Description

 - In Libreswan 3.27 an assertion failure can lead to a pluto IKE daemon restart. An attacker can trigger a
 NULL pointer dereference by initiating an IKEv2 IKE_SA_INIT exchange, followed by a bogus INFORMATIONAL
 exchange instead of the normallly expected IKE_AUTH exchange. This affects

 dereference leading to a restart of libreswan. (CVE-2019-12312)
