CVE ID : CVE-2019-7282 CVE-2019-7283

Two issues have been found in netkit-rsh, client and server programs for
remote shell connections.
Due to insufficient input validation in path names sent by server, a
malicious server can do arbitrary file overwrites in the target directory
or modify permissions of the target directory.
