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 •

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.
