Libreswan and Heartbleed

Is Libreswan vulnerable to the OpenSSL "Heartbleed" exploit?

Libreswan is NOT vulnerable to the openssl vulnerability CVE-2014-0160 known as Heartbleed.

Libreswan is an implementation of IPsec IKEv1 and IKEv2 keying protocols. These protocols do not use TLS to establish VPN connections. VPN services and products based on TLS are often called "SSL VPNs". Libreswan is an IKE/IPsec based VPN.

Libreswan does not use openssl for IKE/IPsec. Libreswan does use libcurl which itself uses openssl for establishing connections for OCSP and CRL URLs, but it does not provide a server for OCSP/CRL and is therefor not vulnerable there either.
