CVE-2016-4423: Large username storage in session The attemptAuthentication function in `Component/Security/Http/Firewall/UsernamePasswordFormAuthenticationListener.php` does not limit the length of a username stored in a session, which allows remote attackers to cause a denial of service (session storage consumption) via a series of authentication attempts with long, non-existent usernames.

CVE-2015-2309
GHSA-p684-f7fh-jv2j
Unsafe methods in the Request class The `Symfony\Component\HttpFoundation\Request` class provides a mechanism that ensures it does not trust HTTP header values coming from a "non-trusted" client. Unfortunately, it assumes that the remote address is always a trusted client if at least one trusted proxy is involved in the request; this allows a man-in-the-middle attack between the latest trusted proxy and the web server. The following methods are impacted: `getPort()`, `isSecure()`, `getHost()` and `getClientIps()`.
