https://notcve.org/view.php?id=CVE-2022-40617
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 •
