The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201603-13
(Libreswan: Multiple Vulnerabilities)
The pluto IKE daemon in Libreswan, when built with NSS, allows remote
attackers to cause a Denial of Service (assertion failure and daemon
restart) via a zero DH g^x value in a KE payload in a IKE packet.
Additionally, remote attackers could cause a Denial of Service (daemon
restart) via an IKEv1 packet with (1) unassigned bits set in the IPSEC
DOI value or (2) the next payload value set to ISAKMP_NEXT_SAK.
Remote attackers could possibly cause Denial of Service.
There is no known workaround at this time.
