The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200909-05
(Openswan: Denial of Service)
Multiple vulnerabilities have been discovered in Openswan:
Gerd v. Egidy reported a NULL pointer dereference in the Dead Peer
Detection of the pluto IKE daemon as included in Openswan
The Orange Labs vulnerability research team
discovered multiple vulnerabilities in the ASN.1 parser
A remote attacker could exploit these vulnerabilities by sending
specially crafted R_U_THERE or R_U_THERE_ACK packets, or a specially
crafted X.509 certificate containing a malicious Relative Distinguished
Name (RDN), UTCTIME string or GENERALIZEDTIME string to cause a Denial
of Service of the pluto IKE daemon.
There is no known workaround at this time.
