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.
