Add replay protection DoS vulnerability fix #85

Closed RandyGaul closed 5 years ago

RandyGaul commented 5 years ago

Fixes a vulnerability where players can potentially be DoS'd by packets crafted with large sequence numbers. The fix simply separates replay protection into a read only part (the culling part), and a track and write max sequence part that happens after a successful decryption.
