Lahav Schlesinger discovered that strongSwan incorrectly handled certain OCSP URIs and
and CRL distribution points (CDP) in certificates. A remote attacker could
possibly use this issue to initiate IKE_SAs and send crafted certificates
that contain URIs pointing to servers under their control, which can lead
to a denial-of-service attack.
