high Nessus Plugin ID 130865

Synopsis

The remote EulerOS host is missing a security update.

Description

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)

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.
