Description
Routinator runs out of open connections on the HTTP server when many connections are opened but never closed, leaving the HTTP server unavailable. This condition can be triggered maliciously by an attacker by opening a large number of connections to the HTTP server.
This only affects users that make their HTTP or RTR server available to untrusted networks.
