  "details" : [ "An issue was discovered in Libreswan before 4.12. When an IKEv1 Quick Mode connection configured with ID_IPV4_ADDR or ID_IPV6_ADDR receives an IDcr payload with ID_FQDN, a NULL pointer dereference causes a crash and restart of the pluto daemon. NOTE: the earliest affected version is 4.6.", "A NULL pointer dereference flaw was found in Libreswan when processing IKEv1 Quick Mode requests. When an IKEv1 Quick Mode connection configured with ID_IPV4_ADDR or ID_IPV6_ADDR receives an IDcr payload with ID_FQDN, it triggers a NULL pointer dereference error. This flaw allows a malicious client or attacker to send a malformed IKEv1 Quick Mode packet, causing a crash and restart of the libreswan pluto daemon. When sent continuously, this issue leads to a denial of service attack." ],
