Summary
USN-5651-1 fixed a vulnerability in strongSwan. This update provides
the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.
Original advisory 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.
