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 (CVE-2009-0790).
The Orange Labs vulnerability research team discovered multiple vulnerabilities in the ASN.1 parser (CVE-2009-2185).
Impact :
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.
Workaround :
There is no known workaround at this time.
