The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200404-05
(ipsec-tools contains an X.509 certificates vulnerability.)
racoon (a utility in the ipsec-tools package) does not verify digital
signatures on Phase1 packets. This means that anybody holding the correct
X.509 certificate would be able to establish a connection, even if they did
not have the corresponding private key.
Since digital signatures are not verified by the racoon tool, an attacker may
be able to connect to the VPN gateway and/or execute a man-in-the-middle attack.
A workaround is not currently known for this issue. All users are advised
to upgrade to the latest version of the affected package.
