Se ha detectado un fallo en OpenSSH. Con la autenticación GSSAPI habilitada, un intento fallido de GSSAPI puede dejar almacenadas para la conexión las credenciales delegadas, aunque la autorización del usuario no haya tenido éxito. Un inicio de sesión posterior exitoso en esa conexión no queda autorizado por el estado residual.
