Vulnerability Discussion

Unowned files and directories may be unintentionally inherited if a user is assigned the same User Identifier (UID) as the UID of the unowned files.

Check

Verify that all SUSE operating system files and directories on the system have a valid owner.

Check the owner of all files and directories with the following command:

Note: The value after -fstype must be replaced with the filesystem type. XFS is used as an example.

> sudo find / -fstype xfs -nouser

If any files on the system do not have an assigned owner, this is a finding.

Fix

Either remove all files and directories from the SUSE operating system that do not have a valid user, or assign a valid user to all unowned files and directories on the system with the "chown" command:

> sudo chown
