high Nessus Plugin ID 141672

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.(CVE-2018-6954)

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.

Solution
