(rssh, scponly: Unrestricted command execution)

    Jason Wies discovered that when receiving an authorized command from an
    authorized user, rssh and scponly do not filter command-line options
    that can be used to execute any command on the target host.
  
Impact :

    Using a malicious command, it is possible for a remote authenticated
    user to execute any command (or upload and execute any file) on the
    target machine with user rights, effectively bypassing any restriction
    of scponly or rssh.
  
Workaround :

    There is no known workaround at this time."
