Synopsis :

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

Description :

strongSwan security team reports :

If the openssl plugin is used for ECDSA signature verification an
empty, zeroed or otherwise invalid signature is handled as a
legitimate one. Both IKEv1 and IKEv2 are affected.

Affected are only installations that have enabled and loaded the
OpenSSL crypto backend (--enable-openssl). Builds using the default
crypto backends are not affected.
