"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)
