The remote SSH service may be affected by an X11 forwarding port
According to its banner, the version of SSH installed on the remote
host is older than 5.1 and may allow a local user to hijack the X11
forwarding port. The application improperly sets the 'SO_REUSEADDR'
socket option when the 'X11UseLocalhost' configuration option is
Note that most operating systems, when attempting to bind to a port
that has previously been bound with the 'SO_REUSEADDR' option, will
check that either the effective user-id matches the previous bind
(common BSD-derived systems) or that the bind addresses do not overlap
(Linux and Solaris). This is not the case with other operating
systems such as HP-UX.
