Microsoft TCP IP Selective Acknowledgement Denial of Service (MS10-009; CVE-2010-0242)

TCP/IP SACK is used for connections with large TCP window sizes. When SACK is enabled, if a packet or series of packets is dropped the receiver can inform the sender of exactly which data has been received and where the holes in the data are. The sender can then selectively retransmit the missing...
