strongSwan before 5.1.2 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon crash) via a crafted ID_DER_ASN1_DN ID payload. strongSwan en versiones anteriores a 5.1.2 permite a atacantes remotos provocar una denegación de servicio (referencia a puntero null y una caída del demonio IKE) a través de un payload IDER_ASN1_DN ID manipulado. • http://lists.opensuse.org/opensuse-updates/2014-05/msg00064.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00066.html http://secunia.com/advisories/59864 http://www.debian.org/security/2014/dsa-2922 http://www.securityfocus.com/bid/67212 http://www.strongswan.org/blog/2014/05/05/strongswan-denial-of-service-vulnerability-%28cve-2014-2891%29.html •

IKEv2 in strongSwan 4.0.7 before 5.1.3 allows remote attackers to bypass authentication by rekeying an IKE_SA during (1) initiation or (2) re-authentication, which triggers the IKE_SA state to be set to established. IKEv2 en strongSwan 4.0.7 anterior a 5.1.3 permite a atacantes remotos evadir autenticación mediante la recodificación de un IKE_SA durante (1) iniciación o (2) re-autenticación, lo que provoca el estado de IKE_SA sea configurado como establecido. • http://lists.opensuse.org/opensuse-security-announce/2014-04/msg00010.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00064.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00066.html http://secunia.com/advisories/57823 http://www.debian.org/security/2014/dsa-2903 http://www.securityfocus.com/bid/66815 http://www.strongswan.org/blog/2014/04/14/strongswan-authentication-bypass-vulnerability-%28cve-2014-2338%29.html • CWE-287: Improper Authentication •

Buffer overflow in the atodn function in strongSwan 2.0.0 through 4.3.4, when Opportunistic Encryption is enabled and an RSA key is being used, allows remote attackers to cause a denial of service (pluto IKE daemon crash) and possibly execute arbitrary code via crafted DNS TXT records. NOTE: this might be the same vulnerability as CVE-2013-2053 and CVE-2013-2054. Desbordamiento de buffer en la función atodn en strongSwan v2.0.0 hasta v4.3.4, cuando está activada "Opportunistic Encryption" y se usa una clave RSA, permite a atacantes remotos provocar una denegación de servicio (caida del demonio IKE) y posiblemente ejecutar código a través de registros DNS TXT.

The asn1_length function in strongSwan 2.8 before 2.8.11, 4.2 before 4.2.17, and 4.3 before 4.3.3 does not properly handle X.509 certificates with crafted Relative Distinguished Names (RDNs), which allows remote attackers to cause a denial of service (pluto IKE daemon crash) via malformed ASN.1 data. NOTE: this is due to an incomplete fix for CVE-2009-2185. La función asn1_length en strongSwan 2.8 antes de 2.8.11, 4.2 antes de 4.2.17 y 4.3 antes de 4.3.3 no maneja adecuadamente certificados X.509 con Relative Distinguished Names (RDNs) modificados, lo que permite a atacantes remotos provocar una denegación de servicio (caída del demonio pluto IKE) mediante datos ASN.1 malformados.
