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

  - The nss_dns implementation of getnetbyname in GNU C     Library (aka glibc) before 2.21, when the DNS backend     in the Name Service Switch configuration is enabled,     allows remote attackers to cause a denial of service     (infinite loop) by sending a positive answer while a     network name is being process.(CVE-2014-9402)

  - A stack overflow vulnerability was found in
    _nss_dns_getnetbyname_r.On systems with nsswitch     configured to include 'networks: dns' with a privileged     or network-facing service that would attempt to resolve     user-provided network names, an attacker could provide     an excessively long network name, resulting in stack     corruption and code execution.(CVE-2016-3075)

  - stdlib/canonicalize.c in the GNU C Library (aka glibc     or libc6) 2.27 and earlier, when processing very long     pathname arguments to the realpath function, could     encounter an integer overflow on 32-bit architectures,     leading to a stack-based buffer overflow and,     potentially, arbitrary code execution.(CVE-2018-11236)

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.
