FreeBSD : strongSwan -- ECDSA signature verification issue (6ff570cb-b418-11e2-b279-20cf30e32f6d)

Medium Nessus Plugin ID 66312


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


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.


Update the affected package.
