Descriptions
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.
