CVE-ID: CVE-2019-12312
CVE-Crit: HIGH
CVE-DESC: In Libreswan 3.27, an assertion failure can cause the IKE pluto daemon to restart. An attacker can initiate a NULL pointer dereference by initiating an IKEv2 IKE_SA_INIT exchange followed by a dummy INFORMATIONAL exchange instead of the normally expected IKE_AUTH exchange. This affects send_v2N_spi_response_from_state () in / pluto / ikev2_send.c programs, which will then cause the NULL pointer to be dereferenced, causing libreswan to restart.
