Security release: Symfony 2.0.19 and 2.1.4

I've just released Symfony 2.0.19 and 2.1.4. Both releases contain a security fix.
Damien Tournoud, from the Drupal security team, contacted us two days ago about a security issue in the Request::getClientIp()
method when the trust proxy mode is enabled (Request::trustProxyData()
).
An application is vulnerable if it uses the client IP address as returned by the Request::getClientIp()
method for sensitive decisions like IP based access control.
To fix this security issue, the following changes have been made to all versions of Symfony2:
A new Request::setTrustedProxies()
method has been introduced and should be used intead of Request::trustProxyData()
to enable the trust proxy mode. It takes an array of trusted proxy IP addresses as its argument:
// before (probably in your front controller script)
Request::trustProxyData();
// after
Request::setTrustedProxies(array('1.1.1.1'));
// 1.1.1.1 being the IP address of a trusted reverse proxy
The Request::trustProxyData()
method has been deprecated (when used, it automatically trusts the latest proxy in the chain -- which is the current remote address):
Request::trustProxyData();
// is equivalent to
Request::setTrustedProxies(array($request->server->get('REMOTE_ADDR')));
We encourage all Symfony2 users to upgrade as soon as possible. It you don't want to upgrade to the latest version yet, you can also apply the following patches:

Is there any configuration to inject a list of trusted proxies ?
Thanks for keeping Symfony secure!
Thanks for the release. ;)
btw, composer works well at this time.
