Libreswan 4.2 through 4.5 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted IKEv1 packet because pluto/ikev1.c wrongly expects that a state object exists. This is fixed in 4.6.
The product dereferences a pointer that it expects to be valid but is NULL.
