The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2806 advisory.

    Multiple security vulnerabilities were discovered in GlusterFS, a clustered file system. Buffer overflows     and path traversal issues may lead to information disclosure, denial-of-service or the execution of     arbitrary code. For Debian 9 stretch, these problems have been fixed in version 3.8.8-1+deb9u1. We     recommend that you upgrade your glusterfs packages. For the detailed security status of glusterfs please     refer to its security tracker page at: https://security-tracker.debian.org/tracker/glusterfs Further     information about Debian LTS security advisories, how to apply these updates to your system and frequently     asked questions can be found at: https://wiki.debian.org/LTS

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)
