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') •

The gmp plugin in strongSwan before 5.5.3 does not properly validate RSA public keys before calling mpz_powm_sec, which allows remote peers to cause a denial of service (floating point exception and process crash) via a crafted certificate. El plugin gmp en strnogSwan anterior a 5.5.3 no valida adecuadamente las claves públicas RSA tras la llamada mpz_powm_sec, lo que podría permitir a peers remotos causar una denegación de servicio (excepción de punto flotante y cierre inesperado del proceso) a través de un certificado especialmente diseñado. • http://www.debian.org/security/2017/dsa-3866 http://www.securityfocus.com/bid/98760 http://www.ubuntu.com/usn/USN-3301-1 https://www.strongswan.org/blog/2017/05/30/strongswan-vulnerability-%28cve-2017-9022%29.html • CWE-20: Improper Input Validation •

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 •

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 •
