In verify_signed_hash() in lib/liboswkeys/signatures.c in Openswan before 2.6.50.1, the RSA implementation does not verify the value of padding string during PKCS#1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used. IKEv2 signature verification is affected when RAW RSA keys are used. En Openswan en versiones anteriores a la 2.6.50.1, la verificación de firmas IKEv2 es vulnerable a "variantes de ataques de bajo exponente de Bleichenbacher en firmas RSA PKCS#1" cuando se emplean claves RSA RAW. • https://github.com/xelerance/Openswan/commit/0b460be9e287fd335c8ce58129c67bf06065ef51 https://github.com/xelerance/Openswan/commit/9eaa6c2a823c1d2b58913506a15f9474bf857a3d https://lists.openswan.org/pipermail/users/2018-August/023761.html • CWE-347: Improper Verification of Cryptographic Signature •

Openswan 2.6.39 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon restart) via IKEv2 packets that lack expected payloads. Openswan v2.6.39 y anteriores permite a atacantes remotos provocar una denegación de servicio (referencia a puntero nulo y reinicio del demonio IKE) a través de paquetes IKEv2 que cuenten con payloads esperados. • http://rhn.redhat.com/errata/RHSA-2014-0185.html http://www.debian.org/security/2014/dsa-2893 http://www.securityfocus.com/bid/65155 https://cert.vde.com/en-us/advisories/vde-2017-001 https://exchange.xforce.ibmcloud.com/vulnerabilities/90524 https://libreswan.org/security/CVE-2013-6467/CVE-2013-6467.txt https://access.redhat.com/security/cve/CVE-2013-6466 https://bugzilla.redhat.com/show_bug.cgi?id=1050277 •

Buffer overflow in the atodn function in Openswan before 2.6.39, 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-2013-2052 and CVE-2013-2054. Desbordamiento de buffer en la función atodn en Openswan anteriores a v2.6.39, cuando está activada Opportunistic Encryptiony se usa una clave RSA, permite a los atacantes remotos provocar una denegación de servicio (caída del demonio IKE)y posiblemente ejecutar código a través de registros DNS TXT. Nota: esta podría ser la misma vulnerabilidad que CVE-2013-2052 y CVE-2013-2054. • http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00008.html http://rhn.redhat.com/errata/RHSA-2013-0827.html http://www.debian.org/security/2014/dsa-2893 http://www.securityfocus.com/bid/59838 https://bugzilla.redhat.com/show_bug.cgi?id=960229 https://lists.libreswan.org/pipermail/swan-announce/2013/000003.html https://www.openswan.org/news/13 https://access.redhat.com/security/cve/CVE-2013-2053 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
