Description Laura Pardo 2019-02-04 19:47:37 UTC
A flaw was found in rssh. The client could send the --daemon and --config options to the server and they would be passed through by rssh.  Not only does this allow the client to start a daemon listening on the normal rsync port, which is probably not desirable, but various options set in the daemon configuration file specified with --config allow arbitrary code execution.  (The most obvious is pre-xfer exec.)
