netty-codec-haproxy: Netty-codec-haproxy: Denial of Service via malformed HAProxy message

A flaw was found in netty-codec-haproxy, a component of the Netty network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy message with a malformed PP2TYPESSL TLV Type-Length-Value header. This can lead to an IndexOutOfBoundsException...
