The Eclipse Jetty servlet container vulnerability is related to the fact that an established HTTP/2 SSL connection and a
overloaded TCP will reload when the set time expires. Exploitation of the vulnerability
could allow an attacker acting remotely to cause a state where a server could run out of a
file descriptor, eventually causing the server to stop accepting new
connections from valid clients.
