Summary
strongswan vulnerability
Details

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.
