I have a TW/KDE system which prior to the very recent very large update I have noticed a change in the properties of any SMB mount, where as before they would be accessible from my user they now have user and group set to root for all directories which means I am unable to easily copy from my files to a directory on the SMB mounted directory. I am by the way using SMB4K to do the mounting.
Is this perhaps a result of the fix for the recently detected vunerablility or a new bug?
These are not permanent mounts vis the fstab but each one is done when needed via SMB4K. Prior to this very large update it worked fine, now something has changed so any mount done by SMB4K now sets all directories on the remote file system to root.
While you might find a usable by-pass (or even a a definitive solution) for your case, to me this looks like something worth a bug report. It worked as intended until a certain update.
