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

  - An incorrect permission check in the admin backend in     gvfs before version 1.39.4 was found that allows     reading and modify arbitrary files by privileged users     without asking for password when no authentication     agent is running. This vulnerability can be exploited     by malicious programs running under privileges of users     belonging to the wheel group to further escalate its     privileges by modifying system files without user's     knowledge. Successful exploitation requires uncommon     system configuration.(CVE-2019-3827)
