The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200804-03
(OpenSSH: Privilege escalation)
Two issues have been discovered in OpenSSH:
Lindfors discovered that OpenSSH sets the DISPLAY variable in SSH
sessions using X11 forwarding even when it cannot bind the X11 server
to a local port in all address families (CVE-2008-1483).
OpenSSH will execute the contents of the '.ssh/rc' file even when
the 'ForceCommand' directive is enabled in the global sshd_config
A local attacker could exploit the first vulnerability to hijack
forwarded X11 sessions of other users and possibly execute code with
their privileges, disclose sensitive data or cause a Denial of Service,
by binding a local X11 server to a port using only one address family.
The second vulnerability might allow local attackers to bypass intended
security restrictions and execute commands other than those specified
by 'ForceCommand' if they are able to write to their home directory.
There is no known workaround at this time.
