| Doc Text: |
A flaw was found in Netty. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by exhausting server memory. Because the SPDY session handler does not restrict the number of concurrent streams initiated by a remote peer, an attacker can transmit an excessive volume of stream creation requests over a connection, triggering memory exhaustion and crashing the application.
