Doc Text:	A flaw was found in Libreswan. This issue causes Libreswan to restart under some IKEv2 retransmit scenarios when a connection is configured to use PreSharedKeys (authby=secret), and the connection cannot find a matching configured secret. When automatically added on startup using the auto= keyword, it can cause repeated crashes, leading to a denial of service.	Story Points:	---

Description Avinash Hanwate 2024-03-11 05:44:19 UTC

When an IKEv2 state would fail to find its own PreSharedKey (secret) to create the AUTH payload in the IKE_AUTH Exchange, it would omit sending a packet, but would not delete the state. When this state is referenced later, it would cause an assertion failure and crash and restart the pluto daemon.
