strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data. strongSwan anterior a 5.9.8 permite a atacantes remotos provocar una Denegación de Servicio en el complemento de revocación enviando un certificado de entidad final (y CA intermedia) manipulado que contiene una URL CRL/OCSP que apunta a un servidor (bajo el control del atacante) que no responde adecuadamente pero (por ejemplo) simplemente no hace nada después del protocolo de enlace TCP inicial o envía una cantidad excesiva de datos de la aplicación. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J3GAYIOCSLU57C45CO4UE4IV4JZE4W3L https://www.strongswan.org/blog/2022/10/03/strongswan-vulnerability-%28cve-2022-40617%29.html • CWE-400: Uncontrolled Resource Consumption •
CVSS: 3.5EPSS: 0%CPEs: 6EXPL: 0CVE-2019-10155 – libreswan: vulnerability in the processing of IKEv1 informational packets due to missing integrity check
https://notcve.org/view.php?id=CVE-2019-10155
The Libreswan Project has found a vulnerability in the processing of IKEv1 informational exchange packets which are encrypted and integrity protected using the established IKE SA encryption and integrity keys, but as a receiver, the integrity check value was not verified. This issue affects versions before 3.29. Se ha encontrado una vulnerabilidad en el proyecto The Libreswan en el procesador de IKEv1 Los paquetes de intercambio informativo IKEv1 que están cifrados y protegidos por integridad utilizando las claves de integridad y cifrado IKE SA establecidas, pero como receptor, el valor de verificación de integridad no se verificó. Este problema afecta a las versiones anteriores a 3.29. A vulnerability was found in the Libreswan Project. • https://access.redhat.com/errata/RHSA-2019:3391 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10155 https://libreswan.org/security/CVE-2019-10155 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EUEXFCN7FAYBKJBQJLYCEUQUCHDEJRZW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LFGPGLLKAXSLWFI62A6BZHTZSCHRCBXS https://access.redhat.com/security/cve/CVE-2019-10155 https://bugzilla.redhat.com/show_bug.cgi?id=1714141 • CWE-354: Improper Validation of Integrity Check Value •

In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data after the encoded algorithm OID during PKCS#1 v1.5 signature verification. Similar to the flaw in the same version of strongSwan regarding digestAlgorithm.parameters, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication. En verify_emsa_pkcs1_signature() en gmp_rsa_public_key.c en el plugin gmp en strongSwan en versiones 4.x y 5.x anteriores a la 5.7.0, la implementación RSA basada en GMP no rechaza los datos sobrantes tras el algoritmo OID cifrado durante la verificación de firmas PKCS#1 v1.5. De forma similar al error en la misma versión de strongSwan relacionado con digestAlgorithm.parameters, un atacante remoto puede falsificar firmas cuando se emplean pequeños exponentes públicos, lo que podría conducir a una suplantación cuando solo se emplea una firma RSA para la autenticación IKEv2. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00077.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00047.html https://lists.debian.org/debian-lts-announce/2018/09/msg00032.html https://security.gentoo.org/glsa/201811-16 https://usn.ubuntu.com/3771-1 https://www.debian.org/security/2018/dsa-4305 https://www.strongswan.org/blog/2018/09/24/strongswan-vulnerability-%28cve-20 • CWE-347: Improper Verification of Cryptographic Signature •
