The ASN.1 parser in strongSwan before 5.5.3 improperly handles CHOICE types when the x509 plugin is enabled, which allows remote attackers to cause a denial of service (infinite loop) via a crafted certificate. El analizador ASN.1 en strongSwan anterior a versión 5.5.3, maneja inapropiadamente los tipos CHOICE cuando el plugin x509 está habilitado, lo que permite a los atacantes remotos causar una denegación de servicio (bucle infinito) por medio de un certificado diseñado. • http://www.debian.org/security/2017/dsa-3866 http://www.securityfocus.com/bid/98756 http://www.ubuntu.com/usn/USN-3301-1 https://www.strongswan.org/blog/2017/05/30/strongswan-vulnerability-%28cve-2017-9023%29.html • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

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 •

https://notcve.org/view.php?id=CVE-2013-5018
The is_asn1 function in strongSwan 4.1.11 through 5.0.4 does not properly validate the return value of the asn1_length function, which allows remote attackers to cause a denial of service (segmentation fault) via a (1) XAuth username, (2) EAP identity, or (3) PEM encoded file that starts with a 0x04, 0x30, or 0x31 character followed by an ASN.1 length value that triggers an integer overflow. La función is_asn1 en strongSwan v4.1.11 hasta v5.0.4 no valida correctamente el valor de retorno de la función asn1_length, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria) a través de (1) nombre de usuario XAuth, (2) identidad EAP, o (3) la codificación PEM de un fichero que comienza con los caracteres "0x04, 0x30, o 0x31" seguidos por un valor de tamaño ASN.1 que dispara un desbordamiento de enteros. • http://lists.opensuse.org/opensuse-updates/2013-08/msg00021.html http://lists.opensuse.org/opensuse-updates/2013-08/msg00022.html http://lists.opensuse.org/opensuse-updates/2013-08/msg00050.html http://secunia.com/advisories/54315 http://secunia.com/advisories/54524 http://strongswan.org/blog/2013/08/01/strongswan-5.1.0-released.html http://strongswan.org/blog/2013/08/01/strongswan-denial-of-service-vulnerability-%28cve-2013-5018%29.html http://www.securityfocus.com/bid/61564 https& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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. NOTA: esta podría ser la misma vulnerabilidad que CVE-2013-2053 y CVE-2013-2054. • http://download.strongswan.org/security/CVE-2013-2054/CVE-2013-2054.txt http://www.securityfocus.com/bid/59837 https://lists.libreswan.org/pipermail/swan-announce/2013/000003.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
