| Name | CVE-2016-5361 |
| Description | programs/pluto/ikev1.c in libreswan before 3.17 retransmits in initial-responder states, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed UDP packet. NOTE: the original behavior complies with the IKEv1 protocol, but has a required security update from the libreswan vendor; as of 2016-06-10, it is expected that several other IKEv1 implementations will have vendor-required security updates, with separate CVE IDs assigned to each. |

MITRE has not assigned the CVE to the protocol flaw, but specific to libreswan, but as
Huzaifa Sidhpurwala <huzaifas@redhat.com> pointed out that is not a libreswan issue, rather
the protocol is flawed.
