https://notcve.org/view.php?id=CVE-2018-15836
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 •

https://notcve.org/view.php?id=CVE-2013-6466
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 •
CVSS: 7.6EPSS: 7%CPEs: 38EXPL: 0CVE-2013-2053 – Openswan: remote buffer overflow in atodn()
https://notcve.org/view.php?id=CVE-2013-2053
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 •

https://notcve.org/view.php?id=CVE-2008-4190
The IPSEC livetest tool in Openswan 2.4.12 and earlier, and 2.6.x through 2.6.16, allows local users to overwrite arbitrary files and execute arbitrary code via a symlink attack on the (1) ipseclive.conn and (2) ipsec.olts.remote.log temporary files. NOTE: in many distributions and the upstream version, this tool has been disabled. La herramienta livetest de IPSEC en Openswan versión 2.4.12 y anteriores, y versiones 2.6.x hasta 2.6.16, permite a los usuarios locales sobrescribir archivos arbitrarios y ejecutar código arbitrario mediante un ataque de tipo symlink en los archivos temporales (1) ipseclive.conn y (2) ipsec.olts.remote.log. NOTA: en muchas distribuciones y en la versión anterior, esta herramienta se ha deshabilitado. Openswan versions equal to and below 2.4.12/2.6.16 suffer from an insecure file creation vulnerability that allows for privilege escalation. • https://www.exploit-db.com/exploits/9135 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=496374 http://dev.gentoo.org/~rbu/security/debiantemp/openswan http://secunia.com/advisories/34182 http://secunia.com/advisories/34472 http://www.debian.org/security/2009/dsa-1760 http://www.openwall.com/lists/oss-security/2008/10/30/2 http://www.redhat.com/support/errata/RHSA-2009-0402.html http://www.securityfocus.com/archive/1/501624/100/0/threaded http://www.securi • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
