## Description

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.
