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

Medium Nessus Plugin ID 110274

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

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.

Solution

Update the affected package.
