CVE-2015-3240
The pluto IKE daemon in libreswan before 3.15 and Openswan before 2.6.45, when built with NSS, allows remote attackers to cause a denial of service (assertion failure and daemon restart) via a zero DH g^x value in a KE payload in a IKE packet.

Does this matter?
Lower severity and a low EPSS score (2.77%). Track it; it rarely justifies an emergency change on its own.
