This can be exploited to cause a system to stop responding to new requests by flooding it using specially crafted packets with a TCP receive window size set to a very small value or zero. SOLUTION: According to the vendor, no patches will be made available as it would require re-architecting a significant amount of the OS. PROVIDED AND/OR DISCOVERED BY: 1) The vendor credits Jack C. Louis, Outpost24. 2) The vendor credits Felix Lindner, Recurity Labs.
