No affected components available
Zend\Session\Validator\RemoteAddr and Zend\View\Helper\ServerUrl were found to be improperly parsing HTTP headers for proxy information, which could potentially allow an attacker to spoof a proxied IP or host name.
In Zend\Session\Validator\RemoteAddr, if the client is behind a proxy server, the detection of the proxy URL was incorrect, and could lead to invalid results on subsequent lookups.
In Zend\View\Helper\ServerUrl, if the server lives behind a proxy, the helper would always generate a URL based on the proxy host, regardless of whether or not this was desired; additionally, it did not take into account the proxy port or protocol, if provided.
