Synopsis :

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

Description :

strongSwan security team reports :

- RSA public keys passed to the gmp plugin aren't validated
sufficiently before attempting signature verification, so that invalid
input might lead to a floating point exception. [CVE-2017-9022]

- ASN.1 CHOICE types are not correctly handled by the ASN.1 parser
when parsing X.509 certificates with extensions that use such types.
This could lead to infinite looping of the thread parsing a
specifically crafted certificate.
