  "summary" : "Symfony2 security issue when the trust proxy mode is enabled",
  "details" : "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.\n\nTo fix this security issue, the following changes have been made to all versions of Symfony2:\n\nA 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:\n```\n// before (probably in your front controller script)\nRequest::trustProxyData();\n\n// after\nRequest::setTrustedProxies(array('1.1.1.1'));\n// 1.1.1.1 being the IP address of a trusted reverse proxy\n```\nThe Request::trustProxyData() method has been deprecated (when used, it automatically trusts the latest proxy in the chain -- which is the current remote address):\n```\nRequest::trustProxyData();\n\n// is equivalent to\nRequest::setTrustedProxies(array($request->server->get('REMOTE_ADDR')));\n```\nWe 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:\n\n- [Patch](https://github.com/symfony/symfony/compare/fc89d6b...9ce892c.patch) for Symfony 2.0.19\n- [Patch](https://github.com/symfony/symfony/compare/922c201...e5536f0.patch) for Symfony 2.1.4",
