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

  - A privilege escalation flaw was found in gluster
    snapshot scheduler. Any gluster client allowed to mount
    gluster volumes could also mount shared gluster storage
    volume and escalate privileges by scheduling malicious
    cronjob via symlink.(CVE-2018-1088)

  - It was found that fix for CVE-2018-1088 introduced a
    new vulnerability in the way 'auth.allow' is
    implemented in glusterfs server. An unauthenticated
    gluster client could mount gluster storage
    volumes.(CVE-2018-1112)

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.");
