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

  - An information disclosure vulnerability was discovered
    in glusterfs server. An attacker could issue a xattr
    request via glusterfs FUSE to determine the existence
    of any file.(CVE-2018-10913)

  - It was found that an attacker could issue a xattr
    request via glusterfs FUSE to cause gluster brick
    process to crash which will result in a remote denial
    of service. If gluster multiplexing is enabled this
    will result in a crash of multiple bricks and gluster
    volumes.(CVE-2018-10914)

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.");
