by the
following vulnerability :

  - The std::random_device class in libstdc++ in the GNU
    Compiler Collection (aka GCC) before 4.9.4 does not
    properly handle short reads from blocking sources,
    which makes it easier for context-dependent attackers
    to predict the random values via unspecified
    vectors.(CVE-2015-5276)

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.");
