Debian LTS: DLA-2822-1: netkit-rsh security update
Summary
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.
For Debian 9 stretch, these problems have been fixed in version
0.17-17+deb9u1.
We recommend that you upgrade your netkit-rsh packages.
For the detailed security status of netkit-rsh please refer to
