25 Sep 2018 — In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data in the digestAlgorithm.parameters field during PKCS#1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication. This is a variant of CVE-2006-4790 and CVE-2014-1568.

17 Jun 2018 — strongSwan 5.6.0 and older allows Remote Denial of Service because of Missing Initialization of a Variable. strongSwan, en versiones 5.6.0 y anteriores, permite una denegación de servicio (DoS) remota debido a la falta de inicialización de una variable. It was discovered that strongSwan incorrectly handled IKEv2 key derivation. A remote attacker could possibly use this issue to cause strongSwan to crash, resulting in a denial of service.

31 May 2018 — In stroke_socket.c in strongSwan before 5.6.3, a missing packet length check could allow a buffer underflow, which may lead to resource exhaustion and denial of service while reading from the socket. En stroke_socket.c en strongSwan en versiones anteriores a la 5.6.3, la ausencia de comprobaciones de la longitud de los paquetes podría permitir un desbordamiento del búfer, lo que puede conducir al agotamiento del recurso y a la denegación de servicio mientras se lee desde el socket.
