FreeBSD: VID-7fc3e827-64a5-11e8-aedb-00224d821998 (CVE-2018-10811): strongswan -- Fix Denial-of-Service Vulnerability strongSwan (CVE-2018-10811, CVE-2018-5388)

strongSwan security team reports: A denial-of-service vulnerability in the IKEv2 key derivation was fixed if the openssl plugin is used in FIPS mode and HMAC-MD5 is negotiated as PRF (which is not FIPS-compliant). So this should only affect very specific setups, but in such configurations all strongSwan versions since 5.0.1 may be affected. A denial-of-service vulnerability in the stroke plugin was fixed. When reading a message from the socket the plugin did not check the received length. Unless a group is configured, root privileges are required to access that socket, so in the default configuration this shouldn't be an issue, but all strongSwan versions may be affected.
