TCP: C2S Ambiguity Data in SYN Packet
This protocol anomaly triggers when it detects a SYN packet that carries data. Although allowed by RFC793, because different operating systems use this data differently, these packets should be dropped.
Extended Description
The impact depends on how the implementation handles this kind of anomalous packet.
