Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

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.

Impact :

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.

Workaround :

A workaround is not currently known for this issue. All users are advised
to upgrade to the latest version of the affected package.
