rssh (2.3.4-5+deb9u1) stretch-security; urgency=high
scp and rsync command verification have been made stricter to try to
prevent ways of running arbitrary code on the server via ssh
configuration options. As a side effect, this will break scp -3 to an
account using rssh, and will disallow using rssh to run arbitrary scp
and rsync commands on the server. Only the server end of an scp or
rsync command should now be allowed.
THE CVS SUPPORT IN RSSH IS PROBABLY NOT SECURE, as is already documented
in the manual page. While no variation of this attack for cvs is
currently known, cvs has many options and commands and the small amount
of filtering rssh does is probably not sufficient. Use the cvs support
at your own risk.
The approach rssh takes to try to restrict commands is fragile,
regularly broken by new features in the commands it tries to wrap, and
probably has additional bugs. It is no longer supported upstream and
will likely be removed from future versions of Debian. Please consider
switching to another security approach.
