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.
