Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side.
