Description Patrick Del Bello 2022-10-05 18:15:54 UTC 
Because the revocation plugin uses potentially untrusted OCSP URIs and CRL distribution points (CDP) in certificates, a remote attacker is able 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.  Affected are all strongSwan versions if they use the revocation plugin or a custom plugin that implements similar features.
