Descriptions

An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6. Direct dereference of a NULL pointer (a variable initialized to NULL) leads to a crash when validating the certificate of a client connecting to the server in a TLS client/server mutual-authentication setup.

Se detectó un problema en la función tls_verify_crl en ProFTPD versiones anteriores a 1.3.6. Una desreferencia directa de un puntero NULL (una variable inicializada en NULL) conlleva a un bloqueo al comprobar el certificado de un cliente que se conecta al servidor en una configuración de autenticación mutua cliente/servidor TLS.
